Sunrise Alarm turns your existing HomeKit smart lights into a gradual dawn simulator — no subscription, no new hardware required. Most people see measurable improvements in morning alertness and sleep quality in as few as six days. Research in chronobiology shows why: your cortisol awakening response is triggered by light, not sound. A gradual rise from dark to bright works with your biology in a way a blaring alarm never can. Your sunrise runs directly on your Apple TV or HomePod, so it works even if your phone died or never made it home. Works with Philips Hue, Nanoleaf, LIFX, and all other HomeKit-certified devices (bulbs, strips, plugs, fans, and more). If it's in your Home app, it works. FEATURES - Customize color, brightness curves, and fade duration — the light matches your sleep environment and sensitivity - Set different alarms for weekdays, weekends, or any schedule — your body wakes consistently even when your routine isn't - Sequence lights across a room or your whole home, each joining on its own schedule — the effect builds naturally around you Your body already knows how to wake up. Now your lights do too. REQUIREMENTS - Apple Home Hub (Apple TV or HomePod) and at least one HomeKit-compatible light.
