Bubble Level Pro

A spirit level, bubble level or simply a level is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Different types of bubble levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or videographic work. Hold any of the phone's four sides against an object to test it for level or plumb, or lay it down on a flat surface for a 360° level.
● No permission required at all● No ads● Calibrate any side independently● Calibrate relatively (another object surface) or absolutely (earth gravity)● Show angle in degree, inclination in percent, roof pitch or inches per foot (:12)● Sound effects to calibrate without looking at the phone● Install on SD● Orientation locking

Useful when level tool not handy.

Where is the camera function? I bought this app hoping to use the camera function to check if my pictures are leveled on the high wall, but couldn't find the camera function as one of the screenshots implied. Other than that, it seems pretty good so far.

I paid for the PRO VERSION and did not receive it. In addition there was no sound as purported by the Developer. If you've moved the Clinometer to another App as you said, how about some directions as to where & which App so we can find it??? I'll upgrade my rating when/if these problem are rectified. Thankyou.

I don't use to that much but when do it always works great!

This has helped me numerous times. Sure I'm not a contractor where I need a level very often but in hanging pictures or leveling off the pool table or Furniture in the home adjusting the settings the washer the dryer leveled off Etc this is help drastically I love this program!

Basellined the app against my calibrated digital level, and this app is very close (+/- 1/4 degree when compared to the digital level). Solid app.

The paid version is no different. In fact the free version was MORE informative. The free version actually has a small N pointing north. The paid version doesn't have the N. There is a line but it doesn't tell you that it is actually pointing north. Also, the free version has directions on how to reset the calibration. The paid version has no hints. The free version seems to be accurate to the 100th of a degree and the paid version is less accurate. Save your money.

Disappointed. It doesn't work vertically or with the camera - despite what the description says. It's just an ad-free version of the free app. No change 21/5/20.

One of the handiest phone apps I've used. The level is very accurate, and convenient. Would definitely recommend downloading it.

Going to Pro added the light/dark option (after I said yes to the permissions for detecting Geographic North). Using the lock option for the bubble levels allows one to read angles above 45 deg. It appears the author has split the Clinometer off into a separate ad free app Request - Show the Angle Type currently in use

Clean, simple, handy, accurate! Glad to pay to support & remove ads (which actually never bothered me much).

Bry. M. Sep 11, 2020     

The free version impressed me so much i bought the app. Ads are not annoying but the level does everything i want. Helped me to grt a job done so paid for itself.

The app pics are not up to date with the real app, there is no image on the background, neither text on the controls

Phones just aren't that accurate with gyroscopes, if you rotate your phone you get a completely different value than before.

Ric. W. Apr 28, 2020     

I purchased the Pro version to get the camera part of the app to work. But found no difference to the free version.

Jam. B. Jan 2, 2022     

Works well, is easy to use, and provides a very useful tool. I was happy to pay for the ad-free pro version.

Handy and useful app for quick read when leveling something. In many cases the app is all that it's needed.

Spirit level in your pocket. Used it to build 3 custom motorcycles. No glitches, perfect!

Sha. B. Apr 1, 2019     

I've been using this app since 2012 and I love it! Always have my phone on me and it's so easy to just pull up and use! Haven't figured out how to use it with my camera but rarely require something like that anyway

mik. s. Dec 15, 2021     

Purchased it goes well. How do you calibrate it, or is that not needed?

Don. P. Feb 25, 2019     

Use it all the time. Eent up to the pro to get rid of the adds. Well worth it. Thanks.

Wil. P. Apr 11, 2021     

As advertised. The angle numbers closely agree with my dedicated electronic protractor used for knife sharpening.

Jef. K. Jan 31, 2021     

One of the coolest applications out there! Simple, light, and accurate. Couldn't ask for more.

Leo. S. Aug 7, 2020     

Excellent application. Works at any angle and direction. Love it!

Pat. H. Aug 14, 2019     

I use this app quite often. As long as it is calibrated before each use, it works well.

Deb. F. Jun 20, 2021     

Needed it for a job. Works great. I love the bell sound.

Juh. A. Mar 9, 2021     

Android 11. The "visual" (button ikon is missing) option is not found. Change between angle in degree, inclination in percent, roof pitch or inches per foot in the clinometer does not work. The sensitivity adjusting is mysterious, I don't undertand it at all. On my phone this app doesn't match the Play store presentation.

Jim. P. Aug 2, 2020     

Simple to use and clear to read . I like the ding at zero degrees as well

Joh. B. Dec 27, 2018     

The developer took out the clinometer function right after I paid for the app, specifically why I bought it.

I love this app. When I don't always have access to my tools I can always use my phone and this app.
