Many of you surely remember (and may even still use) the TI-83 as being the calculator of choice for high school and college math and science courses. Conveniently, this app is a fully-functional emulator, meaning it can differentiate, integrate, and plot functions all day and night. I must admit, it was rather strange seeing the identical (yet miniaturized) display on my phone’s screen.

Because of the sophistication and power of the original TI-83, this Android app will easily replace any other calculator app you may have installed on your phone. Basic addition and subtraction is as easy as graphing logarithmic functions or calculating arcsine.

What really sets this app apart is the ability to write TI-BASIC programs or save textual notes. I didn’t try to port any of the original games I have on my TI-83+, but it would be incredible to have an easy way to do this. Blockdude or Bust a Move anyone?


  • Fully-functional TI-83 graphing calculator emulator
  • Ability to create and run programs as you could on the original TI-83
  • Exact replica of the TI-83 interface, which is not only functional but evokes that feeling of nostalgia

Areas for Improvement:

  • Relatively small size and close proximity of buttons makes input prone to error
  • Option to toggle button haptic feedback

Conclusion: The one and only Android calculator app you’ll need because it does it all!

  1. isn’t it funny that the first thing anyone thinks of when they see this isn’t math, but games!

  2. Awsome dude, ty very much. It’s really useful to have a calculator with this quality in the smartphone.

  3. True, but it gets very useful when you are going to do a math exercise and you remember: Oh, shit, i forget the calculator…

  4. AWESOME!!! Did not know this existed, thanks!

  5. Hi, I own an Epic 4G and this app does not seem to be in my market. Anyone know anything about this?

  6. Get “bar code scanner”, scan the “bar code” posted in the end of the post and it will send you to market.

  7. This is a very useful app.

    It could be improved however by having the calculator’s off button exit the app.

  8. The Haptic Feedback can be disabled in the Options, so there’s even less of a reason not to download this.

  9. Doh!
