A precise pocket spirit level and angle logger. Bubble, pitch and roll degrees, zeroing, and a saved history.
Lay your iPhone on any surface and read how level it is two ways at once: a bubble that drifts toward the high side, and exact pitch and roll in degrees. Big monospaced numbers stay readable across the room. A straightforward utility tool — for shelves, frames, tripods, appliances, or settling an argument about a sloping floor.
A 2D bubble level that turns green within your chosen tolerance, single-axis pitch and roll readouts, one-tap zeroing against any reference plane, and an angle log you can label and keep.
Zero data leaves your device. No account, no cloud, no analytics, no third-party SDKs. Motion is read only while the app is open in front of you.
