Bevel: Sensor Toolbox

Bevel turns your phone's built-in sensors into a pocket workshop of measuring tools — clean, quick, and quiet. No accounts, no ads, nothing tracked, and no runtime permission prompts. It works offline; the only time it touches the network is Google Play's billing for the one-time upgrade.

BUILT HONEST
Phone sensors are handy, not laboratory instruments, so Bevel's readings are approximate — and it tells you the truth up front. Not every phone has every sensor, so each tool shows a ✓ or ✗ for your device, and the metal detector, light meter and altimeter say clearly when the hardware isn't there.
