SleepUtility: Your Personal Sleep Cycle Calculator

Ever woken up feeling like you've been hit by a truck, even after a full night's sleep? That's probably because you woke up in the middle of a deep sleep cycle. SleepUtility fixes that.

What is SleepUtility?

SleepUtility is a simple, science-backed tool that helps you time your sleep perfectly. No complicated setup, no wearables required - just practical sleep cycle calculations that actually work.

How it works

We all sleep in cycles of about 90 minutes. Each cycle takes you through different stages of sleep, from light to deep and back again. Waking up during deep sleep is what makes you feel groggy and disoriented.

SleepUtility does the math for you:

• Input when you want to wake up ? we'll tell you the best times to go to sleep
• Input when you're going to bed ? we'll suggest the optimal times to set your alarm

By timing your wake-up to match the end of a sleep cycle, you'll feel refreshed instead of dragging yourself out of bed.
