Reminders that don't give up — they keep nagging until you actually mark them done.
Most reminder apps fire once and are easy to swipe away. Persistent keeps nagging — a notification that won't dismiss, or a full alarm that loops — until you actually mark it done. It's built for the things you can't afford to miss.
- It won't be ignored. Choose a persistent notification that re-sounds, or a full-screen alarm that rings continuously until you confirm — even with the phone locked.
- Escalation. If you still haven't acted, it can escalate to a louder alarm on your devices and email a chosen contact — with your covering message and what is actually overdue, so they can act on it — and you can silence that alarm without losing the reminder, so it keeps nagging quietly.
- Nothing slips through. Every firing is tracked on its own. If a reminder has several times of day, each one nags and is confirmed separately — confirming the 1:00 firing never silently clears the 9:00 one you missed.
- Works offline. The Android app schedules exact on-device alarms, so reminders fire even with no signal, and sync across your devices.
- Flexible. Remind me now with no date to pick, a one-time or repeating schedule — daily, weekdays, every N days, or monthly on the days you choose (including the last day of every month) — or never at all, for something you want to keep but never be reminded about. Multi-line notes that stay multi-line wherever you read them; custom snooze and re-nag intervals, separate tones for a reminder firing and for its follow-up nags, per-reminder notification-shade prominence (Android), and a history of what you've done.
- Checklists. A reminder can cover several things at once — a morning routine, a packing list. Tick items off as you go; each firing tracks its own ticks, so a repeating checklist starts fresh every time, and the notification lists only what you have left. Hide the ticked ones to see just what's outstanding — a long list stays collapsed the way you left it, on every device you use. Ticking everything still doesn't confirm it — only you do.
- Simple sign-in. A one-time email code, a passkey, or Sign in with Google — there is no password to forget or leak.
- Your data stays yours. No ads, no analytics, no tracking. Delete your account and everything in it from Settings, at any time; see the privacy policy.
Web: open persistent.dynamic-solutions.ca in any browser and sign up free. It installs as a web app, with best-effort reminders — same account and same live data as every other surface.
Android (recommended): download the APK from the latest release. The app is where the unmissable alarm guarantees live, and it updates itself.
Windows: a tray app that keeps Persistent one click from the notification
area. Grab the portable zip for your architecture (x64 or ARM64) from the
latest desktop-v* release — unzip
and run, nothing to install — or the MSIX if you'd rather have a proper install.
It's for seeing and confirming reminders at your desk, and it can show optional
Windows notifications with Done and Snooze on them — but it never rings an alarm
and can't reach you when it's closed or the PC is asleep.
Both apps publish into the same release list, so browsing it raw interleaves them. The Android app is tagged
vX.Y.Zand is always the one marked Latest; the Windows tray app is taggeddesktop-vX.Y.Z. The links above already filter to the right one.
Truly undismissable notifications and a looping alarm while your phone is locked are things only a native app can guarantee. The web and Windows versions are great for managing your reminders and confirming them as you go, but for the hard "you will not miss this" behavior, use the Android app.
Setup, architecture, and the release/deploy workflow are in docs/development.md.
