Hi, I always see people giving advice in this forum on how to market your apps. I have released many apps and tried every possible method. The fact is that some apps just can't do well. Why? because that are crap! Apps and Games that are actually good and worthy of being in the top 10 will market them selves. So the Challenge here is for anyone who thinks they know a sure fire method to market an app or game. The Challenge: find and market the following free game in the app store and google play 'Tilt Universe'. Make this app popular and I will share with you 50/50 any ad revenue and the total sale price when I sell this app via an app sales website. You only win this challenge if the app reached the top 50 in US. Good luck, prove your worth!
