Piece of s---


Crashes

Mikey409

Everytime I do anything it crashes. Come on really. Im using iOS 5 and have the iPhone 4 there should be no reason for crashes


No bueno

No bueno, do not get

Nothing like ti 83, if you put in an equation it can't solve it. Some greedy person is making a fortune off this piece of work


Crashes with ios5

Arthur01970

This was ok with ios4. With ios5, as soon as you click MATH and anything else, it crashes. Clicking "support" gets a "404 not found" message. I emailed over a month ago and got no reply.


I love it!

Kelisandra

It works great! I would just like to see an update that clears the input space after calculation instead of copying the previous one, and to copy the previous answer when an operation key is first pressed (like Ans+ on a ti). Aside from that I have no major complaints.


Crash w/ no support

NateHimlerbranchestown

This app crashes when trying to use the Math functions. The support page no longer exists. Don't buy.


Don't Buy

Yanike Mann

App just crashes. For real look elsewhere.


Slightly better than trash

Jlambs

Same problem as others; crashes with iOS5 when using Math functions. It won't open the Y= editor anymore either. No support to be found it seems. It still performs basic functions, but you can just use the built in calculator for that. Not worth it. Extremely dissatisfied.


No table?

-Blobfishy-

Please add a table. Also, misleading desc. Does not have all and more functions than a ti 83 calculator.


Pretty good

Good app, not much in the way of instructions
