Great converter-could use a diameter to circumference converter.
★☆☆☆☆Donovan· Mar 21, 2022
I would give it 5 stars but the main unit I need to convert isn't available. I can't figure out how to convert currency on the app. Or that feature didn't come included with my app. And Yes, I bought the pro version for $2 and some change. If I can figure this out, this app will be 5 stars easy.
★☆☆☆☆Extreme Tech· Oct 14, 2023
The app shuts down if you don't give it a rating so here's your freaking Rating. The problem is I am also a coder programmer, and I know a purpose built code when I see it every time The admittedly good app... ASKS Me the Customer to Rate it IF I DO NOT AGREE TO RATE THE APP IT CLOSES NOT I REPEAT NOT A CRASH ! 🤔 WHAT ELSE ARE YOU PEOPLE CAPABLE OF TAKING ?
