I just released another cool game tool app for anroid.
The Minecraft Tools features the Newsreader, which will notify you about the latest Minecraft News and sometimes free giveaways.
If you are new to the game, you should probably check the Video Fragment with a lot of Tutorial Videos. Inside the Wiki Fragment you will find a lot of detailed game information. Like all other apps, this one is for free.
Give it a try and download Minecraft Tools for android from the play store.
