If you're the kind of person that's constantly losing your keys or wallet, then a Bluetooth tracker may be the perfect solution. They're pocket-sized devices that are essentially designed to make your "dumb" items "smart" by adding tracking capabilities to a smartphone or tablet app.
The idea is that when it's time to head out but you can't find your things, all you need to do is bust out the app and it'll lead you right to them with the help of the tracker. Though relatively simple, there are a few technical points to consider before buying one.
Though Bluetooth trackers come in a variety of shapes and sizes, they all work the same way. You attach one to an item, sync the tracker to your smartphone or tablet via Bluetooth, and then add it to a list of devices in the app. That's it.
Once connected, you can use the app to locate the tracker by sending out an alert. The tracker can direct you to its location and will make a noise to help you find it. This, of course, requires a clear Bluetooth signal which can be affected by walls, buildings and other household/outdoor items. If the signal drops out, then some apps will also show you the tracker's last known location.
Some models, such as Apple's AirTag, also have shared or community tracking features. This turns every Apple device into a potential tracker when Bluetooth is active, even if you're outside the range of your tag.
For example, someone else's iPhone with the app enabled might detect your AirTag that is attached to an item you're looking for. The stranger's iPhone will send the location to Apple's servers, and the servers will then send that location to the Find My app, allowing it to show you where your item is.
These pocket-sized devices come in three styles:
- thin, credit-card sized ones for your wallet
- small buttons with a hole for a keyring or lanyard
- small buttons with an adhesive pad on the back.
While the first two can be swapped out across different items, adhesive models are hard to take off once attached. The pad may also lose its adhesiveness when removed, but you may be able to replace it.
Do Bluetooth trackers need batteries?
Yes, but they don't require a lot of juice so a single battery/charge will keep them going for months at a time. Some are rechargeable but have an inaccessible battery, like a phone, while others use button (aka coin) batteries that you can replace.
Then there are those with batteries that can't be recharged or replaced, the idea being that you just throw them away when the battery dies. This is very wasteful and contributes to the already significant e-waste problems in Australia.
Many Bluetooth trackers use small button batteries which can be ingested by infants and toddlers.
Bluetooth trackers that use button batteries can be dangerous to children if the case isn't secure. If the battery is easy to remove, then your child can ingest it which may result in injury or death. They're also easy to insert into orifices such as the nose or ear which can also lead to hospitalisation or lasting injury for your child.
Single use models with batteries that can't be replaced or recharged are safer as the battery can't be removed. However, these introduce their own environmental issues.

Broadly speaking, Bluetooth trackers are most useful if you're still in the area where you lost your keys, wallet or headphone case. The audio function may not be overly helpful if you're in a noisy venue like a pub or outdoors, and that's where trackers with community functions come in handy.
The main difference between Bluetooth and GPS trackers comes down to how they locate the wayward device. A Bluetooth tracker will only work if it, and the smartphone or tablet with the tracking app, are within the maximum range (usually up to 100 metres).
GPS trackers, however, receive data from a global satellite network which means you can zero in on the device from anywhere in the world provided the signal doesn't drop out. This is how features like "find my phone" work, and it's really useful if you happen to lose something outside the home. It also comes in handy if someone takes your item to lost and found or, worse, back to their place.
The catch is that GPS trackers are usually more expensive and the batteries don't last as long. While there may be a measurable difference in performance on paper, in reality there's very little difference. That said, Bluetooth does have the edge when you don't have a clear view of the sky or a mobile connection.
The associated app points you towards the Bluetooth tracker.
It's worth checking to see if the manufacturer is transparent about location data encryption and anonymity where applicable.
IP rating (water and dust resistance)
An ingress protection (aka IP) rating shows the level of water and dust resistance in the tracker. A rating of IP67 or higher will protect it from rain and if you drop it in shallow water, dirt or mud. This rating also allows it to be rinsed under tap water. Generic terms like "waterproof" or "splashproof" can be good indicators, but they're quite broad compared to a specific IP rating.
Long Bluetooth range
A long range means your phone or tablet can detect the tracker from further away. Though most trackers have a range that's big enough for your home they may not be able to find an item you've dropped outside. Bear in mind that the range will be reduced by walls and other objects. Also, claimed range rarely matches actual performance so be sure to check our Bluetooth tracker test results. Some trackers have a range of no more than 4–5 metres which may not be helpful when looking for your keys in a large home.
Audio alerts on the tracker aren't much good if they can barely muster up a whistle. A loud speaker will make the tracker easier to locate and help you hear it from other rooms or outdoors.
Low battery alert
Without battery alerts, the tracker could die and you won't be able to find your missing items.
This will ping your phone if the Bluetooth signal goes out of range, or if it detects that you've left something behind in a café, for example.
Multiple family members can use the tracker
Some manufactures let the tracker be tracked by the app on multiple devices at the same time. This can be handy if the tracker is attached to something that more than one person uses, such as car keys.
