# Description

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.

Wonderful Simple to use and perfect for anything math related you could need in school and more than that. If you really need to plot circles I would assume you use different software on the PC like GeoGebra or something. You can plot multiple graphs in different colors and find intersections. The only thing missing would be being able to input fractions as actual fractions instead of using parentheses and the division symbol but that can be overlooked. (Also no y variable)

Really good app If you need to do graphics, just put it in. It will precisely show you what you need. It has a very clean and beautiful design and it's very easy to use. The only thing that saddens me it's the fact it can't do even more. Some graphics it just can't do. But yes, definitely recommend!

Useful,but room for improvment The square root of a number has two valuse,one positive and one negative. Grapher only takes into account the positive value so when plotted it will not give the proper graph. Also, the input is basic for example a fraction has to be entered in the form of a divide sign this makes the equation harder to read. if input is familiarised and fixed square root problem will rate 5 stars

OK, but major flaws Firstly, there is the fact all equations must be equal to f(x) , excluding the possibility of drawing circles. Secondly, the intersection finder just finds the intersection on the screen, then works out the coordinates from that, making it close, but wrong. For example the solution to f(x)=x, f(x)=0 was 0.003877, 0.001912, not (0,0).

Excellent math graph app, but with some drawbacks. It's the best and simple app I've ever seen of this kind. No ads and easy to use. BUT could you add features like polar coordination system?

Khushi Selukar

Yes there's some problems but still it's good!! I started with graph's just now and I am pretty impressed as a result it is making me to like math as I can really visualize something rather than solve the equation and unfortunately mug up results !!

User reviews

Not so helpful I wanted to plot graphs for equations in 2 variables

Great! Very usefull It's a great tool, however, I feel that the lines are very hard to see, if you could just thicken the lines I would without a doubt give it 5/5

Really It really helped me a lot in solving numerical problems of quantum mechanics. So one downloading for mathematical amusement may not find it useful

Good when it works I've had to uninstall multiple times because either the axis had transformed (resulting in unreadable graphs) or completely disappeared.

Great and simple Would like 0.1 for coarse and 0.01 for fine x axis steps instead of irregular intervals. Other then this excellent app. Thanks!

Can't graph circles, other non functions You can only address x as a variable, so any equation with x and y as a binomial is off the table. Also, the visual design leaves something to be desired.

Why can't plot circle? (x+3)^2+(y+5)^2=9 is equal to y=±sqrt(9-(x-3)^2)-5, just enter 2 equation(±, so one +, and one -) and plot it, you will find the circle

Practically doesn't deserve a single start. Perhaps we could give negative feedbacks

Pretty good ! Very easy to use ,Very clear ,Fast ,No lag at all , I use this app to check the answer of the math questions . Nice work and thanks

Has an excellent interface n does everything that one wants to do with graphs!! Love it Has an easy interface, allows more than 1 graph simultaneously, has diff colours, works well n looks good 😎

Accurate graphing !! Hope it has more functions like show the min pt max pt n have better UI

Vertical lines How do I draw vertical line like X = 2 Tell me and you will get 5 stars.

Dunno how to put ² there hahahaha help HELP ME PUT x²+4 there I'm dying to know how hahahaha good app 💓

help please ! when I tried f(x) = x^(1/3) it showed the graph in first quadrant only where as it extends in the 3rd quadrant as well

Works fine Little slow on loading the keyboard when editing equations but otherwise it's great!

Thank you Dev! It's ad free and totally bugless. Must have for every student.

Nice Love it, thoe its hard to move around the graph because the graph editor pops up when you try

Overall, very good. But would've been perfect if it could also plot modulus functions and also inverse and reciprocal trigonometric functions. Thanks.

Amazing app Simple & nice app. Diffrent colour feature r great...

Hmmm! Is it me or is the graph of 1/(x (x+1)^2) incorrect?

Very good ! I recommend 100% Very good and sooo practical!Now i can verify very easily if i made my graphs right !

For sin graphs. Make it so they I can change between radians and degrees please.

It can't plot piece wise func and inequality it also show those points on the graph which doesn't exist on it
