Level Tool Lite

Level Tool Lite is a clean, modern bubble level for everyday checks. Open the app to instantly see the angle of any surface, the slope as a percentage, and pitch and roll for the detail.

A large bullseye level and a tube level show where the tilt is. The app knows how you are holding the phone: lying flat it measures against the horizontal, standing on an edge it measures against the vertical, and it says which one it is doing.

Lock the measurement with Hold to read it after moving the phone, or Calibrate on a surface you know is level so the app subtracts your phone's own offset until you clear it. A short pulse tells you when a surface reads level, so you can watch the work instead of the screen.

Motion readings are processed only on your device while the app is open. They are not recorded, saved or uploaded.

Phone sensors vary between models. Results are indicative and must not be used as certified building measurements.
