Clinometer & Angle Meter
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Level surfaces, check edges and measure angles with guided calibration, preset targets, Hold and haptic feedback.
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.
