Hi, I've just launched one month ago my flashlight application on the google store, you can find me at sparte flashlight on google store. For now I have around 1560 intalls that I mainly buyed my self with fiverr services (Yes I know, it's a TRAP). My admob made me something around 7$ and I invested something like 350$ in marketing and applications downloads. I know, it's nothing but I keep faith and started to developp other applications .For my first real I application I learned a lot and will do better for my next application. Ask me any question if you want to start in the android game.
