Sleep Calculator helps you plan sleep schedules based on the 90-minute sleep cycle concept. This approach suggests that sleeping in complete cycles may help you wake up feeling more refreshed.

HOW IT WORKS:
- Enter your desired wake-up time to get suggested bedtimes
- Enter your planned bedtime to get suggested wake-up times
- Each suggestion shows estimated sleep cycles (5-6 cycles is about 7.5-9 hours)
- Visual indicators highlight suggested time ranges

ABOUT SLEEP CYCLES:
Many people find that waking up at the end of a sleep cycle (about every 90 minutes) feels more natural than waking up mid-cycle. This app helps you explore this concept for your own sleep planning.

- People with varying work schedules
- Students managing study and sleep
- Parents coordinating family routines
- Anyone interested in exploring sleep timing

FEATURES:

- Dark mode support
- No account required

NO SUBSCRIPTIONS - NO ADS - NO DATA TRACKING
