Are you an engineer or an engineering student? Then a scientific calculator is a must-have for you! AlmostTI will turn your N900 into one of the Texas Instruments Sci Calcs that beat pretty much every calculator app that is available for the N900!

AlmostTI is a Texas Instruments Sci Calc emulator and a really great one! It will emulate TI73, TI82, TI83, TI83+, TI83+ SE, TI85, and TI86 (some models will require you to locate a ROM for them, as the app doesn’t include it by default) and emulate them really well, making pretty much every single function usable! Writing code, graphical calculations, anything that a real TI can do, Almost Real TI can do as well.

See for yourself, fetch the emulator from Extras with

sudo gainroot

apt-get install ati85

The only thing I found weird is the lack of documentation. It took me some time to figure out that you need to tap the top-left corner of the screen for a menu that will allow you to choose which calc to emulate. The top-right corner quits the emulator.

Totally the best calc app for the N900, and a must-have for the engineers, ATI85 is something you would really like to have on your N900. Especially since real TI-eighties don’t actually fit into a pocket.
