ℹ️ About SleepCycle

🚀 Our Mission

SleepCycle is here to help people worldwide achieve better sleep quality and wake up feeling more refreshed. We believe that the key to quality rest is not just how long we sleep, but when we wake up based on our body's natural rhythm.

🧠 90-Minute Cycle Approach

Biologically, the human brain goes through repeating sleep cycles lasting an average of 90 minutes. Waking up in the middle of deep sleep often causes grogginess and dizziness. Our tool calculates your ideal wake time right at the end of a 90-minute cycle so you wake up with optimal energy.
