Coaching that adapts to your reality. Loopday is a personal trainer that adapts to your real life. It builds your workouts around the time you actually have, the energy you woke up with, and the equipment in front of you, at home, at the gym, or anywhere in between. No rigid programs. No guilt for the days that don't go to plan. Just the right session for today, already decided for you. Here's what makes Loopday different: - **Plans that fit your day:** Tell Loopday your goal and it builds a routine around your schedule, not someone else's ideal week. - **Adapts on the spot:** Short on time, low on energy, only have a pair of dumbbells? Loopday reshapes the session in seconds. - **No decision fatigue:** Open the app and your workout is ready. Nothing to plan, nothing to figure out. - **Forgives the messy weeks:** Miss a day or cut one short and Loopday just adjusts. No streak to break, no catching up. - **Works with Apple Health:** Loopday reads your activity and recovery so it knows when to push and when to ease off. Whether you have a full gym or ten minutes and a living room floor, Loopday meets you where your day actually is.

About

Circadian Reset

Features
Read full description

Dawn is the circadian rhythm reset companion - shift your body clock using scientifically timed interventions: morning bright light exposure, evening light avoidance, low-dose melatonin, and consistent meal timing. The personalized protocol calculates exactly WHEN to apply each intervention based on your current sleep-wake pattern and target schedule. THE TIMING PROBLEM Bright light in the morning advances your clock (makes you sleepy earlier). Bright light in the evening delays it (makes you sleepy later). The same intervention at the wrong time does the opposite of what you want. Without timing guidance, "just waking up at 6 AM" causes sleep deprivation, not circadian adjustment. Dawn gives you the timing. YOUR PERSONALIZED PROTOCOL Complete a short circadian assessment - enter your current natural bedtime, wake time, and target schedule. Dawn generates a day-by-day protocol: which morning to get light exposure, when to dim your lights, when to take low-dose melatonin (0.5mg - the evidence-based chronobiotic dose, not the 10mg sedation dose sold at pharmacies). WHAT DAWN INCLUDES (FREE) - Circadian phase assessment: find out where your body clock currently is - Daily protocol schedule: timed interventions for every day of your reset - Sleep log: track bedtime, wake time, light adherence, melatonin timing - Morning light tracking: the single most important intervention, tracked daily - Melatonin timing guide: the 0.5mg truth that most apps get wrong - Protocol science: plain-English explanations of WHY each intervention works DAWN PRO - THE COMPLETE TOOLKIT - Sleep-wake trend charts: visualize your bedtime shifting toward the target day by day - Jet lag protocol generator: input origin timezone, destination, travel date - get a day-by-day pre-flight and arrival protocol for any timezone pair - Light adherence analytics: track your morning light streak, quality patterns, and protocol compliance - AI Circadian Coach: ask questions about your specific schedule, jet lag, shift work, or any circadian challenge - powered by Grok THE SCIENCE Your suprachiasmatic nucleus (SCN) - a cluster of 20,000 neurons behind your eyes - controls every biological process on a 24-hour rhythm. It is set by light, melatonin, and meal timing. Dawn applies the same interventions used in chronobiology research: photic entrainment via morning light, chronobiotic melatonin at physiological doses (0.3-0.5mg), meal timing to synchronize peripheral clocks. This is not a sleep tracker. It is a clock-shifting tool. WHO DAWN IS FOR - Night owls who need to wake earlier for work or school (delayed sleep phase) - Jet-lagged travelers who need to recover faster (or pre-shift before flying) - New parents whose sleep has been completely disrupted - Shift workers managing rotating schedules - Anyone whose natural bedtime has drifted and needs resetting Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
