Level Tool turns your phone into a precise spirit level and digital angle finder — no extra hardware needed. • Bubble level — lay the phone flat for a 2D bullseye bubble, or stand it against a surface for a vertical level. The ring turns green and the phone buzzes the instant you're level. • On Edge — Stand your phone on its long edge on the surface. • Digital inclinometer — read tilt and slope in real time as degrees. • No level surface needed — Put the phone down, turn it half a circle, and it works out its own error. The surface itself doesn't have to be level. • Instant feedback — clear read-outs plus haptic confirmation when a surface is perfectly aligned. • Saved — Tap Save on the Level or Angle screen to keep a reading together with its tolerance and margin of error. • Extra tools — set a relative zero, hold a reading, enable an audible level cue, and display degrees, percent slope or roof pitch. Useful for pictures, shelves, furniture and quick DIY checks. Readings depend on the phone sensors and calibration. Some of the features described require a one-time purchase.
