## Most critical reviews (3 lowest-rated)

### 1/5 — RPN calc.

*2020-02-26, version 1.1*

Can’t turn the d__m thing off. Pretty low res device. Should be free. Half the keys don’t do anything. Developer spent more time on the call olor scheme than on coding.

### 1/5 — App swipe off my 10R screen

*2019-05-05, version 1.1*

I like this app but I can’t get it to swipe off my screen once opened in full screen.  The only way I can close the app is to shut down my phone completely. I do not know if this is me just not knowing how but I have many apps and have never had this problem with any of them.

### 4/5 — Decimal points

*2023-03-12*

Cannot change from European (,) to American (.) decimal point indicator
