Riyu is a simple daily budget app built around one question: How much can I spend today? Set your income, fixed expenses, and savings plan. Riyu turns the available amount into a daily budget. Unused money rolls forward, while overspending is reflected in the days ahead—so your budget adapts to real life. KEY FEATURES • Daily budget: See what you can safely spend today • Quick expense entry: Record amount, category, note, and time • Rolling balance: Carry unused budget or overspending into future days • Monthly overview: Understand spending trends and budget progress • Home Screen widget: Check today's balance without opening the app • Shortcuts: Record expenses faster • iCloud sync: Keep data in sync across your Apple devices • Shared budgets: Invite up to 5 people to manage one budget together PRIVACY FIRST Your data stays on your device and in your private iCloud database. Shared budgets use Apple CloudKit sharing. Riyu is free to download. You can explicitly start a one-month, device-local trial of core write features. The trial does not renew or charge automatically. A separate one-time in-app purchase permanently unlocks core write features. Shared-budget collaboration for the owner is an auto-renewing monthly subscription, manageable or cancellable in Apple Account subscription settings.
