Ratings and reviews

I've only used it this morning, but this app seemed to work well. There were whole screen ads that popped up during use, but I only saw 1 each time shortly after I opened the app and 1 a little later in, and do not consider that excessive. I suspect that longer minutes using at one opening, might get more ads.

Extremely easy to use and calibrate. Nice clear display. However, it does require a very level surface when calibrating. Adding the ability to average two calibration runs, with the phone rotated by 180 degrees between each run, could improve this. Overall, a great app. Thanks

It worked immediately. My coffee table is level! I'm sure when I need it, it will work just fine. FYI: Your English needs help in the description of the app. Instead of simply, just say simple. Both times. I haven't read the app instructions yet. I'll let you know if I see anything. You were close
