Comments on Bubble Level, Ruler for Android

★★★★★ Teodor Hadjiev · May 21, 2017
The only app that could calibrate along all axis at once and persist this on restarts. My AFCEL sensor is off by about 2 deg. Xiaomi phones with MIUI 8. Now it levels perfectly every time. Of course the calibration (offset from system readings) is valid only in this app. Tha camera mode is perfect for me. The ruler and its calibration are a great bonus. Only the bubble mode (flat surface leveling) could get better colors and leveling is too slow.
★★★★★ Nick Lenarz · Mar 14, 2022
Extremely accurate (0.1*), calibration is easy. Biaxial bubble level is handy, but I get most use out of the vertical angle (plumb) tool. Ads are occasional and not intrusive. Well worth the purchase if you use it regularly.

★☆☆☆☆ Sammy Ellis · Oct 29, 2021
It simply does not function. All it will do is slowly reset to 0no matter how I hold it or what angle surface I hold it on. HELP. I HAVE USED THIS APP FOR A COUPLE YEARS NOW TODAY NOTHING WORKS. Yes I reloaded it, no good.
★☆☆☆☆ Benjamin Lee · Oct 13, 2024
Would you mind explaining why a level app is asking permission to take photos and videos? And why the app completely breaks if I decide I don't want my privacy invaded by a carpentry tool?
★☆☆☆☆ Nathan Moulds · Jan 18, 2017
The free version of Bubble Level (no ruler) is better. The ruler function on my phone is out of scale. Why pay for a ruler that each cm is short?
