Find a lost Bluetooth device nearby.
Lost your AirPods, Apple Pencil, headphones or wearable somewhere nearby? BLE Detector shows the Bluetooth signals your iPhone can hear. Walk slowly and watch which signal gets stronger.
- Works with powered-on devices in Bluetooth range
- Signal strength is a clue, not a GPS location
How to search with BLE Detector
You do not need a map. You need a signal you can compare while you move.
- 01Scan
Let the app listen
Open BLE Detector and give it a moment to list the BLE signals your iPhone can receive.
- 02Choose
Pick a likely device
Use the device name and signal strength to narrow the list to the item you are looking for.
- 03Move
Follow the stronger signal
Walk slowly and compare several readings. The trend matters more than a single number.
What are you trying to find?
Start with the device. Each guide explains what can appear in a Bluetooth scan and what must be true before the search can work.
AirPods and headphones
If they are still broadcasting Bluetooth, watch how the signal changes as you walk around.
They must be powered on and within Bluetooth range.Apple Pencil
A charged Apple Pencil may appear as a nearby BLE signal that you can follow room by room.
The app cannot wake or detect a discharged Pencil.Rings and wearables
Fitness trackers and smart rings may appear while they are nearby and sending a BLE signal.
A device that has stopped broadcasting will not appear.One number matters: RSSI
RSSI is the signal strength your iPhone receives. A value closer to zero usually means a stronger signal. Walls, your body and the device itself can change the reading, so compare the trend instead of trusting one number.
Read the RSSI guideExample only. The environment and the device can change the values.
Inside the appSee the signal change as you move
The nearby view, device list, radar and settings help you compare BLE signals. Use the device name and the signal trend together.
Displayed distances are signal-based estimates, not GPS measurements.
What BLE Detector cannot do
It cannot show a remote GPS location, find a powered-off device or detect hardware that is not broadcasting Bluetooth Low Energy.
Start with a Bluetooth scan.
Open BLE Detector, choose a likely device and move slowly. A rising signal is a useful clue that you are getting closer.
