Droid does trigonometry with a slew of TI calculator emulators

ti 86 2

If the stock Android calculator isn't quite enough to fit you needs, have no fear.  App developer Doug Melton has ported the AlmostReal TI-83, TI-85, and TI-86 emulators to Android.  I've been monkeying with the TI-86 version for a few days, and have to say the job is very well done.  Support for TI-Basic is included, so hours of geek fun can be had writing those small programs many of us love to tinker with.  It even works as a calculator, too!

You can grab the TI-86 version (my personal choice) after the break, or visit Doug's AppBrain page to see the other choices, as well as a few other apps he's written.  Thanks Doug for the beta copy, and thanks everyone for sending this one in!

  • AWESOME!!! I wish they had such a thing back in my HS days.
  • Pimp...if I still needed one :)
  • TI 92 please!
  • Does this work on my Droid Captivate
  • Droid Captivate?
  • Since there is no such device, I am going to say "no it won't."
  • I wonder if the TI85 emulator does a full z80 emulation? Can I install CPM on it?
  • This. Is. Awesome.
  • i need the voyage 200 emulator :P
  • Meh, if you REALLY want to get your geek on go with Droid48 - real men use HP!
  • Can they get the ti89?
  • Seconded..... TI-89 please :-)
  • It's about damn time. I loved the ATI-83 application on my Nokia N810, and I've been waiting on this since I got my HTC Aria. I'm very happy! Thanks developers!
  • That is awesome. I spent alot of time in high school playing drug wars on my TI 82. I have to get this app after all my Droid X has a TI processor.
  • Whoa! Is this just for the OG Droid? I would love to use this in school on my Evo...now the only thing is getting my math teacher to let me use it :P
  • no app found.... wtf?
  • figured out why, you need 2.2
    i have a god damn epic with 2.1 >=@
  • I wonder how long before the author gets a Cease and Desist letter? Hmmm. Grab it while you can, folks (and backup the APK!)
  • woops, wrong post
  • From their twitter:
    "Probably won't do a TI-84 or TI-89 emulator because TI still sells those. (Also, TI-89 uses a different CPU)"
    http://twitter.com/#!/supware/status/27434614679150593 Also, does this mean we can play Phoenix?
  • Also, I must say that I dislike the title. Any freebie calculator can do trigonometry. What's special about these calculators is they can do much more than that. Features include graphing any single variable function, calculating statistics, finding roots of polynomials, do vector and matrices calculations, calculate combinatorics and probability theory, calculate with imaginary numbers, the list goes on and on...
  • I got the Ti98 emulator. I love it. It is the exact same calculator as I use in my calc 2 class. This will be nice through high school/college.
  • Incredibly LAME!!! Because Calculators had hard buttons and no touch screen, each button was locked to one or two functions. We keep seeing these Calculator emulators on newer devices and they make NO SENSE! The button functions and screen can, and should, dynamically change based on the function. Stop making these lame 1970's Calculator emulators and design a calculator based on a touch screen?

  • Looks like a good pair up with Wolfram Alpha. I'm still waiting on an android calculator with Symbolic manipulation.
  • Freaking. Wonderful. Thank you so much! My first day of class was yesterday and I have math. Of course I can't find my TI-83 so I'm glad i have this. Though I'll just use my roommate's come test time ;)
  • Jerry, please update the article to note that this app is only supported in Android 2.2 and up. Us Galaxy S owners are a becoming even more disappointed, thinking we could ditch our TI-8x's and use just our smartphones.
  • And it allows you to create programs! Reminds me of my nerdy HS days when I'd program my TI-86 all class.
  • Where did this app go?!?!?! I can't find it anymore. I had to get a replacement phone so I'm looking for this kickass app but can't find it anywhere. Aaaah.
