A graphing calculator is a college student’s best friend. Texas Instruments makes the go-to standard TI-series that is so popular, but they cost a ton. Not every student has $80 they can throw at a fancy adding machine. If you need the functionality of a TI-89, but it’s price tag places it out of your reach, you may be able to use your Android phone as a stand in.
Osas Obaiza, a contributor for WonderHowTo, described in a recent article how you could turn your phone into a full-featured TI-89. All you need is an emulator from the Play store called Graph 89 Free and a ROM offered directly from Texas Instruments. Transfer the ROM to your SD card, set it up in the emulator and you’re good to go. Check out 1.25 in this YouTube video uploaded by OfficialSoftModder for a look at the emulated calculator in action.
