Customer Reviews

I never write reviews...

I never write reviews... but this app just deserves it! I'm having some tough algebra classes right now.. and this calculator has been my best friend through the this hard time.... truly sublime! and if upgraded (totally worth it btw, cheaper that a scientific calculator) its unstoppable !

Again with the money

You legit have to pay to upgrade this app to use the more advanced functions, you know, the ones the calculator that comes with the iPhone can't do, which was the purpose of downloading this app. Literally pointless unless you're downloading this app purely for the aesthetics. Whoever made this app can put their head in a dumpster if they're going to keep up with the trash ideas.

Thank you!

This app is awesome. I was having a hard time using some other app. It drove me nuts having not the correct answer. Then I used this one and tested it by using the tan formula, and it works great!
