About this app

Transform your Android device into the ultimate precision tool with Bubble Level - the go-to app for carpenters, stonemasons, and bricklayers alike. With its handy, accurate, and incredibly useful design, this app makes it easy to check if any surface is horizontal or vertical.

With three indicators, you can use any side of your phone to check surface level or plumb. Plus, the app doubles as a clinometer, giving you the inclination of any surface in degrees, percent, or inches per foot. And with sound effects that let you measure without looking at your phone, you can stay focused on the task at hand.

One of the standout features of Bubble Level is its calibration options. With relative and absolute calibration, as well as cumulative calibration, you can fine-tune your measurements for even greater accuracy. And with the ability to calibrate any side of your device independently, you'll always get the most precise readings possible.

Whether you're aligning pictures, boards, or wall mounts, calculating the inclination of pipes, or even parking your camper van, Bubble Level has got you covered. So why wait? Download the app today and start enjoying a new level of precision in all your projects!

Ratings and reviews

Was good until this last update which is no longer ad free. After the update it gives you the option to regulate the push ads but then hits you with a closed door. Either take some ads or buy the full version or it won't open at all. There are other apps like this so this one gets deleted. Face it, the accuracy of an app like this is completely dependent on your phones sensor hardware and no app is going to change the precision of the sensor chip.

This bubble level is as accurate as any similar app, and gives a handy ding when the measurement hits 0° or level. It is very flexible in giving your measurements in degrees, percents, and inches per foot, and in showing you a horizontal, vertical, and planar bubble. All this, and it doesn't waste time or space with ads! This app is perfect!

Horrible color scheme. Depending on the angle, the numbers flip to upside down. They are already too small to be read, so the app is effectively unusable. I have an earlier version of this app on an old smartphone, and the previous version is FAR better than this one. Sometimes newer is not better, and "improved" isn't always an improvement. I don't know what the developer was thinking, but he forgot the prime directive: "If it ain't broke, don't fix it."
