### 5/5 — Finally!!

*2020-08-20, version 2.9.3*

Been looking for something just like this for a long time! Works like a charm on my iPad and lots of great stuff on their website to explore too. Looking forward to seeing where this will take me.

### 1/5 — Unusable

*2015-01-24, version 1.0.2*

This app is unusable. Language says English but appears to be Dutch only. App locks to screen and will not rotate. Don't waste time. I did looking for a work solution. This is not it.
