Works very good

### 1/5 — Not soo Clev

*2026-04-06, version 1.14.6*

This was my daily go to calculator, it worked perfectly, had smart useful features and to be honest, made the standard iPhone calculator feel rubbish. 

ClevCalc has since locked half its features I really appreciate behind a pay wall. I shouldn’t have to pay for a calculator app no matter how Clev it is. 

I will be searching for an alternative

### 4/5 — Great call ads only issue

*2026-03-19, version 1.14.6*

Great calculator.  Don’t think it’s worth the monthly cost but I’d pay for the purchased version if it was a one time purchase as opposed to a monthly fee.
