Is Cronk a subscription?
No. Cronk Unlimited is a one-time purchase that lifts the 5-reminder limit. It never renews, and there are no ads. iCloud sync is free for everyone.

Cronk — the reminder that never forgets.
Recurring reminders for everything that doesn't fit a calendar — medication, plants, filters, oil changes — on whatever rhythm real life actually needs.
Set a task once — every 8 hours, every 3 days, every 6 months — and Coco the crow keeps track. Coco nudges you until it's done, then quietly schedules the next one and logs the completion so you can prove you did it.

Cronk is free for up to 5 reminders with every feature included. Cronk Unlimited is a single one-time purchase — never a subscription, never ads.
Reminders that work like real life
Calendars are for appointments. Cronk is for rhythms: things that repeat every N hours, days, weeks, months, or years — the kind Apple Reminders can't schedule and to-do apps forget to nag you about.
When you complete a task, the next reminder is scheduled one full interval from that moment — the way medication, maintenance, and routines actually work. And if you ignore a reminder, Coco doesn't give up: follow-ups escalate for four hours, then a single daily nudge continues for up to 14 days.
On your device. No accounts, no servers.
Everything you type into Cronk stays on your iPhone. iCloud sync is free for everyone
and runs through your own private iCloud — we never see your data.

Privacy approach
Cronk has no user accounts and operates no servers. The principles are simple: your reminders are yours, and the little we measure is anonymous.
- Reminders, notes, and history are stored on your device.
- iCloud sync — free for everyone — uses your private iCloud database, inaccessible to us.
- A handful of anonymous usage signals (via privacy-focused TelemetryDeck) — never reminder content, never tracking, no advertising identifiers.
- Payments are processed entirely by Apple; we never see payment details.
The full details are in the privacy policy.
Common questions
What does the free plan include?
Up to 5 reminders with every feature — escalation, history, all intervals, widgets, Siri, and iCloud sync. Nothing is crippled; only the count is limited.
What if I complete something late?
The next reminder stays anchored to your original rhythm. Complete early (with a confirmation) and Cronk re-anchors from today — matching what actually happened.
Will reminders break through Focus?
Due and escalation notifications are Time Sensitive, so a 9 PM medication reminder arrives even during Sleep Focus. You can turn this off in iOS Settings.
Where does my data live?
On your device — and, if you are signed in to iCloud, in your own private iCloud. No accounts, no servers, nothing we can read.
