Sleep rhythm & daily 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.

Crest 1.1.2 makes your daily rhythm easier to understand. - Today now focuses on your state type and next action, not just a score. - Sleep Summary now explains what your sleep amount, recovery depth, and body baseline mean. - Tonight target adapts as Crest learns from your recent sleep and wake-up check-ins. - Tonight target avoids overly precise bedtime suggestions while Crest is still learning. - Analysis now shows 14-day calibration progress and a clearer personal rhythm preview. - History adds a monthly rhythm view and keeps older records grouped by month. - Step context now uses the previous wake window instead of a simple calendar-day reference. - Morning reminders can be enabled after enough check-ins, and the reminder time can be adjusted in Settings. - Manual sleep duration and wake-up ratings can be added or edited from History.
