## Description

Calendar Alarm is built for irregular wake times such as night shifts and rotating schedules. Create wake-up patterns (with a name and color), view them in a monthly calendar, and quickly link patterns to alarms by date. It runs in the background, so alarms sound even when the screen is off, and can vibrate or play in silent mode.

New feature: Automatic calls for snooze. If you miss an alarm, the app can place an automated call to wake you up. Other handy options include batch changes across linked patterns and the ability to set alarms for multiple days at once.
