Nivo - Bubble Level

Use your iPhone to level a shelf, check if a surface is plumb, measure tilt on both axes, or match a target slope.

Inside the app

Features

Check an edge or surface

Rest your iPhone against an edge to measure its angle or see how far it is from vertical. Lay it face up to see total tilt, readings on both axes, and which way to adjust.

Match a target slope

Set the angle you want to match and choose a tolerance. Enable sound or haptics to get feedback when the reading is stable and within that tolerance.

Set a reference and hold a reading

Use Set Zero to compare the tilt of two surfaces. Guided two-position calibration helps reduce fixed sensor offset. Hold freezes a reading so you can move your iPhone and read it comfortably.

Work offline

Choose measurement units and keep the screen awake while you work. Nivo works offline and saves settings and calibration on your iPhone.
