What makes it different
Native Swift on iOS 26.5+ using new Screen Time API instead of push notification spam
Money never goes through the app; fines and payments are settled between friends outside it
Fines can be anything friends agree on—pizza, coffee, beer, or money—not just currency
Transparent tab system where friends see every edit and late ticks don't erase fines
Automatic syncing with Apple Health and Health Connect eliminates manual tracking
One-day grace period to catch up on missed habits before fine is recorded
