True Level - Spirit Level

About this app

Smartphones make terrible levels – until now.

Because of modern camera bumps and bulky phone cases, your phone doesn’t sit truly flat. That means you can never really trust any level app to work. Until now.

True Level is a professional-grade spirit level and angle finder built from the ground up to solve this problem, turning your phone into a precision measurement tool you can actually trust.

Whether you're a contractor, woodworker, DIYer, or just hanging a picture frame, True Level delivers rock-solid, jitter-free sensor data with a suite of professional features.

What makes True Level the most reliable tool:

- Smart Case Calibration: Stop guessing. True Level features a hands-free, 2-step calibration wizard that calculates the exact physical slant of your specific phone case and camera bump, completely zeroing it out.

- Sensor-math: Built with highly optimised algorithms and custom memory management to ensure the angle measurements never flicker, jitter, or drain your battery.

Key Features:

- Bullseye & Tubular Levels: Classic X and Y axis leveling for both flat surfaces (tables, washing machines) and straight edges (picture frames, walls).

- Advanced Angle Finder: Need to measure a corner? Press the phone against the first wall, tap "Set Wall A", move to the second wall, and lock it in. True Level automatically calculates the exact inside and outside corner angles.

- Tare Zero: Working on a slope? Instantly set your current tilt to 0.0° to easily measure relative angles (perfect for matching pipe gradients or roof pitches).

- Freeze Frame: Need a measurement in a tight, awkward spot where you can't see the screen? Hit the Freeze button, pull the phone out, and read the locked data.
