Transform Your Phone into a Precision Leveling Tool!
Bubble Level is the phone level and leveler app that turns your device into a professional-grade bubble level, spirit level, and inclinometer for ultra-precise leveling and angle measurement. Whether you're hanging picture frames, aligning furniture, checking construction slopes, or doing detailed DIY and carpentry work, this phone leveler gives you the accuracy and reliability normally found in dedicated tools.
With highly responsive sensor technology and optional AR measurement, you can read angles in degrees, percent grade, roof pitch, or inches per foot. Use it as a tilt meter, slope gauge, or digital level with crystal-clear visual guidance. Designed for simplicity and precision, Bubble Level gives you fast, dependable measurements anywhere you need them.
Bubble Level is designed for everyday tasks as well as precise, professional measurements. Here are two examples of how the app helps you get perfectly level results.
Place your phone on a table or countertop to confirm it’s perfectly level. The 360° bubble level and precise angle readout make it easy to spot even minor uneven spots.
Hold your phone against a wall or frame to verify perfect vertical alignment. The inclinometer mode and 0.0° plumb indicator help you hang items perfectly straight.
Use your phone as a bubble level, spirit level, inclinometer, and tilt meter in one app. Check horizontal and vertical levels, measure slopes, and verify angles in seconds.
Turn on the AR ruler and AR protractor to measure distances and angles directly in your camera view. Get clear visual feedback for layout work, DIY projects, and quick checks on site.
Bubble Level is designed as a phone level tool that’s easy to read and effortless to use on both iOS and Android. A clean, high-contrast interface keeps your focus on the angle, not the controls.
Measure angles in degrees, percent grade, roof pitch, or inches per foot. Fast one-tap calibration and smooth sensor filtering give you stable, precise readings for DIY, carpentry, and construction.
The Bubble Level app gives you precise angle measurements across multiple modes, from simple leveling to advanced inclinometer readings. You can also save a custom reference angle, making all future measurements automatically calibrated to your preferred baseline for faster, more accurate results.
Get even more accuracy with our Advanced Surface Leveling Tool. Perfect for DIY projects, woodworking, or professional alignment tasks, it uses your phone’s sensors to deliver highly reliable leveling results. Simply place your device on a surface and let the app guide you to a perfectly balanced position.
Personalize the entire look of your bubble level with fully tintable UI elements and a rich color palette. Choose the appearance that fits your environment and makes angle readings easier to see—whether you're using the inclinometer, spirit level, or any of the app’s measurement modes.

This app helps me get my iPad completely straight and level to watch when it’s on a wobbly tryone holder — never let me down yet, thanks.

More detailed measurement results than the default iOS app. Very good! Not sure what the no‑ads logo means.
