CalAlarm · Custom Dates — Apple's built-in Clock can only repeat daily or weekly; it can't ring on scattered specific dates like "the 1st and 15th of each month." CalAlarm · Custom Dates is built for shift workers — alternating weeks (every-other-week schedule), rotating shifts, split shifts, day/night shifts that change constantly. Just check any specific dates on one alarm, and it still rings full-screen even when your phone is silent or in Do Not Disturb. Powered by iOS 26 system-level AlarmKit, so it never misses a ring even after the app is closed. 【What the built-in alarm can't do, CalAlarm · Custom Dates can】 · Batch-set specific dates: one alarm can cover any number of dates (e.g. the 1st and 15th, or next Wed & Fri) — no daily repeat required. · One-tap bulk scheduling: tick an entire upcoming month or a full year of weekdays, weekends, or all dates in a single tap — schedule a year of alarms in seconds. Alternating weeks, rotating/split shifts, irregular days off — even the most unpredictable routine is handled with ease. · Rings in Silent & DND: when your phone is muted or in Do Not Disturb, the alarm still takes over the Lock Screen full-screen — you'll never miss it quietly. · Calendar View: swipe through months; dates with an alarm are highlighted, tap to see what time it rings — which days have alarms is clear at a glance. 【More handy features】 · Custom ringtones: import any audio from the Files app or system Share sheet as your tone (auto-trimmed & looped); rings on time even with the app closed. · Temporary alarm: one-off reminder (15/30/60 min later) that deletes itself after ringing — no clutter in your daily list. · Snooze limit: cap the number of snoozes to beat the habit of oversleeping. · Home screen widgets: small/medium/large sizes show your next alarm and countdown at a glance — no need to open the app. 【Privacy First】 · No sign-up, no login — just open and use. · Collects and uploads zero personal data; all alarms stay on your device only. · No ads, no third-party tracking — a clean experience. 【Free & Pro】 Core features are free forever: up to 5 alarms, single-date alarms, custom ringtones, temporary alarms, snooze, widgets, and calendar view. Pro membership unlocks "multi-date ringing" and "unlimited alarms" (one alarm can have multiple ring dates, no limit on alarm count). New users get a 14-day free trial; auto-renews afterward, cancel anytime in Settings → Apple ID → Subscriptions. Important: This app is built on system alarm capabilities. We recommend testing your alarm setup before important events, and keeping your device charged and out of Airplane Mode. The developer is not liable for missed alarms caused by device failure or system settings. Download CalAlarm · Custom Dates now and take control — pick the dates, and it rings.
