The calculator. Such a trivial part of smartphone software that most of us probably don't spent too much time thinking about its existence. While it can be used for the most basic functions, advanced options beyond that of the stock calculator are sometimes needed.

With that in mind, developer Xlythe yanked the stock calculator from ICS and JB and went to work. He modded it to perform advanced functions - just take a look at the feature list:

  • Addition, subtraction, multiplication, division. Really, if I broke this I'm sure you guys would find a way to give me negative stars.
  • Advanced functions like log, sin, cos and irrational numbers like pi and e.
  • Calculate complex numbers.
  • Graph X,Y Equations.
  • Matrix addition, multiplication, determinants, and eigen values.
  • Hexadecimal, Binary support
  • Displays history by pulling down from the top
  • Hide the pages you don't need
  • Tablet and Smartphone supported

Not only is it chocked full of features, but the app is completely open source. The code can be downloaded from here. The dev has also submitted the app to CM, and it should be merged into nightlies as the default calculator soon.

It's also worth noting, that since this app is based on the Android 4.0/4.1  calculator, it won't work on anything prior to ICS. If you're running 4.0 or higher, however, install away (it install alongside the stock calculator)!

    Must. Use. RPN.

  • Jays2Kings

    Sounds good to me, I have the play store version, and it gets confusing trying to figure out which is which in the app drawer.

    • duplissi

      just disable the built in one.

      • dillon s

        oh, the joys of having jellybean

  • skitchbeatz

    i wish they would mod the clock app to include the basics like a timer/stopwatch

    • Jeff B

      Euroskank nightly builds include a cherry pick of a modded clock with time/stopwatch. http://fitsnugly.euroskank.com/

      Euroskank nightlies are like pre nightly cm builds that include cherry picks of features that are being tested.

      • skitchbeatz

        SO it's coming! thanks mate

        • tanknspank

          It's been merged already. In nightlies and probably made it in to the m1 builds also.

          • skitchbeatz

            Interesting. Apparently it's in the latest nightly but I have no idea of how to access the features

          • http://twitter.com/Joecascio2000 Joseph Cascio

            From the clock app just swipe left or right.

      I also would like a world clock function, even though it's mostly a novelty.


    I'm really loving these CM tweaks to the stock apps. This is how Samsung and HTC should tweak android, not touchwiz and sense.

    • fixxmyhead

      samsung does do this but they dont include the graph. and i like touchwiz cuz of this the stock one is boring and sucks. it doesnt even include advanced things like the sin, cos, or tan etc

      • Nujad Bolivar

        Have you swiped right? All that, plus much more awaits.

        • fixxmyhead

          I clicked menu but didn't see anything. To tell u the truth I really don't remember cuz I hate stock but I think tw has more advanced features in the calculator. Anyways I barely use it do it doesn't really matter

  • Paul_Werner

    This is nice but I'll be sticking with this since it fits my needs better:


    • Leonel Macias

      thanks for the link...I've been looking for something like this

    • ari_free

      yeah that's the kind of calc that most people need on the go. But I love using my phone as a pocket mathematica with 3D plots and fractals :)

    • http://www.facebook.com/michaelgonzalez2012 Michael Gonzalez

      I bet this one would fit your needs alot better


      • Paul_Werner

        Oh I've seen this one a while back & honestly I can only think that I would want to play the baseball game on the TI-83 emulater that I used to play back in high school in study hall. Then again I could just play a full Android baseball game, so playing the old 1 would just be nostalgic more then anything

        I like the 1 I mentioned the most because of all the conversions it automatically does for me along with the tipping calc (that I use the most of all)

  • oneillperson

    Only Android 4.x compatible :(

    • fixxmyhead

      time to upgrade ur junky phone buddy

      • oneillperson

        Tell that to my 2-yr contract.
        Still, it looks like a beautiful app.

  • ari_free

    I have mathstudio. It can do all kinds of stuff and I haven't found anything more powerful but unfortunately it doesn't work well with the rest of Android.

  • Deltaechoe

    I like my ported version of TiEmu as my standard calc app, but still kudos to the dev on the new app, it looks good

    This is good to see because the stock calculator is so limited in what you can do. I do agree the RealCalc is better, but this better than the stock one Google provides.

  • Ankhwatcher

    Looking forward to that in CM10

  • http://www.facebook.com/michaelgonzalez2012 Michael Gonzalez

    Get this one.... And never need another calculator again.
    This app does everything your $100 TI-89 does


  • http://www.facebook.com/michaelgonzalez2012 Michael Gonzalez
  • you

    Wow thanks, i didn't fond how to use the graph (the equations are quite limited but it's awesome)
