Keys are too small, some are unreadable. Unable to get the simplest graph drawn. I think the developer can fix this and I hope he/she does.

A Google User

Looks very nice, and seems to work well, but I really need a graph to plot polar functions.

A Google User

Great app, but very difficult to write a function... please little more friendly user app

A Google User

wish if the buttons were bigger otherwise the app really helps in drawing funcions... thanxxx

A Google User

Can not use calc keyboard. Is tiny and unreadable.

A Google User

The calculator is not usable. The buttons are not big enough to fit the text. Deleted until it is fixed.

Conceptul este bun, aplicaţia ar putea fi foarte utilă. Cu toate acestea, butoanele sunt prea mici pentru a putea fi utilizat, cel putin pe Galaxy S.

## GCF Calculator

This application will find the greatest common factor of any two integers. I made a better gcf app, so to the ones who say they wanted three numbers. well the new one can do six numbers, and to those who said this is force close junk. I made another one that works well, I just can't list it here because I lost the original.

I do take application requests. Feel free to contact me about anything like problems in the application and requests. I will do my best to answer your problems and requests. You guys are very important to me.

About the new permission "SuperUser":

This permission is now requested to make Total Commander work better on rooted devices. It tells the SuperUser app that Total Commander suports root functions. It has no effect if your device is not rooted. Root functions allow Total Commander to write to system folders like /system or /data. You will be warned before anything is written if the partition is write protected.
