### 1/5 — Bad app

*2018-10-02*

I lost every file on the calculator.. it won’t open. I thought if I upgrade it I will have access to my files and no everything just disappeared.. lost almost everything I have this is crazy

### 1/5 — Dead App

*2018-08-05*

App non-fuctional in iOS 11.x, all menus are blank white. Support link goes to a twitter account that does not accept DMs, and has never tweeted. Dead app, inaccessible developer. Should be removed from App Store.

### 1/5 — SCAM

*2018-04-23*

Wasted $4.99 today because I typed in my password and that was it. No instructions on how the app operates or confirmation that my password was received. Now I just have at 5 dollar calculator. Don’t waste your time or money. I can’t believe apple will even allow this app to be sold
