Must Ring
Read full descriptionHide full description
Must Ring is for the handful of things that cannot be missed — medication, picking someone up, the one task that has to happen today. Not a to-do list. Not a habit tracker. Just the few alarms that have to land, and an honest record of whether they did. RINGS THROUGH SILENT AND FOCUS Built on Apple's AlarmKit, so it rings full-screen like the system alarm — Silent on, any Focus mode, after the app is closed, after a restart. Two buttons on the Lock Screen: Done, or Snooze. IF NOBODY ANSWERS, SOMEONE GETS TOLD Set a delay. If the alarm still isn't confirmed after it, Must Ring sends a message to the contact you chose — so a missed dose doesn't pass in silence. You decide what they see. EVERY RING LEAVES A TRACE Done, done after snooze, skipped, unconfirmed, never delivered — each one is written down with its time and where you answered it (Lock Screen, widget or in the app). You can always tell "I forgot" apart from "it never rang". TEN TEMPLATES, THREE FIELDS Medication, meeting, pickup, errand, birthday, anniversary and more. Pick one, set the time, set the repeat. Lead time from 5 minutes up to a week. IN CHINA: STATUTORY WORKDAYS A work alarm can follow the official holiday calendar — it rings on make-up workdays and stays quiet on public holidays. A WIDGET THAT ANSWERS THE QUESTION What's next, how long is left, how today is going — on the Home Screen, without opening anything. PRIVATE BY DEFAULT Everything stays on your iPhone. No account, no sign-in, no server, no profiling. FREE TO START Same-day alarms always work, and so does the basic record — free, no account. A one-time purchase unlocks unlimited alarms, the template pack, escalation to a contact and full export. No subscription. Must Ring does not provide medical advice and is not a medical device. Always follow your prescriber's instructions.

Verdict
The clearest difference is update cadence: Must Ring at weekly against Printer App's monthly. Printer App's advantage is iOS requirement (14 vs 26.1). On price, ads, in-app purchases and device support there is nothing between them.
