i found on internet website that if you have idea that website approve you can receive 25% accepted ideas will get you 25% of the profits your application generates for Mobile App Fund. website http://www.mobileappfund.com
Something to always remember before you do any deals surrounding ideas: Sign a Non-disclosure agreement and a contract with proper legality. A lot of scam going around especially surrounding apps and software. Same if you ever intend to hire a freelancer to develop an app idea you have, always make sure they sign an NDA first so they don't steal your idea.
