Pocket Bubble Level

★★★★★ I tried a bunch of bubble level apps and this was by far the best. Good price, too (for the no ads' version of what I was using before they want $10 or a $6 yearly sub, so I decided to look elsewhere...glad I did). My only criticism is that the three dot menu is only available from "Simple Bubble Level", and from the other tools you have to hit the back button twice to return to that one to access the menu. I'd like to see it available on all tools, and to be able to set a default startup screen.

★★★★★ This level has been great and it is accurate just have to remember if you have buttons on the side of your phone case to use the other side other than that highly recommend it simple and easy

★★☆☆☆ Installed, after first use was presented with a full-screen non-closeable ad... Exited to home screen and immediately deleted!

★★☆☆☆ Accurate to within 5 degrees after multiple calibrations, flips, compares & rechecks then taking note of each reading. Usually within 2 degrees, but not at all level compared to a spirit level. Fill a jar with water. Rotate it. If it's a different reading, get another jar until both ends read the same. Simple accurate homemade level using water, air and gravity. 100% accurate.
