Apple IAP and Marketplace Currency
How Apple’s pricing works for digital goods and designing the Touchgram Currency within those constraints.
Coming soon for Touchgram is one of the most important features of the app — the marketplace where you can buy and sell digital goods. These range from single images or sounds all the way to fully-composed greeting cards just waiting for you to customise.
We have to sell those using Apple’s In-App Purchase (IAP) system.
