CronPing

Schedule repeating alarms using cron expressions or a visual builder. CronPing lets you set alarms that fire on complex schedules — every weekday at 9 AM, every 15 minutes, the 1st and 15th of each month, or any schedule a crontab can express.

Features:

• Visual schedule builder or raw crontab input
• Multiple chime sounds with optional repeat/snooze
• Apple Shortcuts integration for automation
• Alarm descriptions to remember what each alert is for
