Awesome! I used the free version for about a week without a single lockup, flaw, or problem. This calculator is incredible and I'm so glad to have it on my phone where I can carry it around anywhere. Well worth the small amount to donate! Edit: I like the button highlight in the new version!

Wow! Finally a good emulator, I rarely use my real TI 89 Titanium now. And what a great development! Even phone keyboard support now!
