Features & Capabilities

Sleepytime is a smart Chrome extension designed to help you determine the best times to fall asleep and wake up by leveraging natural 90-minute sleep cycles. Waking up in the middle of a sleep cycle often leaves you feeling groggy and tired, but Sleepytime calculates backward from your desired wake time to ensure you awaken refreshed and rejuvenated.

The extension requires permission to open your alarm app, enabling you to effortlessly set alarms at optimal times. Whether you're looking to improve your sleep quality or adjust your schedule for better mornings, Sleepytime provides an easy and scientifically-backed approach to better rest.

User Reviews

Sleepytime is praised for being ad-free, simple, reliable, and helpful for planning sleep and wake times. Users appreciate the clean, easy-to-navigate interface and its usefulness in organizing routines without distractions. However, several users report issues after updates, including clock/alarm crashes and instability, a clunky new UI that sacrifices ease of use, and changes to sleep cycle calculations that have reduced accuracy for some. The core value remains for long-time users, but update-related bugs and design changes are recurring complaints.

Cons
