Great idea, however for me (Samsung ativ s aka GT-I8570) the keyboard is non functional... Too bas. Also a Ti-92 mode (landscape keyboard) would be great

I'd give it five stars but it doesn't appear to be formatted for the 1080p resolution on my nokia 1520

This is an awesome app! It is just like having a ti-89 on the phone! It was so useful to me when my ti-89 got stolen, I could still do work! The app does freeze here and there, but it is still under testing and I am grateful for the app.

Useless. Doesn't work much as it becomes non responsive. It doesn't become frozen, you can actually continue to push buttons but nothing happens. I don't even think developer is still working on further updates for this app.

This is a great way to save money so you don't have to buy a $100 and up graphing calculator.

Excellent app. Does everything my ti89 does, but on wp8. Make sure to double tap keys if program seems unresponsive, and it will register the button presses.

The app stops working after I scroll; when I press a button, the button press animation is displayed, but nothing happens. This mekes the app unusable. Please fix this.

It looks like a great app, but I haven't had the chance to see for myself. I can't download the ROM package at the beginning. Returns error NotFound. Please help.
