As an end-user of these services will I be able to identify which developers should receive my payment?

For instance if I run two apps that use their service - a game that I play every few days and a social aggregator that runs in the background all day long but that I generally I would like to define that the game is more "important" to me in terms of dollars than the app is. Perhaps the game is worth 90% of my payment and the app 5% and some random service that I tried and abandoned should get the other 5%
