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 (and any single reminder can use its own tones instead of your device's), 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. Reminder cards open a reading dialog; click a title or note body to edit its text, or add, reorder, rename, and remove checklist items there. Edit opens the full form when you need it.
- Share a reminder. Invite someone by email, including someone who has not signed up yet. Everyone with access can edit it and mark a firing done for the group. Snoozes and alarm escalation are personal, so one person's snooze does not silence another person's alert. Reminders shared with you appear in Current, Upcoming, Notes, and History as appropriate; Settings has a full Shared with me list.
- Assign a reminder. Create one for a single other person. They own its alerts and actions; you can see when each firing was handled in Assigned by me. They can decline it.
- Medication reminders. Keep a medicine name and dose with a reminder. Persistent helps you remember; it does not provide medical advice.
- 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 for managing reminders, with the same account and live data as every other surface. Browser notifications are not supported; install a native app to be alerted.
Android (recommended): install Persistent from Google Play. The app can sound alarms even while offline, and Google Play keeps it up to date. During detected phone or voice/video calls, alarms wait quietly as notifications and resume after the call if you have not handled them.
Windows: a tray app that keeps Persistent one click from the notification
area. Install it from the
Microsoft Store, which keeps it
up to date on its own. If you'd rather not install anything, the portable zip for
your architecture (x64 or ARM64) is on the
latest desktop-v* release:
unzip and run. It's for seeing and confirming reminders at your desk, and it can
keep Windows notifications present until you act, restore them after dismissal,
repeat configured nags, and loop alarm audio for Alarm reminders and escalations.
Done, Snooze, and De-escalate are available on the notification. The Store build
also provides a Windows 11 widget with the next two reminders at small size, four
compact rows at medium size, or four expanded rows at large size. It catches up
after reconnecting, but cannot reach you while it is 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.
The Android app can keep an alarm sounding until you act, even while offline. The web app manages reminders but does not send alerts. The Windows app can alert you while it is running and your PC is awake.
Setup, architecture, and the release/deploy workflow are in docs/development.md.
