Date Alarm & Shift Calendar

Specific day reminders, silent

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Alarms for a date, not just a time. They ring on silent and fill the Lock Screen. Premium: biweekly, 2nd-Friday and yearly repeats, and your next plan on the Lock Screen. Worried you’ll forget tomorrow’s shift alarm? Need reliable alerts without loud sounds? CAlarm is an alarm app for people who don't want to miss a specific day — a shift, a hospital appointment, an anniversary. You set the date and time, and it rings. The built-in iOS alarm only takes a time of day, so it cannot ring on “April 15 at 2:30 PM” alone. CAlarm can, and it shows full-screen even on the lock screen. Manage everything in one app. Add alarms to plans in the app’s calendar, and save templates for one-tap shift & alarm setup. You can also view upcoming schedules with widgets. Perfect for • Anyone who forgets to set an alarm the night before • Shift workers who don’t want to miss a work day • Biweekly trash day • Birthdays and anniversaries • Hospital and salon appointments • Concert and event dates • Anyone who misses banner notifications • Anyone who wants an alarm on a specific date Features • Date-based alarms for specific days • Full-screen alarms that ring in silent mode • Biweekly, monthly, yearly, and “3rd Thursday” repeats (Premium) • Calendar schedule management with alarms • One-tap templates for shifts & alarms • Lock screen widget for your next event (Premium) • Last-weekday and custom repeats, like “Mondays and Wednesdays every 3 weeks” (Premium) • Share plans and one-time alarms with a link • Alarm volume control • Repeat alarms by weekday • Snooze support • Heads-up notifications before an alarm • Multiple alarm sounds • Customizable theme colors • A matching app icon for your theme color • Font settings • Dark mode support • Long-press to duplicate alarms CAlarm registers alarms with Apple’s AlarmKit (iOS 26), so they ring at alarm volume even in silent mode, Focus, and Do Not Disturb, and appear full-screen on the lock screen. Works on both iPhone and iPad. Requires iOS 26.0 or later. Core features are free.
