So essentially this is similar to Google's rewards program and other beermoney applications like perk? Just download apps on the sotr e and get paid for doing so?
Not really. 
There are many differences: 
   1) standard currency across app stores
   2) your wallet is in the blockchain, it's not dependent of a centralised platform 
   3) possibility of p2p transfer between users 
   4) the smart contracts implement business rules: the developers receive the money directly without going through the app store
   5) as a result of the efficiency (direct transfers, no exchange rate, no banks,...) the revenue share is 85% for the developer, comparing to 70% in Google Play
