Your sleep schedule is off. Phase shifts it back — one day at a time. Phase is a guided program that fixes your broken sleep schedule through small, progressive daily shifts. No vague advice. No endless tracking. Just a clear plan that moves your bedtime and wake time closer to your goal — 15 minutes at a time. Tell Phase when you currently sleep, when you want to sleep, and it builds a personalized day-by-day plan to get you there. HOW IT WORKS - Pick a program that fits your situation - Set your current and goal sleep times - Get a personalized day-by-day schedule - Follow science-backed daily nudges - Watch your sleep shift into place 6 SLEEP PROGRAMS Phase is not one-size-fits-all. Pick the program that matches your situation: - Sleep Schedule Reset — the original 14-day phase shift - Night Owl Fix — stop going to bed at 3 AM - Jet Lag Recovery — get back on local time fast - Weekend Drift Reset — fix the Sunday-night-to-Monday-morning gap - Shift Work Transition — adjust to a new work schedule - Early Riser Challenge — become a morning person in two weeks YOUR DAILY NUDGES Every day, Phase gives you timed nudges based on your schedule and your local sunrise and sunset: - Morning Light — get sunlight early to reset your internal clock - Caffeine Cutoff — stop caffeine at the right time so it does not interfere with sleep - Screen Dim — reduce blue light before bed to protect melatonin - Wind Down — start your pre-sleep routine at the right moment - Bedtime — hit the pillow at your new target time All nudge times adjust automatically as your schedule shifts forward each day. Toggle nudges on or off and fine-tune timing to fit your life. WIDGETS AND LIVE ACTIVITY - Home Screen and Lock Screen widgets for sun position, nudge checklist, bedtime countdown, and sleep stats - Bedtime Live Activity — a countdown on your Lock Screen and Dynamic Island as bedtime approaches - Bedtime alarm that rings through Silent Mode and Do Not Disturb WHAT MAKES PHASE DIFFERENT - A real program, not a tracker — a clear plan with a finish line - Location-aware — nudge times sync with your actual sunrise and sunset - Works offline — no account, no login, no cloud - Science-backed — based on circadian rhythm research - Beautiful Sun Arc — a visual map of your day showing light, nudges, and targets - Schedule exceptions — have an early flight? Adjust one day without breaking your plan - Takes 30 seconds to set up TRACK YOUR PROGRESS See your journey laid out. Check off each day. Build streaks. Get encouragement when you need it. Know exactly how far you have come and how close you are to your goal. HEALTHKIT INTEGRATION Phase reads your sleep, sunlight, exercise, and caffeine data from Apple Health to auto-verify nudges and show activity bars on your daily timeline. Phase never writes to HealthKit — your data stays yours. BUILT FOR FOCUS No charts. No dashboards. No social features. Phase does one thing and does it well — it fixes your sleep schedule. Your body has a clock. Phase helps you reset it. Terms of Use: https://www.theblackholecompany.com/termsConditions.html

Light in the morning. Wind down at night. CivilDusk times the two habits sleep science agrees on - from your own wake time, with no account, no ads, and no sleep score. YOUR RHYTHM, THREE MOMENTS - Wake: set it once, or let it follow your recent sleep from Apple Health. Everything else is timed from it. - Morning Light: 10 to 30 bright minutes soon after waking anchors your energy and tonight's sleepiness. Get a gentle nudge, or run it hands-off. - Wind-Down: a calm evening window - dim, wind down, bed - built from your target sleep and shown as an estimate, never a measurement. A REAL WAKE-UP SEQUENCE - Sunrise light that ramps up and ends at your wake time. - A real alarm at the top - snooze or slide to stop, like the Clock app. - Edit the order and degree: ramp length, peak brightness, alarm on or off. WORKS WITH YOUR LIGHTS - Wi-Fi bulbs, including older bulbs that never worked with a smart-home hub - scan your network and control them directly. No bulb account, no cloud. - HomeKit and Matter lights run the schedule automatically on your home hub while you sleep, no app open. - Manual control too: on and off, brightness, color - with recommended morning and evening colors. ON YOUR LOCK SCREEN - Timers run as Live Activities on the Lock Screen and Dynamic Island, with a stop button right there. - Start Morning Light or Wind-Down with Siri and Shortcuts. PRIVATE BY DESIGN - No account. No ads. No sleep score. - Nothing about you leaves your phone. Health sleep data is read-only and optional. - The only networking is local control of your own lights. CivilDusk is free. It shows estimates based on your schedule - it does not measure or diagnose anything, and it is not a medical device.
