RK-83: Scientific Graphing Calculator Reviews

Review

Waste of a dollar. Primary fail message displays for almost every entry. Maybe the input is incorrect, but the interface is so inconvenient that I would rather do the math in my head.

Well done Robert

Shahabaaaaa

Still love this app, using it for college.

Great but where is the iphone 5 optimization?

This calculator is the best. It allows you to enter whole expressions like the TI-83 we all know and love (students anyway). Please optimize this app for iPhone 5. That is the only thing separating my rating from 5 star.

Try the standard deviation.... Want a refund!

Here's an if-then review: IF a calculator gives an output of "your mum", THEN it is dies not function as advertised. I would like a refund, and I urge the devs to either fix their program, or give me me my function money back. :( boo hiss.

Excellent App - for one-tenth the price

The graphing function is better than any other app I have seen.

Horrible

Its me you see

This app is very poorly created. When you go to "MATH" and try to work out statistic problems it solves you by replying "your mum" I think they're just stealing our money. They need to fix this or else people will be getting mad, like me.

Wont graph Y=

I downloaded this app in an attempt to avoid buying/borrowing a real ti-83 for algebra 2. I'm currently running ios 7.0.4 and I can type equations into the y= section, but when I press graph the app exits and crashes. I admire the attempted resemblance and similar button layout af a typical graphing calculator, but the fact is it didn't even graph my equations. Complete waste of my 99 cents.
