Smaller and much better version is now available with name KK2 Guide Pro and its free https://play.google.com/store/apps/details?id=com.nitramite.kk2guidepro

This is KK2 Guide and it's meant to help when you are flying in field and need basic settings information fast.
I made this app for my own use but also other's in mind. App size is tremendous due style how I made this. Please contact me if there is any issues, because this app is not ready yet and information may not be quite correct.

I just tested this app on 3/28/2015 when I flashed my KK2 firmware to newer one. I didn't have to Google basic settings, just open this app and find them out there easily including pi tuning guide.

Features
* See basic information related to KK2 menu items.
* Tutorials, like how to calibrate ESC's
* Basic first time setup and tuning guide
