A decentralized app! If it's compatible with the most common phone carriers, then it can become popular.
An idea is to make an app available in the most popular app stores which leads to a link somewhere on InLeo, from which a native, real app can be downloaded. That way, the real app doesn't have to play by any rules imposed by those popular app stores.
Bypass the system and increase exposure!
