User Reviews
This is what I was looking for. No ads, no in-app purchases, no data collected, and no data shared with third parties. I'll gladly pay a one-time, non-subscription fee in exchange for use of a tool like this. As it should be. One small ask would be a dark mode. A slightly bigger ask would be to allow us to customize colors. This app is just about perfect, thanks dev!
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.
I have been surprised how much I love this app. I don't use it everyday. But I do use it regularly. In situations where, in the past, I would have had no ruler or level available. Now that I've got a ruler & level with me all the time, it really has surprised me just how often I use it. And how nice it is to be able to get a quick and easy measurement.
Please bring the app to the same level of polish and style the free bubble level app is at. It seems to me the pro version is some kind of older version of code. Settings page still uses weird card type of visualization with some custom, non-system fonts. Also the bubble level doesn't utilize full screen estate as there's ugly white bar at the bottom. And please make the settings page available in dark mode. While functionality wise this is a good app, the polish needs work/updating.
