Handles like a TI-81-->86

:
Looks and feels the same for basic inputs. Does computer calculations but no user programmability. No graphing, but certain details of the user interface (like 2nd enter scrolls through history) are well done. Now I can see my calculations the way I want to see them and type them in the way I want to type them in. Great job!

Unique

:
I've always been a big fan of the TI-86, and it was a pure delight to find increadibly well made app. I used the 86 so much when I was in school that when I have to do a calculation now, I think in terms of how I would enter it in there, but I never have my 86 with me when I need it, so this fills the needs quite well. I just wish it had a couple functions that my real 86 had. But it's still really great.
