Description
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.

Very clear display; with both bubble, levels and digital indication, made it much easier to level a telescope mount, compared to using standard physical level. Acceptable level of advertising banners.

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.

05/2017: This app is great. I didn't have a level tool and needed to hang a rack in my bathroom. Excellent and handy! Update: 06/2026... Still pretty accurate for just an app.
★★★★★Mar In the UK· Jul 24, 2026
It does its work. And it does it well. Also, the ads are easy to get rid of.
★☆☆☆☆Mzale Yao· May 13, 2026
All I get is unskippable adds that runs for 3 minutes and then doesn't go away until 10 minutes.
★★☆☆☆Joshua Burns· Jul 15, 2026
Worked great when it did but the full screen unclosable ads make it unusable.
★★☆☆☆Ben Wilson· Jul 27, 2026
Used to be great, now overrun with ads constantly bogging it down.
★☆☆☆☆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.
