Store description excerpt
Hidden Signals combines the microphone, camera, accelerometer, and magnetometer sensors in your phone to discover invisible physical signals. The app runs entirely on the device, is free, and is ad-supported. With 15 different tools, you can analyze: AC field and electromagnetic interference (EMI) detection Noise analysis and frequency peaks Charger-related interference comparison EMI heat map Quiet/limit frequency signals Vibration detection Pipe flow signal detection Cepstrum analysis Knock analysis Pulse measurement with camera (PPG, BPM) Doppler motion detection Spirit level Compass 3-axis magnetometer Metal detector (ferromagnetic metals) Highlights: 15 tools in one application Use without internet Live graphs and real-time measurement displays Ideal for curious users, hobby projects, and field use Important note: Measurements are relative; they may vary depending on the device hardware. This application is not a calibrated scientific measuring device. The pulse device should not be used for medical diagnosis. If you'd like, I can also prepare two alternative texts, one more "marketing-focused" and one more "technical/professional".
