I'm Mario, a student from Germany. I'm new in the Android App developer scene and hope I can find some feedback for my first developed apps here ;)
I've done two small apps at the moment. The first one is TravelBadge Germany, a geocaching app where you earn badges for visiting villages in Germany. You get experience points for every discovery and gain levels. Its perfect for tourists who travel through germany, because you get easily all infos about the town from an integrated link to wikipedia.
The other app is a small fun app based on the famous "rage guy" comics. ;)
My apps can be found here: http://www.androidpit.com/en/android/developer/823158/BlueScream
Perhaps you can give me some feedback and excuse my not so good english ;)
