Tell me how will be the process of hashing on the phone?
Hi! 
There will be a pool that allocates coins to the app to reward it running the app, which comes from a pool that is the unsold coins from the ICO.
The mobile app will be getting coins other than just from the pool of unsold coins. The unsold coins are used as a bonus.
The bonus kicks in if the mobile mining calculates to make less than $30 a month. If it calculates to be more, the bonus coins unsold from the ICO will not be added in until it drops below $30 a month again.
The blockchain is powered by those mining on their home computers, so those mining on the phones dont need to use their phones resources to power the blockchain. This is why they are calling the mobile mining a "mining experience". 
There will also be an option to play the in App game to get bonus coins.
