Why it's built this way
Apps like this have come and gone. The ones people kept had a wait before the reveal. The ones that stumbled pushed people to invite their contacts, or ran out of money storing everyone's photos. Durpin keeps the first and avoids the rest.
- The wait is the point.
- The server holds every shot until it develops, so nobody can peek, not even with a modified app.
- Invites are a favor, not a toll.
- You never have to invite anyone to use it. You get five open invites, and they come back when friends join.
- One card per friend.
- Someone who shoots all 27 doesn't bury someone who shot two. Each friend's day is one card.
- Built to stay cheap.
- It runs on one small server at home. Every photo has a size budget, and the film look is made on your phone.
