Secant Method - App

My first app ever developed for Android.
This app will help you to determine the root of a simple function, this is very useful for Numerical Analysis.
The recognition of simple functions (i.e. F(x)=x³+2x²+10x-20=0) is working pretty well so the next step will be add support for more complex syntax.

For now is only on the Play Store, but I'll also publish it on Amazon soon.

Feedback will be appreciated.

It's development time!

I've been trying to publish some apps since a long time ago, but between the college, the college job and my current job I was not being able to take some time for my personal projects.
But finally here I am with my shinny Android developer account ready to publish some apps and games made entirely by myself.

About me... I'm a full-time developer with a lot of experience developing with Visual Studio and C#, also I have many games written in GameMaker (my second favorite IDE). So I'm kind of newbie with Android, but I'm starting to like it very much. And I am also a graphics designer enthusiast (I love "playing" with Photoshop, Blender and Bryce 3D).

So for beginning I guess this is it. I hope my future apps and games can get a place in your favorite digital library.
