Android Sensors

Your phone has sensors most apps never touch. Android Sensors puts all of them to work.

Four professional tools. One app. No ads. No subscriptions.

🔍 METAL DETECTOR

Point and scan. A sonar radar sweeps in real time, with a signal bar that shifts from cyan to red as magnetic intensity rises. Simple mode shows deviation from your calibrated baseline — great for finding hidden pipes, wall studs, or buried metal. Raw mode displays the full magnetic field strength in µTesla for deeper analysis. Auto-calibrates on launch; one tap to recalibrate any time.

⚖️ GRAVITY METER

A live 3D sphere tilts and rotates with your phone, showing how gravitational force is split across X, Y, and Z axes in m/s². An oscilloscope traces the signal history in real time, and the app automatically identifies your orientation — portrait, landscape, face up, face down. Total G-force magnitude is always on screen.

📐 BUBBLE LEVEL

Three sensitivity modes — Precision (±0.5°), Standard (±2°), Rough (±5°) — so you dial in the accuracy the job actually needs. The target reticle turns green and sends a haptic pulse the moment the surface is level. Pitch and roll angles are shown as live HUD cards. Precise enough for carpentry; simple enough for hanging a picture frame.

🪐 SPACE BALL

Tilt your phone and a glowing ball rolls across the screen, driven by real gravity sensor data — velocity, friction, edge bouncing with dampening. Drag and flick to throw it. Sparkle particles burst on impact, haptic feedback pulses through your hand, and 80 background stars drift in parallax behind it all. The most intuitive way to feel what a gravity sensor actually does.
