Level Tool: Spirit Level Pro

Level Tool turns your iPhone into a focused spirit level, bubble level, clinometer, and angle meter for everyday measuring.

THREE PURPOSE-BUILT MODES • Surface — check pitch and roll with a two-axis bubble level • Edge — level shelves, frames, worktops, and other straight edges • Angle — measure slopes and angles with a clear inclinometer

CALIBRATE WITH CONFIDENCE Use the guided two-position Surface calibration to compensate for small iPhone and case offsets. Recalibrate whenever you need.

TOOLS THAT STAY OUT OF THE WAY • Set a temporary Zero from any reference • Freeze a reading with Hold • Choose 0°, 45°, or 90° target presets • Get clear visual and haptic confirmation when you reach the target

PRIVATE BY DESIGN Raw motion measurements stay on your iPhone. Core measuring and calibration work offline. No account. No ads.

ONE FOCUSED TOOL Built as a precise, focused instrument instead of a cluttered toolbox.

Useful for shelves, pictures, furniture, worktops, slopes, DIY projects, and everyday alignment.
