Alarm Clock & Shift Reminders

Features
Read full description

An alarm clock for days that do not repeat every week. Set an everyday or work days alarm, a cyclic alarm for shift work, a yearly birthday reminder or a countdown timer, and see every upcoming alarm in one calendar. Alarms use the iOS alarm system: they ring at the set time on the Lock Screen when the app is closed, in Silent mode and with Focus on. ALARMS FOR EVERY SCHEDULE - Quick: a one-time alarm, or one that repeats weekly on the days you pick. - Everyday: a morning alarm at the same time every day, for a steady morning routine. - Work days: set the days of your work schedule once. When your shifts move from Mon-Thu to Tue-Fri, change them in Settings and every Work days alarm follows. - Any day: pick dates on a calendar for appointments and one-off reminders. - Cyclic: repeat every few days, or every few weeks on chosen weekdays. A shift work alarm for nurses, doctors, drivers and security staff, a workout every third day or a medicine reminder. Monthly and yearly repeats and a day like "second Tuesday of the month" need PRO. - Annual: a reminder for a birthday or an anniversary every year (PRO). - Timer: a countdown alarm for a nap, cooking, meditation or a gym workout, with a Live Activity on the Lock Screen and in the Dynamic Island. WAKE-UP TASKS Give an alarm a task to solve before Dismiss unlocks in the app: - Math problem: solve an easy, medium or hard math problem. - 1-2-3: tap the numbers in the right order. The alarm has an Open button that takes you to the task. Like every iOS alarm, it can also be stopped from the alarm screen, so a task helps you wake up but does not lock the alarm. SNOOZE AND SOUND - Snooze length and number of snoozes for each alarm, with defaults for new alarms. More and longer snoozes need PRO. - Choose a ringtone from the app's alarm sounds and a label for each alarm. The volume follows your iPhone's sound settings. PLAN AND REVIEW YOUR ALARMS - Alarm calendar: a month view and a schedule of upcoming alarms. The free version shows the details of the coming days; Premium shows every day ahead. - Skip the next alarm, or tap the days to skip, without deleting the alarm. Skipping some alarm types needs PRO. - Turn off all alarms, for example on holiday. Turning them off until a chosen date and time needs PRO. - Sunrise and sunset alarms: ring at dawn, sunrise, sunset or dusk for your location, with a time offset (PRO). - Alarm history of the last 24 hours: rang, snoozed, dismissed and missed alarms. - Trash: restore an alarm you deleted by mistake. - Sort alarms by time or name, filter by type, and search alarms by name (PRO). WIDGETS AND BACKUP - Home Screen widgets for the next alarm and for the alarm list, and a Lock Screen widget for the next alarm. - Back up all alarms to a file and restore them. A daily automatic backup of the alarm list is saved in the app's folder in Files. - System, light or dark theme. FREE AND PAID Quick, Everyday, Work days, Any day, Cyclic and Timer alarms, wake-up tasks, the alarm calendar, widgets and backup are free, with ads. No ads is a one-time purchase that removes the ads. PRO unlocks the options marked PRO above and removes the ads. Premium includes everything in PRO and the full alarm calendar. PRO and Premium are available as a one-time purchase or as an auto-renewable subscription. No account is needed. Allow alarms when the app asks, so iOS can ring them on time.
