Calendar alarm clock
Last updated 29 September 2026
Set a WakeSharp alarm before your first calendar event, with an earliest and latest wake time. Calendar processing stays on your device.

“Ring 90 minutes before my first meeting.” WakeSharp reads your calendar on your device, re-checks it overnight, and moves the alarm when the meeting moves. Read-only, optional, never transmitted.
How to use it
- Allow calendar access and create a smart alarm rule.
- Choose how many minutes before the event to ring, plus the earliest and latest times.
- Review the next alarm after editing your calendar. Keep a fixed backup for an appointment you cannot miss.
What to check
A shift rotation is for patterns that aren’t weekly: 4-on / 4-off from an anchor date, each phase with its own time, and a preview calendar so you can check it before you sleep on it.
