Stamp Hunt Brasil is an iPhone app that turns Brazilian states into a stamp collection, for people who travel within the country.
Stamp Hunt Brasil was born from a simple question: if Brazilian states do not give stamps, why not create that memory?
The challenge was keeping the game honest. That is why the app uses different kinds of evidence to grant better levels, like boarding passes with live location.
The product became less about borders and more about turning movement across Brazil into a collection people want to complete.
In practice, a trip around Brazil also leaves two familiar chores behind: too many iPhone photos and shared expenses in the group chat. GalleryCheckup helps clean up the photo library after the trip, while FastBillSplit handles restaurants, fuel, and groceries without a shared spreadsheet.
