COMMON QUESTIONS Does it work without an account or internet? Yes to both. Everything happens over Bluetooth on the device. What can it actually see? Any Bluetooth Low Energy device advertising nearby: name, address, RSSI, advertisement data, then the full GATT tree — services, characteristics, descriptors — with read, write and notify. Can it find my lost earbuds or a tracker? It can tell you whether they are advertising and how strong the signal is, which gets you warmer or colder as you walk. It cannot show a map or a direction: BLE gives signal strength, not bearing. Does it work with classic Bluetooth devices? No. iOS only exposes Bluetooth Low Energy to apps. Car kits and older audio devices that use classic Bluetooth are invisible to any app on the App Store. Why does the address change every few minutes? That is iOS, not the app. Apple rotates the identifier it shows you for privacy, so the same device can appear under different addresses. Does it work on iPad? Yes.

Find nearby Bluetooth devices by following live signal strength - useful when earbuds, headphones, or a speaker disappear nearby. NearFind turns your phone into a Bluetooth Low Energy (BLE) radar. Scan discoverable devices, sort by strongest signal, then walk and watch the score rise as you get closer. Proximity is estimated from RSSI - not GPS, exact metres, or direction. HOW IT WORKS 1. Open Scan and see nearby BLE advertisements. 2. Pick your device, or an unnamed BLE device. 3. Follow the radar and signal charts. 4. Use Audio Guide (Premium) - beeps get faster as you get closer. 5. Save devices for the next search. WHAT YOU GET • Fast BLE scanner with a live RSSI-based score • Strongest-signal sorting and filters • Guided radar with a live signal trend and short signal history • Premium longer signal history, proximity beeps, haptics, and advanced BLE details • Free unlimited scanning and three guided searches each day • Clear, on-device guidance for unnamed Bluetooth advertisements IMPORTANT LIMITS • Works only while a device is powered on and advertising over Bluetooth. • Proximity is estimated from signal - not GPS, exact metres, or direction. • Some devices may be unnamed if they do not advertise a name. • NearFind cannot force another device to play a sound.
