Our quick picks

The reasoning, the specifications that actually matter and every drawback are below.

The thing to understand about Bluetooth trackers is that you are not buying a device, you are buying a network. The tracker itself is a coin-cell battery, a Bluetooth radio and a small speaker, and its own range is about the width of a house. What actually finds a bag you left in a taxi across town is other people’s phones quietly noticing your tracker and reporting where they saw it.

That single fact decides your purchase, and it makes the decision much simpler than the product pages suggest. The right tracker is the one whose network is largest where you live, and that network is determined by the phones around you, not by the tracker.

Which leads to the shortest version of this guide:

• You use an iPhone: buy AirTags. Apple’s Find My network is made of every iPhone in the world and no other network comes close.
• You use a Samsung Galaxy phone: buy SmartTag2. It taps Samsung’s network and integrates with the phone you already carry.
• You use another Android phone: look at a tracker that works with Google’s network, or use Tile, which works on both platforms with its own smaller network.
• The item needs to be findable by whoever finds it, on either platform: Tile, because it is cross-platform.
• You want to track a dog that roams, a car, or a person who has consented: none of these. You want a GPS tracker, and we explain why below.

Two things these are not

They are not GPS trackers

None of these products contains GPS. They have no idea where they are. They broadcast a Bluetooth signal and wait for a passing phone to report the sighting, which means a tracker in a place with no phones is invisible — a field, a forest, a remote road, the middle of a large parking lot at three in the morning.

That is why a Bluetooth tag is the wrong tool for a dog that gets out, a cat that roams, a bike left in a rural area or a vehicle. For those you want a device with its own GPS and its own cellular connection, which costs more and needs a subscription, and which is a different product category. Apple says plainly that AirTags are for items, not for tracking people or pets, and that is the correct framing for all of these.

They are not recovery devices

A tracker tells you where your thing is. It does not get it back. If the answer turns out to be a stranger’s house, the right move is to give the information to the police and let them handle it — not to go there. Every year people are hurt confronting someone over a stolen phone or bike, and police may or may not act on tracker data. Buy one to find the keys down the side of the sofa and the bag left at the airport, which is what they are excellent at, rather than as a plan for theft.

Unwanted tracking: the part that deserves a section

These devices are small, cheap and silent, and they can be used to follow a person. That is stalking, it is illegal in many jurisdictions, and it is not a use anyone should be experimenting with. We are saying that plainly because it is the one genuine harm in this category.

What has changed for the better: both major phone platforms now detect unknown trackers. An iPhone will alert you if an AirTag or a Find My tracker that is not yours has been traveling with you, and Android does the same for the trackers on its network. Both can make the tag play a sound, and both can show you its identifier.

If your phone tells you an unknown tracker is moving with you, do not dismiss it. Follow the phone’s prompt to make it beep, and search your bag, coat, stroller and car — wheel arches, under seats, in seat pockets, inside luggage linings. Your phone can also show a serial number, which is useful to record. If you find one you cannot explain, or you have any reason to think someone has placed it deliberately, contact your local police rather than handling it alone; in the United States, the National Domestic Violence Hotline can also advise on what to do next, and support services in other countries do the same.

One practical detail worth knowing: removing the battery stops the tracking, but it also removes evidence. If the situation is one you may want to report, photograph where you found it first.

What actually matters when you are comparing them

• Which network it uses. The most important specification, and the one least often stated plainly. Apple Find My, Google’s network, Samsung’s network, or Tile’s own. Match it to the phones around you.
• Precision finding, and whether your phone supports it. Some tags include an ultra-wideband radio, which lets a recent phone point you the last few feet with an arrow and a distance. This is what turns “it is somewhere in this room” into “it is under that cushion.” It needs both a UWB tag and a UWB phone.
• Replaceable battery or sealed unit. A tag that takes a standard CR2032 coin cell runs for about a year and then costs almost nothing to keep going. A sealed tag lasts around three years and is then rubbish. This distinction is rarely on the front of the box and matters a great deal over five years.
• How loud it is. The speaker is what you actually use for keys down the back of the sofa, and the difference between tags is substantial. If the main use is finding things inside your own home, loudness beats every other feature.
• Shape. A disc goes on a keyring; a card goes in a wallet or a passport holder. A disc in a wallet is uncomfortable and a card on a keyring is not a thing. Buy the shape for the object.
• Whether it has a hole in it. Some of the most popular tags do not, so you also need a case or holder to attach them to anything. Factor that in.
• Water resistance. Keys and bags get rained on. An IP rating is worth having.
• Subscription features. The basic finding never needs a subscription on any of these. Some brands put extras behind one. Check which side of that line the feature you want falls on.
• Multi-packs. Almost always the sensible buy, because the second and third useful place to put one occurs to you about a week after the first.

The Bluetooth trackers we would actually buy

Ratings and review counts were checked as we wrote this. A warning about searching in this category: the first page of results for almost every tracker is dominated by cases, holders, keyring adapters and battery replacements rather than trackers. Read the title before you order, or you will receive a silicone sleeve.

1. Apple AirTag 4-Pack — best overall if your household uses iPhones

Rated 4.8 stars across more than 144,000 ratings. That is the highest rating and one of the deepest review bases of any product we have covered anywhere on this site, and in a category where the product is the network, it is the clearest signal available.

The reason AirTags win for iPhone users is not the hardware, which is a coin cell and a speaker like everything else. It is that every iPhone in the world is a node on the network, anonymously and by default. In a city, an AirTag left in a taxi updates its position within minutes. No other network has that density, and none is likely to.

It also has precision finding via ultra-wideband, which on a recent iPhone gives you an arrow and a distance for the final few feet — the feature that makes the difference between knowing the keys are in the house and actually finding them. The battery is a standard CR2032 you replace yourself in about ten seconds, once a year.

Buy the four-pack rather than one. The second, third and fourth useful place to put a tracker occurs to everyone within a two weeks: keys, wallet or bag, suitcase, and one spare for whatever keeps going missing.

• Highest rating and deepest review base in the category by a wide margin
• The densest finding network in existence, by a very long way
• Ultra-wideband precision finding on recent iPhones
• User-replaceable CR2032 battery, about a year per cell
• Waterproof rated and robust
• Four-pack is the right quantity for a household

The catch: it is useless as a tracker if your household is on Android — an Android phone can warn you that an unknown AirTag is following you, but cannot set one up or use it to find your own things. It has no hole to attach it to anything, so you need a keyring holder or a case, which is an extra purchase everyone discovers at unboxing. The speaker is quieter than Tile’s, so for finding things inside the house by sound alone it is not the best. And engraving makes it non-returnable, which catches people out.

2. Apple AirTag, single — best way to try one, and the one with the most ratings anywhere

Rated 4.7 stars across more than 204,000 ratings, which is the largest number of ratings on any product in this guide. Identical hardware to the four-pack; the only difference is quantity.

Buy the single if you have exactly one thing you keep losing — almost always keys — or if you want to find out whether you will actually use one before committing. It is also the right purchase as a small gift, or to put in a suitcase before a trip and then leave there permanently, which is one of the really best uses of the whole category.

On checked luggage specifically: a coin-cell tracker in a suitcase is allowed and has become common enough that airline staff are used to being shown a location. It will not make a lost bag come back faster on its own, and being able to say “it is still at the airport you flew me out of” changes the conversation considerably.

• The most-rated product in this guide
• Same hardware, network and precision finding as the four-pack
• Right size purchase for one specific problem
• Excellent permanent resident of a suitcase
• Small, easy gift that does not need to fit anything
• Replaceable coin cell

Where it falls short: per tracker it is worse value than the four-pack, and most people end up wanting more. Everything else we said above applies: iPhone-only for actual use, no attachment hole, and a modest speaker. If you already know you want two or more, the four-pack is the purchase.

3. Samsung SmartTag2 — best for a Samsung Galaxy household

Rated 4.6 stars across roughly 6,100 ratings. Bluetooth plus ultra-wideband, IP67 water and dust resistance, and a keyring hole, which after the AirTag is a welcome thing to be able to write.

If your phone is a Galaxy, this is the equivalent of an AirTag for you: it uses Samsung’s own finding network, it integrates into the phone software you already use rather than a separate app you forget about, and it does precision finding with a compatible Galaxy phone.

The network is smaller than Apple’s in absolute terms, but network density is regional and Galaxy phones are extremely common in many markets. In a place with a lot of Samsung phones around you, this performs very well; in a place where almost everyone has an iPhone, it will be slower to report.

• Tight integration with Galaxy phones and Samsung’s finding network
• Ultra-wideband precision finding with a compatible Galaxy phone
• IP67 rated, and it has a keyring hole built in
• Replaceable coin cell with a long stated life
• Solid rating on a reasonable review base
• Can also trigger smart-home routines, which is a useful extra

What owners complain about: it is a Samsung-ecosystem product — full functionality expects a Galaxy phone and a Samsung account, so it is a poor choice on a Pixel or another Android brand and useless on an iPhone. The network depends entirely on how many Samsung phones are near your lost item, which varies a lot by country. And reviewers note the app pathway is buried in Samsung’s software rather than being an obvious standalone app.

4. Tile Slim — best for a wallet, and best if the household is mixed

Rated 4.5 stars across more than 13,700 ratings. A card-shaped tracker about the thickness of a few credit cards, made to live in a wallet, a passport holder or a laptop sleeve.

Two reasons to choose it. First, the shape: a disc-shaped tracker in a wallet is a lump you notice every time you sit down, and a card is not. If the thing you lose is your wallet, this is the correct product and the platform question is secondary.

Second, Tile works properly on both iOS and Android. If your household has an iPhone and an Android phone, or you want your partner to be able to ring your keys, Tile is the only actually cross-platform option among the major brands. Its own finding network is much smaller than Apple’s or Samsung’s, and it covers both platforms rather than one.

• Card shape that actually fits a wallet comfortably
• Works fully on both iOS and Android
• Deep review base at a good rating
• Loud enough to find by ear, which is the main in-house use
• Shareable with family members across platforms
• No subscription needed for basic finding

The downside: the battery is sealed — around three years and then the whole thing is waste, which is both worse value and worse for the environment than a coin cell you swap. Tile’s network is far smaller than Apple’s, so out in the world it reports less often and less quickly. There is no ultra-wideband precision finding. And some of the more useful extras sit behind a subscription, so check which features you are counting on.

5. Tile Pro — loudest, longest Bluetooth range, replaceable battery

Rated 4.4 stars across roughly 4,000 ratings. The biggest tracker here, and that size buys three specific things: a noticeably louder speaker, a longer Bluetooth range, and a battery you can replace.

If most of your losing happens inside your own home — keys, a remote, a bag, a set of headphones — then loudness is the feature that matters and the network is almost irrelevant, because your own phone will find it directly. On that basis the Tile Pro is arguably the most practically useful tracker in this guide, and it is the one we would pick for someone who mostly misplaces things rather than loses them.

It also has a keyring hole, works on both platforms, and takes a replaceable coin cell, which puts it ahead of the Tile Slim on longevity.

• The loudest tracker here, which is what you actually use at home
• Longer Bluetooth range than the smaller tags
• Replaceable battery, unlike the Slim and the Mate
• Works on both iOS and Android
• Keyring hole built in
• Good choice for anyone who misplaces rather than loses things

What you give up: at 4.4 stars the complaints are real — some reviewers report the app being slower or less reliable than the platform-native options, which is the recurring theme for third-party trackers. It is physically larger and thicker, so it is obvious on a keyring and wrong for a wallet. No ultra-wideband. Tile’s network remains the smallest of the majors, so for something lost out in the world an AirTag on an iPhone will do better. And check the subscription boundaries before relying on a particular feature.

6. Tile Starter Pack — best bundle if you want two shapes

Rated 4.4 stars across roughly 1,700 ratings. A Tile Mate and a Tile Slim together — a keyring disc and a wallet card — which is the pairing most people actually need.

This is the sensible purchase for a cross-platform household starting from nothing, because the two things almost everyone loses are keys and a wallet, and they need different shapes. Buying both separately costs more and buying two of the same shape means one of them lives somewhere it does not fit.

It is also a good gift for a household where you do not know what phones everyone has, since Tile does not care.

• Covers the two things people actually lose, in the right shapes
• Cross-platform, so it works for anyone
• One purchase rather than two
• Sensible gift when you do not know the recipient’s phone
• No subscription for basic finding
• Shareable within a household

The part that annoys people: both tags in this pack have sealed batteries, so in roughly three years you replace both rather than swapping two coin cells. The shallowest review base of our picks. Tile’s network is the smallest of the majors. And neither has ultra-wideband, so the last-few-feet search is by ear rather than by arrow — which is fine, because Tile is loud.

The ones that did not make it

• Chipolo POP. Truly interesting — a single tag designed to work with either Apple’s or Google’s network, which on paper is the best of both. The rating does not support it: about 3.9 stars on more than 1,300 ratings, with complaints centered on setup and reliability. We would very much like a well-executed version of this idea; we cannot recommend this one. Chipolo’s other models are worth watching.
• Cases, holders, keyring adapters and battery-replacement kits. These dominate the first page of results for almost every tracker search, above the trackers. You will need a holder for an AirTag, but buy it knowingly rather than instead of the tracker.
• Unbranded trackers on no major network. A tracker with its own tiny proprietary network is a Bluetooth beacon with an app. It will find things within Bluetooth range of your own phone and nothing else, which is a fraction of what you are buying one for.
• Trackers marketed for pets, children or vehicles. Bluetooth tags have no GPS. For an animal that roams or a vehicle you want a cellular GPS tracker with a subscription, which is a different product with different costs. Buying a Bluetooth tag for this is the most common mistaken purchase in the category.
• Anything sold on the promise of recovering stolen property. It will tell you where the item is. Retrieving it is a matter for the police, and the honest expectation is information rather than recovery.
• Sealed-battery tags, where a replaceable-battery equivalent exists. Three years and into the bin is worse on cost and on waste. Prefer the coin cell where the shape allows it.

Choosing without overthinking it

• iPhone household? AirTags, four-pack. Nothing else is close on network density.
• Galaxy household? SmartTag2.
• Mixed household, or you want anyone to be able to ring it? Tile.
• Is it going in a wallet? A card shape, so Tile Slim.
• Do you mostly lose things inside your own house? Buy the loudest one, which is Tile Pro. The network barely matters for that.
• Do you want the last-few-feet arrow? You need ultra-wideband on both the tag and your phone — AirTag with a recent iPhone, or SmartTag2 with a recent Galaxy.
• Do you care about five-year cost and waste? Choose replaceable coin cells: AirTag, SmartTag2, Tile Pro.
• Is it for a pet, a child or a car? None of these. A cellular GPS tracker, with a subscription.
• Buying it as a gift and unsure of their phone? Tile, because it does not care.
• Going on a trip? Put one in the suitcase now and leave it there permanently. It is the single best use of one of these.

Getting the most out of them

• Put one in your suitcase and forget about it. Not in the outside pocket — deep inside, in a pocket of the lining, where it cannot fall out or be removed casually.
• Name them properly in the app, and set the item type if the app offers it. “Tag 1” is useless six months later.
• Turn on separation alerts if the platform offers them. Being told you have walked away from your keys is worth more than being able to find them afterwards.
• Use the sound first, not the map. For anything inside your own home the speaker finds it in seconds and the map will only tell you it is in your house, which you knew.
• Replace the battery on a schedule, once a year for a coin-cell tag, rather than waiting for a low-battery warning you will ignore. Use a plain lithium CR2032 — some are coated with a bitter anti-swallow agent that prevents contact, and the tag then will not work.
• Keep coin cells away from small children, before and after fitting. A swallowed button cell is a medical emergency, and the loose spare is the real risk rather than the one inside the tag. Store them out of reach and dispose of used ones somewhere a child cannot reach.
• Register and keep the serial numbers, in case you need to report or identify a tag later.
• Do not hide one in something you do not own, and do not put one in a gift without telling the person. That is the line between an item tracker and surveillance.
• Share them with the household where the platform allows it, so whoever is looking can look.
• Do not put one on a bike as your only security. It tells you where the bike went; a good lock stops it going.

Frequently asked questions

Do AirTags work with Android?

Not for your own use. You cannot set up or track an AirTag from an Android phone. Android can detect an unknown AirTag traveling with you and alert you to it, which is a safety feature rather than a tracking feature. If your household is on Android, buy a tracker on a network your phones belong to.

How far do Bluetooth trackers work?

Directly from your own phone, roughly the range of Bluetooth — tens of feet, less through walls. Beyond that, range is not the right concept: the tracker is found by other people’s phones reporting sightings, so what matters is how many compatible phones pass near it. A tracker somewhere with no phones cannot be located at all.

Do they need a subscription?

Basic finding does not, on any of the trackers here. Some brands put extra features behind a subscription, so check whether the specific feature you want is included before you rely on it.

How long does the battery last?

About a year for tags with a replaceable CR2032 coin cell, and roughly three years for the sealed ones, after which the sealed tag is finished. Over five years the replaceable-battery tags work out considerably better on both cost and waste.

Can I use one to track my dog or my child?

These are not the right tool. They contain no GPS and rely on nearby phones, so an animal that gets into a field or a wood is simply invisible. For a pet that roams, or anything where you truly need to know a location on demand, you need a cellular GPS tracker with a subscription. Apple states directly that AirTags are for items, not for people or pets.

Can someone use one of these to track me?

It is possible, which is why both iPhone and Android now alert you when an unknown tracker has been traveling with you. If you get that alert, do not dismiss it: follow the prompt to make the tag play a sound, search your bag, coat and car thoroughly, and note the serial number the phone shows you. If you find something you cannot explain, contact your local police rather than dealing with it alone. Using a tracker to follow someone without their knowledge is stalking and is illegal in many places.

Are Bluetooth trackers allowed in checked luggage?

Yes — coin-cell trackers in checked bags are widely accepted and have become common. Put it deep inside the case rather than in an outer pocket, and treat the location as information to give airline staff rather than as a way of retrieving the bag yourself.

Which tracker is loudest?

Among our picks, the Tile Pro. If most of your searching happens inside your own house, loudness is the feature that matters most and the finding network barely matters at all, because your own phone is in range.

Will a tracker get my stolen property back?

It will tell you where it is. Recovery is a matter for the police, and their response varies. Never go to an address yourself. Buy one for the bag left in a taxi and the keys behind the sofa cushion, which is what they do brilliantly.

If you only read one section

If your household uses iPhones, buy the AirTag four-pack and a keyring holder to go with it — the network is the product, and Apple’s is in a different league. On a Galaxy phone, the SmartTag2 is the equivalent. In a mixed household, or for a wallet, Tile Slim is the one that works for everyone, and the Tile Pro is the loudest and the best at the job most of us actually need: finding something that is definitely in this house.

And keep the expectations right. These find lost things, they do not recover stolen ones, and they are not GPS. Put one in your suitcase, put one on your keys, turn on separation alerts, and you will get almost everything this category has to offer.
