It takes over half an hour to manually go through and uncheck every data tracking company that wants to track your data through this app. They technically allow you to opt out, but if you have to do each one manually and there's so many that it takes you literally half an hour, then its unreasonable for anyone to spend that long on it and they're hoping you give up. They follow the letter of the law, but certainly not the spirit.

I like the simplicity without unnecessary bells/whistles, just what i was looking for. Nice to simultaneously show inches and centimeters. However, this app only shows in landscape mode and can't flip to portrait mode. Moreover, it also locks up the phone in landscape mode and I can't get back to portrait mode unless I close this app first, which is a pain. I found a similar simple ruler app that can automatically flip between portrait and landscape, so I'll go with that one instead.

The great: it's accurate (unlike others I've tried) and it's simple. The free version works as needed. The not so great: it's really simple with no ability to customize or show increment numbers by default. Also, the 0 start is right at the screen edge and can only be indented by switching to the paid version, which I may do if this app continues to be useful to me.
