When it is paid, both sides confirm again. Done. Transparent history forever. WHY DEBTSYN • Both-sides confirmation — every debt and every payment is agreed by both people • Friendly reminders (nudges) — ping a friend politely when a debt is due • Trust score — everyone builds a 0–100 reliability score that friends can see • Group expenses — trips and dinners split Splitwise-style, settled with the fewest transfers • Private personal ledger — quick IOU notes stored only on your device, no account needed for the other person • Reports — monthly activity, balance breakdown and top partners at a glance • Pay via VietQR (Vietnam) — generate a bank-transfer QR for the exact amount; money goes bank-to-bank, never through the app SIMPLE & SAFE • Sign in with Apple or Google, or start instantly without an account • Debts sync across devices; your private ledger never leaves your phone • No ads. No tracking. Core features are free — Premium only removes usage limits DebtSyn Premium (optional subscription): unlimited friends, groups and ledger entries, more nudges and photos, watermark-free receipts.
