Description by Gamma Play (from Google Play)
A bubble level, spirit level or simply a spirit is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Bubble Level app is handy, accurate, simple to use and incredibly useful tool for your Android device.

A traditional modern level meter has a slightly curved glass tube which is incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. At slight inclinations the bubble travels away from the center position, which is usually marked. Bubble Level app tries to mimic the real level meter and displays the data as real level meter would.

Bubble Level app also features a bull's eye level meter which is a circular, flat-bottomed device with the liquid under a slightly convex glass face with a circle at the center. It serves to level a surface across a plane, while the tubular level only does so in the direction of the tube. Bubble Level app tries to mimic the real bull's eye level and displays the data as real bull's eye level meter would.

A bubble level is usually used in construction, carpentry and photography to determine if objects on which you're working on are level. Used properly, a bubble level can help you create flawlessly leveled pieces of furniture, help you when hanging paintings or other items on the wall, level billiard table, level table tennis table, set up a tripod for photographs, level your trailer or camper and much more. It’s a must have device for any home or apartment.

Your device should already be calibrated by the manufacturer. In case you believe it is wrongly calibrated you can recalibrate your device by opening calibration, placing your device screen facing up on a perfectly leveled surface (like the floor of your room) and press SET. Press RESET to return to your device default factory calibration.

The Angle Finder feature is particularly useful in carpentry and construction, helping you find the exact angle you need for your projects.

For digital precision, the app includes a Digital Level, offering a modern take on the traditional spirit level. Its high accuracy makes it suitable for professional-grade work in construction and carpentry.

Comments on Bubble Level for Android

★★★★★ David Rains · Aug 2, 2026
Very accurate on my current phone - very flat back and in case also with very flat back. Compared with my circle bubble and 8" bar level at 2 readings offset by 90 degrees on a tiled bathroom floored leveled with 8 foot level.
★★★★★ Bryan Gosselin · Jul 10, 2026
It's a bubble level, does what it's supposed to, haven't had any problems with it on my S22 Ultra. There's a short ad at the beginning which keeps it free, but it's not too intrusive. Thanks, devs!
★★★★★ Bolbona Toke · Nov 2, 2026
I have installed and uninstalled much water level apps and this is the only one I have found that is perfect. Now let's see how long it lasts.
★★★★★ Steve Ayers · Aug 20, 2026
Work as expected, it frees, so it has ads.🤷‍♂️
★☆☆☆☆ DJ Zephyr · Jul 5, 2026
When the first thing I see when starting your app is a full-screen ad, the next thing I'm going to do is leave a review like this. And then I'm going to uninstall your app.
★★☆☆☆ Ben Wilson · Jul 27, 2026
Used to be great, now overrun with ads constantly bogging it down.
★★☆☆☆ Joshua Burns · Jul 15, 2026
Worked great when it did but the full screen unclosable ads make it unusable.
