A primary precept of the universe dictates that you’ll misplace your keys solely once you’re already late. If this occurs extra typically than you’d like, a Bluetooth tracker may also help. Connect one to your keys or stuff one in your bag (additionally they work properly with wallets and jackets) and when you may’t observe one thing down, your cellphone will make the tag ring till you discover it. These useful fobs may also ship alerts once you’re about to go away them behind and may faucet into huge networks of different smartphones to anonymously find misplaced gadgets out on the imply streets. I examined choices from all the foremost producers to seek out one of the best Bluetooth trackers for all kinds of wants.
Editor’s be aware 6/17/2024: Two of the trackers we advocate come from Tile, which was not too long ago the sufferer of a hacker who gained entry to buyer knowledge together with names, bodily addresses and cellphone numbers. We’re continually re-evaluating our high picks and can take this under consideration in subsequent story updates.
Additionally, we not too long ago obtained our arms on the Pebblebee Clip and Chipolo’s One Level trackers, each of which depend on Google’s new Discover My System community. We’re within the means of testing them and can replace this information as soon as we’ve completed.
What to search for in a Bluetooth monitoring gadget
Bluetooth trackers are small discs or playing cards that depend on short-range, low-energy wi-fi indicators to speak together with your smartphone. Connect one to your stuff and, if it’s in vary, your cellphone can “ring” the chip so you’ll find it. These monitoring units provide different options like separation alerts to inform you once you’ve left a tagged merchandise behind, or the place a misplaced merchandise was final detected. Some may even faucet into a bigger community of smartphones to trace down your gadget once you’re out of vary. Relying on what you need the tracker to do, there are just a few specs to search for when deciding which to get.
System compatibility
Like most issues from the oldsters in Cupertino, AirTags solely work with merchandise within the Apple ecosystem. The corporate has opened up entry to its Discover My community to third-party producers, together with Chipolo and Pebblebee. These finders work with Apple’s massive monitoring community, however solely pair with Apple units. Chipolo’s basic trackers will work with both Android or Apple units, as will Tile trackers. Samsung’s newest fob, the Galaxy SmartTag2, solely works with Samsung telephones, however new tags from Chipolo and Pebblebee that depend on Google’s new Discover My System community will work with any Android cellphone (working Android 9 or later).
Discovering community
Crowd-sourced discovering capabilities are what make headlines, with tales about recovering stolen gear or monitoring misplaced baggage throughout the globe. Utilizing nameless indicators that ping different individuals’s units, these Bluetooth monitoring units can probably inform you the place a tagged merchandise is, even when your smartphone is out of Bluetooth vary. Apple’s Discover My community is the biggest, with over a billion iPhones in service all working Apple’s Discover My app by default. So until an iPhone consumer opts out, their cellphone silently acts as a location detector for any close by AirTags.
Now that Google’s Discover My System community is up and working, it’s an in depth second for the biggest within the US. Like Apple, Android customers are robotically a part of the community, however can opt-out by choosing the Google providers possibility of their cellphone’s Settings app and toggling the choice within the Discover My System menu. Samsung’s SmartTag 2 and associated community additionally defaults to an opt-in standing for locating tags and different units.
Tile gives a big discovering grid, with each smartphone that runs the Tile app appearing as incognito locators. After Life360 acquired Tile, the 47 million customers of that app have been added to the 50 million present Tile customers, creating a large community.
In our exams, AirTags supplied practically real-time location knowledge and have been quickest to seek out gadgets deserted in spots round Albuquerque, together with a bar, bookstore and occasional store in Nob Hill, together with varied outside hangouts on UNM’s campus. Tile trackers and Samsung’s SmartTags have been capable of find our misplaced gadgets more often than not, although not with the identical pin-point accuracy as AirTags. Chipolo’s Spot trackers function on the identical Discover My community and carry out on par with the AirTags.
Chipolo’s basic trackers, however, don’t have a lot of a crowd-sourced community to talk of. But as we used the trackers, the dimensions of the discovering community began to really feel much less necessary within the face of typical, on a regular basis use circumstances. It was their capability to out-perform in each different approach that boosted Chipolo’s basic trackers to the highest of our record.
Separation alerts
Right here’s the place a tracker’s day-to-day utility actually shines. A separation alert lets once you’ve traveled too far out of your tagged gadgets, which is beneficial if you wish to make sure that your laptop computer bag, or jacket or umbrella all the time comes with you once you go away the home.
These notifications work once you’re out and about too. In the event you’ve obtained a Bluetooth monitoring gadget in your pockets and stroll out of a restaurant with out it, the separation alert ought to kick in, leading to fewer misplaced gadgets. This characteristic additionally tells you the place your tagged merchandise and cellphone have been final paired, permitting you to retrace your steps in the event you occur to overlook the alert.
Every tracker handles left-behind gadgets in a different way. Each AirTags and Chipolo embody the characteristic by default. Tile trackers require a yearly subscription to allow the alerts (at present $30 per 12 months). Each AirTags and Tiles can help you flip off separation alerts at sure areas, that means you may set your house as a “safe” place the place gadgets may be left behind, however alerts will nonetheless set off elsewhere. Chipolo doesn’t provide secure areas, however you may toggle out-of-range alerts on a per-item foundation.
In our exams, the Chipolo despatched an alert after we obtained between 250 and 450 ft away from our tagged merchandise. AirTags alerted us between the 600- and 1,400-foot mark. And Tiles despatched a notification after about a mean of 1,500 ft. Tile notifications weren’t constant on an iPhone, however labored properly when working with an Android cellphone.
Connectivity, quantity and design
The characteristic it’s possible you’ll use most frequently is the important thing finder operate, which makes the tracker ring once you hit a button within the app. The SmartTag2, Tile, Chipolo basic and Pebblebee trackers utilizing the Pebblebee app will even allow you to double click on the gadget itself to make your cellphone ring. AirTags and any third celebration tags working on both the Discover My (Apple) or Discover My System (Google) app don’t provide this characteristic.
The amount of the Bluetooth monitoring gadget could decide whether or not you’ll find an merchandise buried in your sofa cushions or in a loud room. AirTags have a popularity for being on the quiet facet, and that aligned with what we noticed (measuring roughly 65 decibels). Chipolo’s keychain-style tags, each the Apple-only model and the device-agnostic model, and the Tile Slim pockets tracker have been the loudest, measuring between 83 and 85 decibels.
Design will decide what you may connect the tracker to. AirTags are small, clean discs that may’t be secured to something with out equipment, that are quite a few, however that’s an extra value to think about. Each Chipolo and Tile provide trackers with holes that simply connect to your key ring, and each firms additionally provide card-shaped variations designed to slot in your pockets. Tile additionally makes Tile Stickers, that are even smaller trackers that adhere to issues like your TV’s distant.
Batteries are replaceable for AirTags, Tile Professional and Chipolo One; the primary two have a one-year battery life and the Chipolo can go as much as two years. Tile Mate and all card-shaped trackers don’t have replaceable batteries, which suggests you’ll have to exchange the complete unit each time it dies. Pebblebee trackers are rechargeable and are available in each a key fob and pockets selection.
Stalking and stealing
AirTags have gotten numerous consideration and even prompted some lawsuits for Apple because of dangerous actors planting them on individuals to be able to stalk them. Whereas this reality could not affect your shopping for determination, any dialogue of Bluetooth trackers ought to be aware what steps Apple, Google and Tile have taken to handle the difficulty. Final 12 months, all the foremost gamers within the Bluetooth tracker enterprise teamed up to fight misuse and standardize how unauthorized monitoring detection and alerts work for iOS and Android.
Lately, Tile launched a characteristic referred to as Anti-Theft Mode, which allows you to render one in every of its trackers undetectable by others. Meaning if somebody steals your tagged merchandise, they gained’t have the ability to use the anti-stalking options to seek out its exact location and disable the tracker. After all, that probably makes a Tile simpler to make use of as a stalking gadget, so to be able to allow the characteristic, you must confirm your ID and conform to a $1 million penalty for misuse.
Usually, a Bluetooth tracker could or will not be the best choice for combating theft. Anecdotal tales abound through which individuals have recovered stolen items utilizing a tracker — however different tales are extra cautionary. Neither Apple nor Google promotes its trackers or discovering networks as a strategy to take care of theft. GPS trackers, however, are sometimes marketed for simply that objective.
How we examined
Earlier than deciding on which trackers to check, we researched the sector, taking a look at consumer critiques on Amazon, Finest Purchase and different retailers, together with discussions on websites like Reddit. We additionally checked out what different publications needed to say on the matter earlier than narrowing down our picks to Apple AirTag, Tile and Chipolo trackers. When Samsung’s SmartTag 2 got here out in October of 2023, we added that to our testing, together with Pebblebee’s rechargeable Chip tracker.
Right here’s the total record of each tracker we examined:
After buying the trackers, I examined each over the course of some weeks utilizing each an iPhone 11 and a Samsung Galaxy S22 Extremely. I recreated seemingly consumer experiences, reminiscent of dropping and leaving gadgets behind at residence and out within the metropolis. I planted trackers at completely different spots close to downtown Albuquerque, principally concentrated in and across the College of New Mexico and the encircling neighborhood of Nob Hill. Every check was carried out a number of instances, each whereas strolling and driving and I used the measure distance characteristic on Google Maps to trace footage for alerts. I paid consideration to how simple the app was to make use of, how dependable the phone-to-tracker connection was and every other perks and downsides that got here up throughout common use.

Format: Disc with gap | Compatibility: Android and iPhone | Water resistance: IPX5 (splash resistant) | Battery life: 2 years | Replaceable battery: Sure | Distance for left-behind alerts: 350 ft. | Cellphone finder operate: Sure
Palms-on testing is nice at smashing assumptions, and that’s what occurred with the Chipolo One. This tracker’s crowd-sourced discovering community can not evaluate with Apple’s AirTag or Tile. In reality, once I left the Chipolo for twenty-four hours simply exterior the busy pupil union at UNM, I used to be by no means alerted {that a} member of the Chipolo neighborhood had detected my merchandise. However as I used it and pictured how most individuals would use a tracker every day, the gadget proved its value and earned its spot on my keyring.
The One is a small and colourful plastic disc with a gap. It really works with each Apple and Android units and requires an app which is straightforward to make use of and simply pairs new trackers. The app and monitoring expertise on an iPhone and a Galaxy cellphone have been practically equivalent, working equally properly on each platforms. It rang the loudest of all of the trackers, so misplaced gadgets have been shortly discovered round the home. Not like different trackers, there was by no means a delay between urgent the Ring to Discover button and listening to the trill. The ring delay for AirTag was by no means quite a lot of seconds and Tiles would usually join and ring after not more than ten seconds. Whereas that’s not a deal-breaking delay, it may add to the stress of dashing out the door.
The place the Chipolo One actually set itself aside was with its separation alerts. I might solely get a half to 2 blocks away (or a mean of 350 ft) earlier than getting an alert asking if I’d forgotten an merchandise. Neither AirTag nor Tile ever beat Chipolo to the punch. The alerts have been constant whether or not I used to be forgetting an merchandise at residence, at a espresso store, or inside my automotive.
So far as dropping stuff out within the wild, it can get you again to the spot the place your cellphone and tracker have been final paired. Meaning in the event you miss an alert or don’t have them turned on, Chipolo provides you with instructions (by way of your maps app) and take you proper to the place you left your merchandise. In a single check, I had a pal disguise the tracker close by once I wasn’t wanting. I left the realm and returned hours later, utilizing the final location data to guide me inside just a few ft of the tracker’s exact location. Ringing the tracker then made it simple to seek out. After all, if somebody walks off together with your tracked merchandise, the Chipolo might be tougher pressed that can assist you out.
In the event you’re involved about misplaced baggage once you journey or in the event you fear it’s possible you’ll lose issues on trains or buses, this isn’t the tracker for you due to its a lot smaller discovering community. However in the event you’re searching for a lifeless easy strategy to discover your keys and ensure your jacket leaves the bar once you do, the Chipolo One is tough to beat.
Chipolo will even can help you use Alexa to assist discover your keys. You will have to allow the Chipolo ability within the Alexa app and join your Chipolo account. Relying in your good residence assistant to seek out your misplaced keys may make an on-time departure even simpler.

Format: Clean disc | Compatibility: iPhone | Water resistance: IP67 (water and dust-resistant) | Battery life: 1 12 months | Replaceable battery: Sure | Distance for left-behind alerts: 1,200 ft | Cellphone finder operate: No
AirTags work with iOS’ Discover My app, so that they don’t require any extra downloads. In the event you’ve used the Discover My app earlier than, you’ll seemingly perceive how this works. These are the quietest of the trackers we examined and every time you press the Play Sound button, the tags solely ring for seven seconds. You’ll have to preserve urgent in the event you don’t discover your merchandise straight away and AirTags can’t be used to ring your cellphone.
As for separation alerts, AirTags have been constant, all the time delivering a “left behind” alert once I traveled about 1,200 ft away, or about three sq. blocks, with out an merchandise. You may flip off separation alerts for any given tracker, in addition to designate sure areas, reminiscent of your house or office, as exceptions for the notifications.
One characteristic that AirTags have that no different tag gives is the flexibility to faucet into the ultra-wideband (UWB) wi-fi protocol. This lets you play a enjoyable recreation of cold and hot with an merchandise when it’s inside about 25 ft of your iPhone. Directional arrows and a diminishing distance meter in your iPhone’s display level you to an merchandise with out having to ring it. This labored reliably about 75 % of the time in my exams; typically it was simply simpler to ring the merchandise when the directional discovering couldn’t preserve a lock on the tracker.
UWB is supported by iPhone fashions 11 and later and whereas newer Galaxy and Pixel telephones additionally help UWB, no Android-compatible tracker has but been launched. In 2021, Tile introduced one that will, however has since missed its promised launch window of “early 2022.”
AirTag’s capability to find a misplaced merchandise out within the metropolis is nearly eerie. I had somebody (who was not carrying an iPhone) take my bike with a tracker hidden below the seat to a location slightly over a half mile away. I set out a couple of minutes later and toggled on Notify When Discovered within the Discover My app. Inside three minutes, I acquired a notification that the bike had been “seen” close to an handle. Tapping on Instructions navigates to Apple Maps, which took me to a spot about 30 ft from the bike. Had it been obscured from view, I may have then used the Discover Close by button to activate the UWB finding options. Ringing the tag was too quiet to listen to on the sidewalk.
If you need the identical scary-precise neighborhood discovering options, however with a louder ring and a gap within the tracker, the Chipolo One Spot is a strong possibility. It doesn’t provide UWB capabilities, nonetheless, and the separation alerts are the identical as with AirTags (letting you get 1,200 ft away earlier than a ping, versus a mean of 350 ft with our high rec, Chipolo One basic).
Or, for a chargeable possibility, the Pebblebee Clip is an effective AirTag different. True, you may swap out the battery in Apple’s discs, however charging your tracker by way of USB-C each few months is likely to be simpler. The Pebblebee works with Apple’s Discover My community and has the identical setup as an AirTag. In my exams, it was noticed simply as shortly as Apple’s tracker, and the left-behind alerts went off about the identical distance away.
However the Pebblebee has just a few benefits over AirTags: The black disk has a built-in metallic attachment level and features a small carabiner clip, so for many conditions, you gained’t want an extra accent. The Pebblebee is much louder than Apple’s tracker, too. I additionally like that once you ping it from the app, it continues ringing till you hit cease as an alternative of going silent after seven seconds. Pebblebee makes a chargeable pockets tracker as properly, which can be simpler to slip in a billfold than the rounded AirTag. One phrase of warning, nonetheless: In the event you’re going to make use of it with Discover My, don’t set it up with Pebblebee’s personal app beforehand. In the event you do, you’ll must do a manufacturing facility reset earlier than it’ll work with Apple’s app.
- Huge discovering community
- Correct UWB for close by finding
- iPhone solely
- Solely rings for 7 seconds at a time
- No attachment level

Format: Rectangular fob with gap | Compatibility: Android and iPhone | Water resistance: As much as 3 ft | Battery life: 1 12 months | Replaceable battery: Sure | Distance for left-behind alerts: 1,500 (requires subscription) | Cellphone finder operate: Sure
Tile will work with both Android or Apple units, however the expertise is a lot better on Android. Sure connectivity points and an absence of alerts that plagued the iPhone expertise didn’t present up in exams with the Galaxy cellphone. One caveat to notice is that Tile requires a subscription to allow separation alerts. Tile Premium goes for $3 monthly or $30 per 12 months and consists of location historical past and merchandise reimbursement of as much as $100 on gadgets that you just register with the corporate, they’ll additionally ship out a recent battery every year. Tile stands out as the one tracker firm providing reimbursement — even with no subscription, they’ll pay out as much as $25 for gadgets that you just register with them.
The Tile Professional is a key-fob formed gadget with a metallic keychain gap that feels sturdy. The Professional’s ring was only a few decibels quieter than the Tile Mate (78 versus 82 decibels), however the connectivity vary was higher with the Professional, and it was extra correct in finder community exams. On high of that, that is the one present Tile gadget with a replaceable battery, which lasts about one 12 months.
For the lost-item exams, I had a pal take the Professional to random areas. After turning on the Notify When Discovered characteristic, an alert would arrive between 5 and ten minutes later saying my misplaced merchandise was “found by the community.” The map particulars have been sometimes correct inside about 100 ft or so, although it often thought the Tile was at a enterprise subsequent door to the place it really was. With out the UWB characteristic, precision discovering of an merchandise was trickier. In a single check, the tracker ended up in a loud pub. Whereas the instructions pointed me to the best location, it will have been troublesome to seek out the merchandise if I hadn’t noticed my pal, because the ring operate was ineffective among the many din.

- Louder than AirTag
- Discovering community is first rate
- Requires a subscription for left behind alerts

Nothing can beat the vastness of Apple’s Discover My community, because it depends on each close by iPhone to assist find AirTags. The variety of Samsung telephones within the US could also be smaller than the variety of Apple handsets on the market, but it surely’s nonetheless important. The brand new SmartTag 2 depends on these telephones to supply a discovering community that will not greatest Apple’s, however is bigger than anything on the market for Android in the intervening time. After all, as soon as Google unleashes its expanded Discover My System community, every part will change.
The SmartTag 2 solely works with Samsung units and after testing one out with a Galaxy S23, I used to be impressed how shortly it was capable of finding tagged gadgets out within the wild, although the precision didn’t fairly match that of Apple. Of all of the trackers I’ve tried, I just like the design of the SmartTag one of the best. It’s an rectangular fob with an enormous gap for attaching on to your keys, or you should purchase the non-compulsory silicone case and ring Samsung gives. Its quantity is louder than the AirTag and the Tile Professional, however not as loud as both the Chipolo One or the Pebblebee Clip. You can too change the tag’s ringtone or double squeeze it to ring your handset, each issues that you would be able to’t do with AirTags.
Setup is straightforward as properly: when you take away the plastic pull tab, your cellphone senses the tracker and walks you thru the usual permissions (location providers, notifications) and warnings (don’t use the tracker on individuals). The companion app, SmartThings Discover, tracks your Samsung units and the SmartTag with an intuitive and clear Google Maps-based interface.
As for the way the tag works in observe, I discovered the left behind alerts triggered reliably once I obtained about three blocks (1,200 ft or so) away when strolling and about eight blocks away when driving. That’s far longer than Chipolo’s alerts, slightly longer than Apple’s notifications and about on par with Tile’s left-behind characteristic.
When the tag is out of vary and also you allow Misplaced Mode, you’ll get an alert when it’s noticed by one other Samsung cellphone. The tag additionally makes use of NFC to show your contact data and a customized be aware to anybody who finds the tracker, whatever the model of smartphone they carry. After all, whoever finds it will have to know to carry it to the again of their cellphone to get the message, and it was tougher to set off with my iPhone when the tag was within the silicone holder.
To check the discovering community, I requested a pal (with no cellphone of their pocket) to wander a half mile away with the tag. About 12 minutes after turning on Misplaced Mode, I obtained a message that the SmartTag was “spotted by a nearby device” with a dropped pin. I tapped Navigate within the app, which opened Google Maps and led me to a degree instantly throughout a reasonably busy road from the place my pal was standing. If I’d left the tag behind someplace I’d not too long ago been, simply seeing the situation on the map would have been sufficient to jog my reminiscence as to the place I may need dropped my stuff. But when somebody had stolen the tagged merchandise and I used to be wandering the streets attempting to get it again, vigilante fashion, it might not have been exact sufficient to assist. It will not be as correct because the iPhone-and-AirTag combo, however the SmartTag 2 is a strong entry within the Bluetooth tracker market and a very good possibility you probably have a Samsung cellphone.
- Discovering community is massive
- Engaging and helpful design
- Solely works with Samsung telephones

Format: Thick bank card | Compatibility: Android and iPhone | Water resistance: As much as 20 ft | Battery life: 3 years | Replaceable battery: No | Distance for left behind alerts: 1,400 ft. | Cellphone finder operate: No
The Tile Slim is louder than each the Professional and the Mate, and practically equals the loudest tracker we examined, the Chipolo One. It really works with each Android and Apple units and its thick bank card form matches within the slots of a typical pockets (although it typically gained’t join when inside an RFID-blocking pockets). The separation alerts you’ll get in the event you pay for a Tile subscription activate at about the identical distance because the Tile Professional, letting you get round 1,500 ft away earlier than pinging you a couple of left-behind merchandise. When utilizing an iPhone with Tile trackers, separation alerts not often got here and connectivity between the cellphone and tracker was spotty at greatest, even in shut proximity. In the event you use an iPhone, the Chipolo Card Spot is equally loud, runs on Apple’s huge Discover My community and persistently provides you a left-behind alert at round 1,200 ft.

Bluetooth tracker FAQs
Which Bluetooth tracker has the longest vary?
Each the Tile Professional and the Samsung Galaxy SmartTag2 declare a most vary of round 400 ft, which is longer than the 200-foot declare for many of Chipolo’s tags. Apple doesn’t make comparable claims for AirTags. Any Bluetooth sign, nonetheless, depends on just a few components. Obstacles like partitions and other people can block the sign, so a transparent line of sight is the one strategy to obtain the utmost vary. Different indicators, like Wi-Fi, may also intrude with Bluetooth connections. Even excessive humidity can have an impact and reduce the gap at which your cellphone will hook up with your tracker.
Bear in mind, when contemplating the vary of Bluetooth trackers, the dimensions of the “finding network” additionally comes into play.

Bluetooth trackers are designed to trace small, private gadgets like keys, jackets, backpacks and the like. All trackers have safeguards to ban the tag from getting used to stalk individuals, so most will alert somebody if a tracker that doesn’t belong to them is detected following them. Meaning a automotive thief could get tipped off that there’s a tracker within the automotive they’re attempting to steal. That mentioned, you’ll see loads of tales about individuals discovering their automotive because of a Bluetooth tracker. Some police departments have even handed out trackers to fight excessive charges of carjacking.
