A smart alarm clock app for Bay Area school families. The app automatically schedules alarms only on school days by syncing with official school district calendars.
- SFUSD - San Francisco Unified School District
- BUSD - Berkeley Unified School District
- Fremont USD - Fremont Unified School District
- Multi-District Support: Select your school district on first launch, change anytime from settings
- Smart School Day Detection: Automatically fetches and parses district calendars to determine school days
- Layered Override System:
- Base alarm time (applies to all school days)
- Weekly rules (e.g., "7:30 AM every Wednesday")
- One-time date overrides (e.g., "skip alarm on Dec 20")
- True System Alarms: Uses iOS 26 AlarmKit for alarms that break through DND and silent mode
- Snooze Support: 5-minute snooze for normal alarms (15 seconds in debug builds for testing)
- Custom Alarm Sounds: Bundled sounds including kid-friendly options
- Background Refresh: Automatically reschedules alarms when needed
- iOS 26.0+
- iPhone or iPad
On first launch, select your school district. The app will download that district's calendar and use it for school day detection. To change districts later, tap the district name in the top-right corner of the main screen.
- Create a base alarm: Set your default wake-up time that applies to all school days
- Add weekly rules (optional): Create or Override the base time for specific days of the week
- Add one-time overrides (optional): Create or Override alarm time for specific dates
The priority of these settings goes 3>2>1, so the highest applicable setting wins. It's also OK to not have a base alarm if you only need it for specific weekday(s) or dates.
Each district's calendar is fetched from official ICS feeds:
| District | Calendar Source |
|---|---|
| SFUSD | Google Calendar (sfusd.edu) |
| BUSD | Google Calendar (berkeley.net) |
| Fremont USD | Google Calendar (fusdk12.net) |
The app caches each district's calendar locally with per-district storage. Calendars refresh automatically when the app is opened.
