The fifteen tools
Android
- Motion & position Compass, bubble level, gyro spin meter, and live accelerometer, gyroscope and magnetometer readouts.
- Meters Sound level meter, audio spectrum analyzer, light meter in lux, proximity tester, and a magnetic-field metal detector.
- Camera tools QR code and barcode scanner, plus a camera-based heart-rate check — for fun, not medicine.
- System utilities Flashlight with strobe and SOS, vibration tester, and a full device and sensor dashboard.
- CSV logger Record several sensors at once. Pick sources and sample rate, watch a live chart, then rename, share or export the logs.
Honest by design
Limits
Readings depend on your phone's hardware, and we say so.
These tools are meant for everyday and educational use, not certified measurement. The heart-rate tool is for fun and is not a medical device. The metal detector senses changes in the magnetic field around the phone.
Sensor readings and recordings are processed on the device and saved inside the app. They are never uploaded.
