Level It

Level It turns your phone into a fast, accurate and beautifully simple spirit level. Whether you're hanging a picture, mounting a shelf, checking a fence post or leveling an appliance, Level It gives you a clear, instant read on exactly how level, flat or plumb any surface is — no bulky toolbox required.

Three purpose-built tools, one clean app:

BUBBLE LEVEL
A classic spirit level, reimagined. Three animated bubbles work together so you can level in any direction at a glance:
• A horizontal tube that tracks side-to-side roll (left/right tilt)
• A circular bull's-eye that reads both axes at once, so you can level a surface in two directions simultaneously
• A vertical tube that tracks front-to-back pitch
The bubbles glow green the moment you hit true level, and a live digital read-out shows your exact tilt on each axis in degrees for pinpoint accuracy.

HORIZON ANGLE
Measure the angle of any slope from horizontal — perfect for ramps, roofs, gradients, camera setups and DIY projects. A water-level style indicator stays true to the world as you tilt your phone, while the precise angle is displayed in degrees.

PLUMB
Check that posts, walls, door frames and uprights are perfectly vertical. The plumb-line tool measures deviation from true vertical, so you can straighten anything with confidence.

WHY YOU'LL LOVE IT
• Accurate — powered by your device's accelerometer with smooth, stable, jitter-free readings
• Calibrate anywhere — set a custom zero on any surface with one tap, so you can measure relative to whatever reference you like (your calibration is remembered between sessions)
• Clear digital read-out — exact degree values on every screen, not just guesswork
• Clean, easy-to-read design — a bright, high-contrast light-and-blue interface that's legible in the workshop, on the job site or around the house
• Quick to switch — jump between the Bubble Level, Horizon Angle and Plumb tools from a simple menu

PERFECT FOR
• DIY and home improvement — shelves, pictures, curtain rails, TVs
• Tradespeople and handymen — quick on-site checks
• Furniture assembly and appliance leveling

Level It is a genuinely useful everyday tool that's ready whenever you are. Download it now and never be caught without a level again.

Note: Measurement accuracy depends on your device's built-in sensors. For best results, place your phone flat against the surface you're checking and use the Calibrate option on a known-level reference.
