Snoozo helps you wake up between sleep cycles rather than in the middle of one, so mornings feel less groggy and more rested. Tell it the hour you need to wake up, and Snoozo counts back in ninety-minute cycles, adds a short buffer to fall asleep, and shows the best time to go to bed for a full six cycles, with a five-cycle option for shorter nights.
The cycles screen explains how the counts map to hours of rest, from a short four-and-a-half-hour night up to a deep nine hours, so you can choose the target that fits your evening. Everything runs on your device with no accounts, no sign-ups and no clutter — just a quick answer when you are deciding when to turn the light off.
Sleep needs vary from person to person and night to night. Snoozo is a general well-being aid, not medical advice.
