Stop searching. Start finding.

FindMyBlue helps you locate any Bluetooth Low Energy device using audio-guided tracking and a real-time signal heatmap. Walk toward the beep, higher pitch means closer.

Features

• Audio guidance — Pitch rises as you get closer, drops as you move away. • Warmer / colder feedback — Instant trend cues tell you which way to walk. • Live signal heatmap — Walk a room and watch the map build. Green is strongest signal, red is weakest. • Works with any BLE device — Fitbit, smart watches, headphones, fitness trackers, smart mugs, smart home gear, and more. • Per-device calibration for better accuracy. • Advanced mode — UUIDs, raw dBm, sort options, and the full diagnostic map for power users.
