Bluetooth BLE Device Finder

Lost your earbuds again? Left your phone in a hotel room? Bluetooth Finder turns your phone into a signal detector: it scans every Bluetooth device around you, shows how far away each one is in metres, and tells you whether you are walking towards it or away from it.

No pairing. No account. No cloud. Just the signal.

━━━━━━━━━━━━━━━━━━━━

HOW IT WORKS

1. Turn on Bluetooth and allow "Nearby devices".
2. Make the lost device discoverable — earbuds in the case with the lid open, a band woken up, a tag in pairing mode.
3. Pick it from the list. Devices are sorted by signal strength, so the closest ones are on top.
4. Walk slowly and watch the distance drop.
5. Within a metre, tap Ring, Vibrate or Flash to hunt down the last few centimetres.

WHY IT ACTUALLY WORKS

Most "device scanner" apps stop at a list of nearby devices. That list tells you a device exists — not where it is.

Bluetooth Finder adds the part that matters:

• LIVE DISTANCE — a proximity readout in metres, not a vague "nearby".
• CLOSER / MOVING AWAY — the badge flips the moment you turn the wrong way, so you stop walking in circles.
• SIGNAL GRAPH — a rolling 30-second chart of signal strength. A rising line means you are closing in; a falling line means turn around.
• RING · VIBRATE · FLASH — trigger the device itself once you are within a metre.
• LAST SEEN — remembers when and where the device was last detected.

GUARD MODE

Mark the devices you cannot afford to lose — a laptop, a bag tag, your keys. Guard mode watches them in the background and alerts you when one drifts out of range.

WHAT PEOPLE USE IT FOR

• Finding earbuds that slipped under the sofa
• Checking a hotel room or rental for a left-behind device
• Locating a phone that fell between car seats
• Finding a fitness band or smart tag in the house
• Confirming a Bluetooth device is really where you think it is

WORKS WITH

Earbuds, headphones, speakers, smart watches, fitness bands, Bluetooth tags, keyboards, mice, laptops, car kits — anything that advertises over Bluetooth Low Energy.

HONEST ABOUT THE LIMITS

Bluetooth range is roughly 10–30 metres indoors and walls weaken the signal. This app reads signal strength — it cannot show a map position for a device that is out of range, and it cannot find a device whose Bluetooth is switched off. Devices that are already connected to another phone may stop advertising and become invisible. If the list looks empty, put the device back in its case and open the lid.

PRIVACY

Scan results stay on your device. No account, no sign-up, no upload. The app only asks for Bluetooth and nearby-device permissions — nothing else.
