Calculate: Advanced Calculator App Reviews

free , simple to use and with useful monitor typing like () And has very good function like sin-1 just need a graphic monitor

Ok except no RPN

This app is very usefull. if I had found this when I was a engineering student, I would not buy a calculator

This was my favorite calculator app. Now, since the update to iOS 8.3, every time I access the app it shrinks to half the size in the center of the screen. What gives????!!!!!!!

Love this calculator, but unfortunately frequently opens up shrunken to half size in each dimension under iOS 8.3. I hope Joe comes back to fix it!

Then, all will be perfect

It was good but now when I open it,its shrinks and doesnt work!!!!?

Looks like a great app, but I cant use it because I didnt update my iPhone and for operational reasons, I wont. I know its my problem, but if youre not upgraded, dont get this app.

Best scientific calculator for everyday usage on iPad or iPhone.

This is exactly what I needed to do my homework !!
