Bluetooth tracker detector for Android
Know when a hidden tracker moves with you.
TrackerScan listens for AirTags, SmartTags, Tile and other Bluetooth trackers in the background, warns you when the same one keeps turning up where you go, and helps you find it. Free for 7 days, no payment details.
The problem
Made to find keys. Small enough to hide.
An item tracker is good at finding a lost bag. The same things make it work when someone hides it on you.
It is the size of a coin
It fits under a car seat, in a wheel arch, in the lining of a bag, in a coat pocket or inside a gift.
It runs for months
One battery lasts that long. Nobody has to come back to charge it.
It needs no SIM card and no GPS
Other people's phones that pass a tracker relay where it is to its owner, usually with some delay. So it works wherever people are.
Your phone warns about some, not all
Android's own alerts work with AirTags and with tags in Google's Find Hub network, says Google's help page (November 2026). A Samsung SmartTag or a Tile is not on that list.
How it knows
One place is a coincidence. Three is a pattern.
A tracker in the seat next to you on the train is gone at the next stop. One that is still with you at the third place you go to is travelling with you. At the recommended setting TrackerScan warns when it heard the same tracker at three places, over at least an hour.
17:25, leaving work
It hears an AirTag
TrackerScan checks every 15 minutes and notes the place, on your phone. Nothing to say yet. It could be a colleague's keys.
18:10, the supermarket
The same AirTag again
A second place. Still no alert.
19:05, home
A third place
The same tracker at three places you went to, 1 h 40 min after the first.
A moment later
Your phone tells you
“Unknown tracker moving with you. AirTag seen at 3 places over 1 h 40 min. Tap to see where and what to do.”
A warning that shows its reasons.
A warning without reasons only scares you. TrackerScan gives every tracker a risk level and shows what it is based on.
- Where and how long The number of places, the first and the last time it was heard, and every sighting.
- Its owner Whether the tracker is near its owner or away from them.
- Warning signs A tracker that kept its identifier for over a day, for one. Genuine Find My trackers change it at least once a day; clones do not.
- Your own tags stay quiet Mark a tracker as ignored and it does not alert again.
The screens on this page show example data.
Then find where it is.
Knowing that a tracker is near is half of it. TrackerScan helps you narrow down where.
- Scan nearby Every tracker in range right now, strongest signal first. A scan runs for up to two minutes.
- Warmer, colder A ring that fills as you get closer. It is approximate, from far or blocked to very close.
- Play a sound On the trackers that can ring, such as AirTags and Find Hub tags.
- No sound A speaker can be removed. The app lists where to look.
What to do when you have found it
-
Leave it on
If you think someone is tracking you, contact the police or a support service before you remove or disable the tracker.
-
Identify it
Ask the tracker for its maker and model, or hold it against your phone and read its NFC tag for the maker's page with the serial number.
-
Export its history
Every sighting of the tracker as a file, for your own records or a police report.
-
Keep the tracker
It may be evidence. The file and the serial number say which one it was.
Which trackers it hears
| Tracker | Can play its sound |
|---|---|
| Apple AirTag and other Find My trackers | Yes |
| Google Find Hub tags | Yes |
| Pebblebee | Yes |
| Other tags built to the industry's unwanted-tracking standard | Yes |
| Samsung Galaxy SmartTag | No |
| Tile | No |
| Chipolo | No |
A warning is a reason to look, not proof.
And no warning does not mean there is no tracker. TrackerScan finds Bluetooth tags. It cannot hear:
- GPS trackers with a SIM card They report over the mobile network and are usually invisible to Bluetooth.
- Trackers that are off or out of range A tracker that sends nothing cannot be heard.
- Every model and firmware New models and updates can change what a tracker sends.
If you still suspect tracking, check your car and bags, or contact a domestic-violence service or the police.
An app against tracking should not track you.
TrackerScan needs your location to tell whether a tracker moves with you, even while the app is closed. So it keeps that on your phone.

Questions
My phone already warns about unknown trackers. Why TrackerScan?
Android's own alerts work with AirTags and with tags in Google's Find Hub network, according to Google's help page (November 2026). TrackerScan also listens for Samsung SmartTags, Tile and Chipolo. It shows why it warned, keeps 30 days of history on your phone, and lets you choose how soon it warns.
How does TrackerScan know a tracker is following me?
It notes each tracker it hears, and where your phone was at that moment. When the same tracker shows up in several places you go, over a stretch of time, it warns you, with a risk level and the reasons.
How soon does it warn?
At the recommended setting: when the same tracker was heard at three places you went to, over at least an hour (four places for a Tile). You can make it warn sooner, with more false alarms, or only after more places.
Will it warn about my own trackers?
It can at first: it does not know which tags are yours. Mark a tracker as ignored and TrackerScan does not alert about it again. Trackers that pass by once, on a train or in a shop, do not cause an alert.
What it hears and what it keeps
Can it find an AirTag on Android?
Yes. TrackerScan hears Apple AirTags and other Find My trackers, Samsung Galaxy SmartTags, Tile and Google Find Hub tags. It can play an AirTag's sound and help you find it with a warmer and colder signal meter.
Can someone who picks up my phone see the alert?
The alert is marked private. If your phone hides sensitive notifications on the lock screen, it reads only: TrackerScan, tap to open. What was found shows after you unlock.
Why does it ask for location, also in the background?
To tell whether a tracker moves with you from place to place, even when the app is closed. Those places stay on your phone and are deleted after 30 days; they are never sent to us.
Does it find every tracker?
No app does. TrackerScan cannot hear trackers that use the mobile network or GPS without Bluetooth, trackers that are switched off, or every model and firmware version. A warning is a reason to look, not proof.
Price and help
What does it cost, and what happens after the trial?
Each Google account gets one free trial of 7 days, with no payment details, so nothing is charged when it ends. After it, protection pauses until you subscribe: €9.99 a month in the euro countries, through Google Play, which shows the price for your country before you buy. Cancel any time in Google Play. Your tracker history stays on your phone either way.
Which phones can run it?
Android phones with Bluetooth, from Google Play. There is no iPhone app; iPhones already warn about AirTags and some other trackers themselves.
Who makes TrackerScan?
OID4Pay B.V. in Amsterdam, the Netherlands (KvK 42074824). Write to hello@trackerscan.app. The privacy policy says what is stored, where, and for how long.
I found a tracker. What now?
If you feel unsafe, contact the police or emergency services first, before you remove or disable the tracker. TrackerScan can read the tracker's NFC tag for the maker's page with its serial number, and export its history as a file. Keep the tracker; it may be evidence.
