Everything you need to track down a lost device
BlueKit turns your iPhone into a Bluetooth detector. It listens for the signal your devices broadcast and shows you whether you're getting closer.
Live signal strength
A five-level signal meter updates as you move. Stronger means closer, so you can play hot-and-cold around the room until you find it.
Distance estimate
See roughly how far away each device is, in meters, calculated from its Bluetooth signal and refreshed every couple of seconds.
Sound and vibration alerts
Turn on alerts and your iPhone beeps or vibrates when you're within a few meters, so you can keep your eyes on the floor instead of the screen.
Favorites
Mark the devices you care about, like your AirPods or your watch, so they stand out every time you scan.
Map view
Open a map of where you're searching to keep your bearings while you retrace your steps.
Works with the Bluetooth devices you carry
If it's powered on and broadcasting Bluetooth nearby, BlueKit can pick it up. Apple devices are recognized by name and get their own icon.

Can't find it yet? Try this
BlueKit can only detect a device while it's sending a Bluetooth signal. These checks solve most searches.
Turn Bluetooth on
Bluetooth must be on in Control Center or Settings, and BlueKit needs Bluetooth permission.
Take it out of the case
Earbuds inside a closed charging case often stop broadcasting. Single earbuds out in the open are easier to detect.
Check the battery
A device with an empty battery can't send a signal, so it won't show up in any Bluetooth scan.
Stay in range
Bluetooth usually reaches around 10 meters (33 feet), less through walls. Search room by room where you last used it.
Move slowly
Signal readings bounce around. Pause for a few seconds in each spot and watch the trend, not a single number.
Unpair it from other devices
Headphones connected to another phone or laptop may stop advertising. Turn Bluetooth off on your other devices while you search.
Your search stays on your iPhone
BlueKit reads Bluetooth signals directly on your device. You don't need an account, and your scan results and favorites are never uploaded.
- No account or sign-up
- Scan results and favorites stay on your iPhone
- Location is used only to show the map
- No tracking permission requested

How does BlueKit find a lost Bluetooth device?
Most Bluetooth devices constantly broadcast a small radio signal. BlueKit measures how strong that signal is on your iPhone and turns it into a signal meter and a distance estimate. As you walk toward the device the signal gets stronger, which tells you you're getting closer.
Can BlueKit find my AirPods?
Yes, as long as they're powered on and within Bluetooth range. AirPods broadcast most reliably when they're out of the charging case or the lid is open. If they're in a closed case or the battery is empty, they may not show up.
Is BlueKit different from Apple's Find My?
Find My shows where your Apple devices were last seen on a map and can play a sound on them. BlueKit works up close: it shows the live Bluetooth signal of any nearby device, including headphones, trackers and watches from other brands that aren't in Find My. Many people use both.
How far away can BlueKit detect a device?
Bluetooth typically reaches about 10 meters (33 feet) indoors, sometimes more in open spaces and less through walls. Start searching where you last used the device.
How accurate is the distance?
It's an estimate. BlueKit calculates distance from signal strength, and walls, furniture, bodies and even the device's orientation change that signal. Treat it as a guide to whether you're getting warmer or colder, not as a precise measurement.
Can it find a device that's turned off or has a dead battery?
No. A device that's off or out of battery doesn't send a Bluetooth signal, so no Bluetooth scanner can detect it. In that case, check Find My or the device maker's app for its last known location.
Why doesn't my device appear in the list?
Make sure Bluetooth is on and BlueKit has Bluetooth permission, take earbuds out of their case, and check that the device has battery. Headphones that are connected to another phone or laptop may stop broadcasting, so turn Bluetooth off on your other devices while you search.
Is BlueKit free?
BlueKit is free to download and scan with. BlueKit Premium unlocks sound and vibration alerts, favorites and the map view.
Does BlueKit need an account or collect my data?
No account is needed. Bluetooth scanning happens on your iPhone, and your scan results and favorites stay on your device. BlueKit uses basic app analytics and a purchase service; the privacy policy lists exactly what they receive.
