Bubble Level - Spirit Level

No adds and it automatically goes from bubble to spirit when you move your phone. It can be recalibrated or completely reset. Tested it to my spirit level and it is spot on. My only gripe would be that it's almost impossible to see the axis marking next to the readings since both the fonts and the screen is dark. Would be nice to color the fonts for the axis the same green as the bubble. So it can be seen the first time you look not the 6th or 7th time before it is noticed.

I needed a level for a simple task, and this tool saved me a lot of money at the hardware store. I tested it on a surface that I already knew was level, and it confirmed the previously known status immediately, therefore I knew I could trust it to help me level the new surface. I also love that it gives the x and y values! I am a former CAD Instructor and Engineering Designer, so I think in terms of X and Y (and Z) a LOT! Thank you for a simple-to-use app that does not collect my data!

It works but it emulates an improperly calibrated level. A level isn't worth a whole lot if I have to guess if the bubble is in the center. The out line of the bubble should line up perfectly with the circle/lines so that I KNOW that it's in the center. That said, the digital aspect of the level makes up for this. One last thing: The ruler is simply wrong. It reads about 13 inches for a dollar bill which in reality is 6.
