## What is Nivo?

Hang a picture straight, level a shelf, or check whether a cabinet side is plumb. Nivo turns your iPhone into a bubble level and angle finder with a large readout you can see while you work.

• Edge and Plumb — Rest your iPhone against an edge to measure its angle or check how far it is from vertical.
• Surface — Lay your iPhone face up to see the total tilt, the readings on both axes, and which way to adjust.
• Target Slope — Set the angle you want to match and choose how close the reading needs to be.
• Set Zero — Use a surface as your reference to compare the tilt of two surfaces. Guided two-position calibration helps reduce fixed sensor offset.
• Hold — Freeze a reading so you can move your iPhone and read it comfortably.
• Sound and Haptics — Get a short tone or vibration when the reading is stable and within your chosen tolerance.

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