DueSub is a lightweight, local-first reminder for subscriptions, renewals, warranties, and recurring income — SaaS tools, domain names, VPS servers, memberships, devices, and more. Your data stays on your device by default. No account, no analytics, no tracking, and no ads. Optional private iCloud sync can be enabled in Settings for devices signed in to the same Apple ID. • Track expenses and income side by side, with weekly, monthly, quarterly, every 6 months, yearly, multi-year, one-time, and custom-day cycles. • Get local reminders 7, 3, and 1 day before the due date, plus a reminder on the due date. Reminder timing can be configured for each item. • Auto-renewing items roll forward automatically after expiration. Manual items remain overdue until you confirm completion. • Create custom categories with your own names, SF Symbols, and colors. • View multi-currency annualized totals and spending insights. Built-in static exchange rates work offline; optional live rates refresh from a public exchange-rate endpoint without sending user data. • Home Screen and Lock Screen widgets keep upcoming items visible at a glance. • Filter active, overdue, auto-renewing, income, and inactive items, or search names and notes. • Versioned JSON backup and restore preserves items and custom categories for manual migration. • Designed for iOS 17+ with SwiftUI and SwiftData. All features are free. Optional tips support development and do not unlock additional functionality.
