Tired of missing events because notifications are too easy to ignore?
Unmissable turns your calendar events into real system alarms — the kind that actually wakes you up. No more silent banners. No more missed meetings. Just a real alarm with sound and vibration that demands your attention.
**How It Works**
1. Open Unmissable — your calendar events appear automatically
2. Tap any event to set a real alarm
3. That's it. The alarm fires at event time with full sound and vibration
**Real Alarms, Not Notifications**
Unmissable uses Apple's AlarmKit to schedule system-level alarms. These aren't push notifications that disappear into your notification center. They're real alarms — the same kind that wakes you up in the morning — tied directly to your calendar events.
**Works With All Your Calendars**
iCloud, Google, Outlook, Exchange — if it's on your iPhone, Unmissable sees it. Events sync automatically. No setup required.
**Apple Watch Sync**
Every alarm you set syncs to Apple Watch automatically via AlarmKit. Get alerted on your wrist even when your phone is in another room.
**Flexible Timing**
Set alarms to fire at event time, or 1, 2, or 3 minutes early so you have time to prepare. Change the offset and all your active alarms update instantly.
**Snooze Support**
Need a few more minutes? Enable the snooze button and choose how long — so you stay in control without missing the event entirely.
**Live Countdown**
See a real-time countdown to your next alarmed event, so you always know exactly how much time you have left.
**Designed for Privacy**
Your calendar data never leaves your device. No analytics. No tracking. No cloud sync. No account required. Ever.
**Simple Pricing**
- Free: 1 active alarm
- Pro: Unlimited alarms — one-time purchase, no subscription
