Su

Su is a non-custodial mobile app that digitizes Myanmar's traditional rotating savings groups by turning the messy reality of Viber chats, lost screenshots, and notebook errors into a clear, transparent digital ledger without ever touching or holding money. In most groups today, manual tracking leads to calculation mistakes, constant arguments over "who paid" or "who didn't," and zero accountability when someone defaults after their turn and simply joins another group, all while billions of kyats move informally each year with near-perfect discipline yet leave participants invisible to banks with no formal credit history. Su acts as Trust Infrastructure not a wallet or payment app allowing organizers to create groups, set amounts, cycles (weekly/monthly), payout orders or lottery draws (မဲနှိုက်), and invite trusted members via phone number or link; members pay the organizer directly (via KPay, Wave, cash/handover, just like real life), upload receipt proof for one-tap verification, and see the shared ledger auto-update to show who paid, who hasn't, and whose turn is next, while polite push reminders eliminate awkward debt chasing. The app quietly builds a "Su Score" in the background, tracking on-time payments, cycle completions, and reliability tied to a verified phone number. Designed specifically for Myanmar users, it offers a classic mode with big Burmese text and a minimal notebook-like interface for aunties, uncles, and neighborhood groups are clean, simple, and focused on discipline and trust, plus an optional youth layer for younger users and friends with goal tracking (motorbike, phone, trip, donation), progress bars, and toggleable badges/streaks that older users never have to see.
