Plot functions and trace their graphs with ease! This is a simple graphing calculator with graphing capabilities similar to TI-83 or TI-89 calculators. To start adding equations, tap the graph! There are no ads, because I hate ads.

Features:
* Graph tracer via trackball, trackpad, d-pad(hard or soft)
** Press for current trace position
** Up/down to change functions
* Find intersection of 2 graphs
* Save graph to SD card in "My Graphs"
* Pinch-to-zoom and panning
* Full screen graphing calculator
* Custom equation keyboard
* All colors are customizable
* Long press to bring up soft d-pad (top or bottom)
* Install on external media

I would love to hear suggestions for any improvements or if you have problems using this program. Please email me if you think something is missing or if you would like to request functionality.

I am not able to respond to comments, so please send an email so I can be clear on your request.

Excellent Best app ever .. Thanks a lot

[2013-07-14] A Google User:
Love this The best i've seen. Everything works properly and the functions are displayed very comfortably. Great app, good job.

[2013-07-11] A Google User:
Nice App! Thank you for making this available and ad-free!

[2013-07-09] A Google User:
Excellent Nice app

[2013-07-05] A Google User:
Excellent No frills app, but does what it should so far. No weird permissions or anything. Thank you very much! Would be happy to donate, if the option exists somewhere.

[2013-07-02] A Google User:
Awesome

[2013-07-01] A Google User:
What I exactly need It has everything we need and great that it can plot so many graphs at once! Very user-friendly. Would be better if we can see which points we are moving through while pressing the up down left right. 5 stars if that is solved.

[2013-06-28] A Google User:
Easy to us Very comfortable and useful app. Recommend it everybody!!! 5 stars!

[2013-06-17] A Google User:
Works great Works perfect. And has no dodgy permission requirements :P thanks for this

[2013-06-15] A Google User:
Excellent 1 f d best

[2013-06-14] A Google User:
Clean and simple There are a lot of graphing calculator apps on the android market, paid and free. This one seems to be the best. It has a nice clean interface and isn't clustered with a million buttons. The program reminds me of MathGV for Windows, and runs beautifully on my nexus 7. The best part of this app is that it is ad free!

[2013-06-14] A Google User:
Stiil same problems Still problems with optical track pad when there is no equation. It says "no available equation for cursor", and this pop up message repeats even when I exit application, I have to reboot to stop it from showing. Autorotating screen even when screen rotation is turned off.

[2013-06-12] A Google User:
Nice Lot of help for my math studies. I'll give 5 stars

[2013-06-09] A Google User:
Genius! 5 stars for a great, free, no ad having app!

[2013-05-25] A Google User:
Must be the best graph drawing app Im so into it

[2013-05-25] A Google User:
Brilliant..!!! compare file size, efficency, interface and graphics... all so clean! way to go! 5 stars! *****

[2013-05-19] A Google User:
Couldn't be better!

[2013-05-17] A Google User:
Great app Really great. Excellent. 100% recommended.

[2013-04-24] A Google User:
Nice 5 stars if I could switch x and y arguments

[2013-04-21] A Google User:
Not a bad start Pretty good, but could use some improvements. Have to touch the equation editing field a second time to pull the keyboard up. Also the find intersection function didn't work...never get prompted to select the second equation. Using Droid RAZR maxx HD.

[2013-04-18] A Google User:
:) Ya know wat wud make this app effin awesome.. if it could play the graph as a sound where x is time and y is amplitude

[2013-04-09] A Google User:
Fantastic Really awesome app but it would be great if could zoom in on a single axis without the entire graph zooming in

[2013-04-07] A Google User:
Alot of help Got my homework done quick and helped me figure out the graphing

[2013-04-07] A Google User:
ok

[2013-04-01] A Google User:
Nice Thanks. Very helpful!

[2013-03-28] A Google User:
Light and accurate. Very easy to usr.

[2013-03-11] A Google User:
Easy to use Simple, easy to use, and powerful.

[2013-03-04] A Google User:
Great app Works well and is very useful, but I wish there was the option to toggle showing horizontal/vertical asymptotes

[2013-02-22] A Google User:
Hicham itani Excellent job

[2013-02-21] A Google User:
Love it Easy to use and quite accurate...

[2013-02-20] A Google User:
Great app! Love this app! Only quarrels with it are, that the trig functions are kind of, well, everywhere. Tan and sin are on one screen and cos on the next. Also, a factorial button would be great. And (wants more than needs) the ability to have non-functions, like x^2 + y^2 = 25, or x = y^2 - 5y. And a way to rescale one axis independent of the other

[2013-02-11] A Google User:
Perfect Love the no adds, it works brilliantly.

[2013-01-25] A Google User:
Great Just what I was looking for. I couldn't find how to graph on all the other apps I tried, and it was just a second calculator after my origional. This is easy to use, and if you already have a basic calculator, it is great.

[2013-01-12] A Google User:
Works like a charm Just what I was looking for. Quick and easy way to graph equations

[2013-01-09] A Google User:
Amazing very helpful

[2013-01-07] A Google User:
Perfect Only thing missing I think is the ability to set the axis scale independently by 2 finger gesture (pinch in/out on x or y). I look forward to this... ;)

[2013-01-06] A Google User:
Excellent Everything fixed works like a charm now... Thnx a lot !

[2013-01-06] A Google User:
Awesome Awesome

[2013-01-06] A Google User:
Great update Works well on my phone.

[2013-01-05] A Google User:
Epic Although my use is mainly limited on polynomial equations, it's great for revising unsolved exerciced

[2013-01-05] A Google User:
Equation editor "Equation editor" shows the keyboard and number pad at the same time...

[2013-01-01] A Google User:
excellent excellent graphics application

[2012-12-30] A Google User:
Cursor fixed with update Works great

[2012-12-30] A Google User:
Very good His program helps me enormously to understand my math classes. Its really good, but!!! It does not show horizontal asymptotes but vertical. I miss that a bit, thanks for that program anyway :)

[2012-12-30] A Google User:
Love you creator First of all, no ads... Thanks a tom for not putting up those... Secondly this app is very handy as well.. Thank you

[2012-12-27] A Google User:
awesome.. cool and helped a lot..

[2012-12-24] A Google User:
Excellent Thank you for you making this available for all

[2012-12-23] A Google User:
Works better than others It's the best one out there so far although making a table option would also improve it a lot

[2012-12-23] A Google User:
Best on the market I use this graphing tool all the time in the engineering and signals/systems training work I do. A simple yet powerful interface with flexible presentation options is all I need.

[2012-12-19] A Google User:
Excellent This app simply rocks !!

[2012-12-18] A Google User:
Ingenious!!!!!!! I really love it toooooooo much!!!!!!!!!

[2012-12-18] A Google User:
Excellent app!!!(edited) But.. Theres a chink in your armor. When i press the left bracket button, the display shows both the brackets'()' being inputted and whatever i type then gets displayed after the brackets. So everytime i press that button, i have to press DEL once,which is annoying. Otherwise its fine.

[2012-12-13] A Google User:
Keep it simple! Just what I need, free. Great thx!

[2012-12-12] A Google User:
Bug No cursor appear when typing or editing. Also the () automatically inserting is bad idea

[2012-12-12] A Google User:
Nice Definitely a five star app.

[2012-12-10] A Google User:
Excellent Quite useful and easy to use even for advanced maths graphs such as ln and trignometric etc

[2012-11-29] A Google User:
Great but not every thing It contains graph of y=f(x) only. I'm looking for app that can graph the equation.like linear,quadratic,expanantion etc..

[2012-11-29] A Google User:
Very Useful Helpful for testing out algorithms.

[2012-11-28] A Google User:
Show wrong plot for functions y=x^(1/odd#) I give it below average because it show wrong interpretation for the functions such as y=x^(1/3), y=x^(1/11). If they can solve this problem, it would be a useful app. Sony Xperia p

[2012-11-27] A Google User:
Good app this thing works like a charm. I just wish it were 3D capable

[2012-11-23] A Google User:
Great graphs Excellent little graph plotter. Does what it says on the tin. I've made a whole class download it to use on their phones in lessons.

[2012-11-18] A Google User:
Good Its nice but if i have to plot a parabola, then i have to plot two curves with +-(sqrt(4*a*x)). Would be gr8 if it had the option of plotting func wid x nd y.

[2012-11-18] A Google User:
Where is it? Please make the cursor visible when editing equations!

[2012-11-17] A Google User:
Very good app It very helped me

[2012-11-15] A Google User:
light app awesome app clean and add free

[2012-11-14] A Google User:
Incredible Absolutely love it. So easy to zoom in and out and incredibly accurate. I'd use this over any TI calculator! Maybe a min, max, zero calculator in the future? Thanks a million! -Galaxy S III

[2012-10-29] A Google User:
Needs 'Y' For circles

[2012-10-26] A Google User:
SGS3 Perfect!!! Wonderfully neat.. Exactly what i needed. Good work dev! Cheers!

[2012-10-14] A Google User:
Great app Works so great, easy to use, no adds and free! :D Good job guys.

[2012-10-07] A Google User:
About Nice app.

[2012-10-02] A Google User:
Like a boss GUYS.. TRUST ME..THIS APP DELIVERS AWESOMNESS !

[2012-09-18] A Google User:
Good job Saves LOTS of my time doing my homework, thanks! But I need the 'y'.....

[2012-09-17] A Google User:
Good for math class *****

[2012-09-16] A Google User:
Nice app Works nicely with mine so far

[2012-09-08] A Google User:
Perfect. Title says it all

[2012-09-06] A Google User:
A- Sometimes jumps/glitches around the screen. The backspace button in the equation editor only works when inputting a new equation, but not when editing. Overall a quality piece of software.

[2012-08-29] A Google User:
Good but lacks functions It doesnt have polar coordinates

[2012-08-27] A Google User:
Handy because this can handle many functions

[2012-06-10] A Google User:
Great

[2012-06-06] A Google User:
Love it No ads yeah a first

[2012-06-04] A Google User:
Useful!! :-D Amazing app.. Helps me in calculus n electrical engineering a lot.. Voltage fuction.. Fourier approximarion etc is easy to visualise... Just add max, min, zeroes.. Will be lot better! Great app!!

[2012-05-20] A Google User:
No 3d graphing Kinda sucks because i needed it for that specifically

[2012-05-17] A Google User:
Display problem Asymptotes displayed with same line weight, color, and style as functions. Impossible to tell apart from near vertical parts of function.

[2012-05-16] A Google User:
Good Simple, easy, fast, helpful. Thanx

[2012-05-04] A Google User:
Axes Good, but it could use log axes

[2012-04-27] A Google User:
Nice apps It's useful, though. Please keep the update to add more feature...

[2012-04-21] A Google User:
What the? Handy little app, but I think the acosh and asinh functions might be mixed up?

[2012-04-18] A Google User:
Very good app
