Sensor Suite vs Magnetic Sensor

Sensor Suite - The Ultimate All-in-One Measurement App Looking for an app that helps you test network speed, check WiFi strength, measure heart rate, brightness, noise levels, altitude, acceleration, magnetic fields, air pressure, and more? - Sensor Suite is your go-to precision measurement tool, giving you real-time insights into your surroundings and device performance. - Network Speed Test (SpeedTest) - Measure download/upload speeds and latency. - Ping Test - Check connection latency, jitter, and packet loss. - WiFi & Bluetooth Signal Strength - Monitor signal strength and detect nearby devices. - Sound Meter (Noise Level Meter) - Measure real-time noise levels in decibels. - Heart Rate Monitor - Use the camera and flash to track your BPM with high accuracy. - Light Intensity (Lux Meter) - Measure ambient light using your camera. - Magnetometer & Barometer - Track magnetic field strength and atmospheric pressure. - Speedometer (GPS-based) - Monitor your current movement speed in real-time. - Color Detector - Pick colors from images or live camera and get RGB/HEX codes. - Device & Battery Info - Check battery health and system info - Share Data - Save results as PNG and share easily.

Magnetic Sensor turns your phone's built-in magnetometer into three precise tools: • Compass — A live, tilt-compensated compass with cardinal direction (N/E/S/W) and adjustable magnetic declination so the needle points to true north, not just magnetic north. • Metal Detector — Set a baseline reading anywhere, choose Low/Med/High sensitivity, and feel haptic pulses that get stronger as the field deviates. Perfect for finding studs in a wall, screws under drywall, or rebar in concrete. • Field Logger — Record samples at up to 60 Hz, then export to CSV via the share sheet. Saved recordings stay in the app for replay or re-export. KEY FEATURES • Live X / Y / Z axis readings + total field magnitude • Tilt-compensated heading using the accelerometer • Magnitude history sparkline + multi-channel chart • Rolling statistics: mean, standard deviation, RMS, range • Figure-8 calibration helper with quality indicator • Min / Max tracking with one-tap reset • Three sample rates: Slow (500 ms), Normal (100 ms), Fast (16 ms) • Light / Dark / System theme • English and Korean • Unit options: μT, mGauss, nT • Adjustable smoothing • Magnetic declination presets • Haptic alerts for the detector • Keep-screen-awake while recording • CSV export with full timestamp + per-axis data PRIVACY All sensor data is processed on-device and never leaves your phone. The app does not collect location, contacts, or personal information. Anonymous mobile advertising is used to keep the app free; you can watch a rewarded ad to unlock unlimited CSV sharing for the session. WHO IT'S FOR • Hobbyists exploring magnetic fields • DIYers detecting screws, studs, and rebar • Students collecting data for physics or geology projects • Hikers wanting a reliable phone compass • Anyone curious about the invisible field around them REQUIREMENTS A device with a magnetometer (most phones built since ~2013). The app cannot work on devices without one — it will tell you on launch.
