AllowanceKid is an allowance and chore reward ledger for families. Parents can review each child balance, record income and expenses, approve chore rewards, manage recurring allowance rules, track savings goals, and export JSON, CSV, and ZIP backups. Amounts are stored in minor units with currency codes so records can move between iOS and Android without exchange conversion. The app is designed for local-first use with no ads, no analytics SDK, no accounts, and no developer-operated server.
