BiBoReward

A tablet-first gamified rewards app: kids complete challenges to earn points, grow a mascot and redeem rewards their parents approve, while violations deduct points and temporarily raise reward prices via a decaying surge. The backend is an append-only ledger — balances, levels, streaks and surge are all derived, never stored as mutable truth — so every point is auditable. One Flutter codebase ships iOS, Android and web.
