Ruler use

There is a definite learning curve on using the app but once you get it the app works great.

Unusable because of ads

You would think app designers would figure out that you have to figure out how to learn do use the app before switching to a poker game. Took it off my phone within minutes

Forced me to buy or locked phone

I wanted a free app. This ‘locked’ my screen and wouldn’t allow me to leave without hitting ‘continue’ which point I was charged. No clear way to cancel. Going to have to waste time figuring it out.
