Takes forever to type in an equation. It switches back to ABC instead of staying on 123 when you type in a number. Voice at the beginning is annoying.

Works but needs paid to get the basic function such as draw a tan graph :(

Force closed on both mine and my wifes droid x's. Couldn't open at all. This is the second lite version'd graphing calculator that would not open!

Right now the app is unusable. It has potential if the developer adds to it, but its missings any tool that would name it useful.

Crap: until the sound is killed and a few other things are fixed I am uninstalling

Says 120x+1000 is an invalid equation. Then, it plots it anyway, but won't let you change any values for the viewport ranges.

Cannot recognize simple and basic linear equations, only specific axis points. Useless. Uninstall

Pretty good. To really learn Math you need to know how to do it the old fashion way and use this app only to verify - can't use this app during exam.

Very nicely done! Good equation parsing. Definitely some thought put into this one, which is proving to be a rare thing. -Wes

Kinda lame because you can't do functions with ln or integrals... even in the full version... handy calc is 100 times better... and its free

Not a bad app, per se, but HandyCalc is more versatile and intuitive to use. For example, entering equations is much easier (for me) in HC.

This app is more powerful then the 115 dollar Texas intruments calculator I had to buy for algebra 2! Does everything you could want

Great job rudi, only giving it five cuz it costs, but then again so dont calcs from the store lol

Wow, who ever made this, thanks a bunch! I didn't have enough for the stupid texas calculator... this app and arity work great together!

Great app, for square roots use x^1/2 and cube roots x^(1/3)

So useful. I like this. If possible, I would like to handle conic function.

FAQ’s

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?

A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/

Q. How do I get to the keys for pi, e, solve, etc?

A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.

Q. What do you have planned for future releases?

A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!

In the professional version it is possible to define up to 13 parameters and you can explore the graphs (coordinates, tangent, normal).

* We are testing this feature at the moment. The points were calculated numerically. That's why it is possible that not all points are found, especially with non continuously differentiable functions.

Are there any open questions? Send us an E-Mail: cassiopeia.applications@gmail.com

Why does this application need the permissions:

Internetconnection: To support the development of this app, I added advertisements to the app.

Write on external storage: To export the graphs as an PNG-file we need to write on the external storage.

Q. How do I view the Step-by-Step screen for a problem?

A. First enter the problem into the calculator and hit enter to see the result. Then click on the result. Make sure you are clicking on the result and not its input, as clicking on its input will paste the input into the current entry field. Also, Step-by-Step must be enabled in the settings when the result is calculated. By default Step-by-Step is enabled.

If you are not completely satisfied with your purchase and you email me at support@mathally.com within 14 days of your purchase, I will give you a refund. Please include your order number in the email. (Google play only gives you 15 minutes to automatically get a refund, I think this is too short). You can only request a refund once.

If you find any bugs or have questions, please email me.

The appearance of every function can be adjusted before or after it has been drawn, you can also set the order of the functions on the plane(e.g so no function covers the one you want to be on top).

Additional functionalities in current release include:

- numerical integration

- finding zeros, local extrema(maxima and minima), intersection points

- generating a function from a discrete set of points using:

- linear regression

- exponential regression

- polynomial interpolation

## Graph

Equations can be hard to read and understand. Graphs were invented to help people understand the meaning behind the formula using a regularized coordinate system. This program lets you draw graphs of math functions that you enter yourself in terms of x. Enjoy learning math for the price of a burger.
