Store description excerpt
TrueLevel turns your iPhone into a precise pocket spirit level and angle logger. Lay the phone flat on a shelf, a picture frame, a table leg, or a worktop and read how level it is two ways at once: a clear bubble that drifts toward the high side, and exact pitch and roll in degrees to one decimal place. Big monospaced readouts stay readable across the room. It is a straightforward utility tool — for hanging pictures, setting shelves, checking a tripod head, leveling a washing machine or a 3D-printer bed, or just settling an argument about whether the floor really slopes. WHAT YOU GET • 2D bubble level — a bullseye vial that turns green the moment you are within tolerance. • Pitch and roll readouts — single-axis vials and precise degree numbers for each axis. • One-tap zeroing — calibrate against any reference plane and measure relative tilt from it. • Angle log (Pro) — capture a reading, give it a label like "Top shelf", and keep a tidy history. • Adjustable tolerance — choose how close to flat counts as level, from 0.2° to 2.0°. The level, readouts, zeroing and tolerance are free. TrueLevel Pro, a one-time in-app purchase, unlocks saving readings to the angle log and its history. WORKS WITH WHAT YOU HAVE • Any iPhone with the standard motion sensors. • Home Screen Widget showing your last captured angle and how many you have saved. • Live Activity on the Lock Screen and Dynamic Island for a hold-to-measure session. PRIVATE BY DESIGN No account. No cloud. No analytics, advertising, or tracking. Every reading stays on your device. Motion data is read only while the app is open and in front of you. A precise tool that fits in your pocket. ---
