Crest Energy

Understand your daily energy rhythm by connecting Apple Health sleep data with a quick wake-up check-in.

Crest helps you understand what last night’s sleep means for today’s energy, recovery, and rhythm.

Instead of opening multiple health charts every morning, Crest brings key signals into one simple view:

• Daily energy score based on sleep context
• Sleep duration, deep sleep, REM, heart rate variability, and steps
• A quick wake-up check-in to capture how you actually feel
• 7-day averages and 14-day rhythm trends
• Private, on-device records designed for daily reflection

Crest is not a medical device and does not diagnose, treat, or prevent any condition. It is designed to help you notice patterns in your sleep and daily rhythm.
