Align your sleep, light and inner rhythm with ease Lumiel is designed around a proven principle of circadian science: consistent sleep and light timing can meaningfully improve mood, energy, and long-term health.  By bringing clarity to your sleep, light, and activity habits, Lumiel offers warm, supportive guidance, rooted in well-established chronobiology. With beautifully designed avatars, circadian-aware metrics, and weekly reflections, Lumiel turns your data into meaningful support. These features are available with a paid Lumiel subscription. Designed for Apple Watch, and works with other wearables that sync sleep, light, and activity data to Apple Health.  Thoughtful Daily Guidance Receive a warm, personalized message each morning from the avatar you choose — shaped by your sleep, light, and rhythm patterns.  Small shifts. Gentle nudges. Better days.  Your Circadian Snapshot  See what actually matters for your rhythm at a glance:  • Sleep score & sleep insights  • Adaptive bedtime goal, updated daily  • Optional reminders, in your chosen tone  • Activity score & metrics  • Sunrise & sunset check-ins  • Outdoor light minutes  Everything essential, in one calm and intuitive view.  Unique Avatar Presences  Choose the avatar whose presence feels right for you — nurturing, enlivening, calming, or loving, with more to come.  Each avatar offers guidance and reminders in their own voice and visual style, bringing your experience to life.  Insightful Weekly Reflections  Understand your patterns more deeply with a weekly “Deeper Dive.”  Track how your sleep and light exposure shift over time, notice gentle trends, and reconnect with what helps you feel grounded and restored.  Color Themes That Feel Like Home  Your chosen avatar transforms the entire experience — colors, accents, tone, atmosphere, and mood — making Lumiel feel personal, and yours.  Why Lumiel?  Because sleep is more than hours.  Because rhythm is more than data.  Because guidance feels better when it understands you.  Lumiel brings together simplicity, beauty, and circadian science to help you return to a steadier, kinder rhythm — one day at a time.
