Payment app

Mockup of an idea based on me and my friends' feedback about an existing peer-to-peer payment app with a goal to minimize interaction cost:
- The most common reason for opening the app is to pay a friend (to whom we've most likely made or received a payment from the last ten transactions)
- We don't care about our friends' transactions with others (the app opened a social feed by default)
- It takes a lot of effort just to select a friend to pay (takes 9 seconds and 3 taps from app launch)
