Not bad

Still lacking some functionality of the TI-89. Does not graph 3d. I knew that buying this.

It does not solve or have input fields for FFTs, laplace transformation, or matrices.

The only good thing about this app is that as long as I have my phone I got a calculator. Carting around a phone I dont worry about people gonna steal my 89, but the lack of the 89 feature forces me to keep that in my bag everyday.
