# 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 !!
