Local-first renewal reminders

Only for iPhone

iPhone

DueSub is a lightweight, local-first reminder for everything you pay or receive on a schedule — SaaS subscriptions, domain names, VPS servers, ad revenue, team mailboxes, membership fees. Everything lives on your device. No account, no cloud sync, no analytics, no tracking, no ads. If your phone is the only device, your data is too. • Track expenses and income side by side. Monthly, quarterly, yearly, biennial, or one-off — all in one list. • Smart reminders fire 7, 3, and 1 day before the due date, plus a 9 AM reminder on the day itself. Auto-renewing items can skip reminders automatically. • Multi-currency annualized summary. DueSub converts every line to a single display currency so you can see totals at a glance. A static rate snapshot ships by default; flip on "Use live exchange rates" in Settings and the app fetches once every 24 hours from a public FX endpoint (no user data transmitted). • Home Screen widget shows your next upcoming renewals. Lock Screen widget shows the very next bill — no need to unlock. • Filter and search: active, overdue, auto-renewing, income, inactive. Search across names and notes. • JSON export and import for device migration or manual backup. Your data, your file, your storage. • Sample data seeder to demo the app without dumping your real entries. • Designed for iOS 17+. SwiftUI and SwiftData throughout. DueSub is built by one developer who got tired of surprise charges and expired domains. If you just want a clean list of what's next and a gentle nudge, this is for you. No upsell, no paywall, no account required. Just install and start typing.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

v1.3.3 Fix: After tapping "Load sample data" on the empty first-launch screen, the "Clear samples" banner at the top of the list was incorrectly hidden — it now stays visible so you can clear samples in one tap when you're done exploring. Thanks for the feedback.
