Lower your baseline cortisol. CalmTide reads the Apple Health data you already have — sleep, HRV, workouts, resting heart rate, mindful minutes — and turns it into one clear picture of your stress biology: an HPA Balance Score today, and an estimated baseline-cortisol trend over 8 weeks. Not another meditation timer. A measurement layer for calm. Everything runs on your device. No account, no cloud, no analytics. Your health data never leaves your phone. SEE TODAY CLEARLY • HPA Balance Score (0–100) from a named, citation-backed model — tap any number to see the research behind it • One smart recommendation, chosen for today — not a generic list • A daily protocol checklist: breathwork, Zone 2, sleep, morning light • Recovery signals at a glance: HRV, resting heart rate, sleep, respiratory rate • Where your HRV and resting heart rate sit against typical ranges for your age and sex (Pro) FIND YOUR PATTERNS • Morning-after insights: what caffeine, alcohol, late meals and hard workouts did to your HRV, sleep and readiness — read the next morning, when the biology actually lands • What your check-ins reveal (Pro): whether how you feel actually tracks your sleep, HRV and training, compared across your own days • Your strongest cortisol link, from your own data — suggestive, not causal, and always explained • Personal records: longest streak, best HPA week, calmest morning UNDERSTAND YOUR WEEK • A weekly retrospective that ranks exactly what moved your score — sleep, morning light, HRV, mindfulness, training load — in points, this week versus last • Every workout with heart-rate data scored for its cortisol effect: reducing, neutral, or spiking. Sessions without it still count toward your weekly dose — they are never guessed at • Training load as plain figures: acute-to-chronic ratio, monotony and strain (Pro) ACT ON IT • Practice hub: cyclic sighing (Balban 2023) and resonance breathing (Steffen 2020), in 2, 5 or 10-minute doses, suggested by situation — evening wind-down, post-workout, elevated load • Completed sessions save to Apple Health as Mindful Minutes • Morning-light coaching to anchor your body clock — the clock that times your morning cortisol rise • Smart, quiet notifications that arrive when they help — never to interrupt WATCH YOUR BASELINE FALL • An 8-week estimated baseline-cortisol trend with your life events pinned to it — illness, travel, deadlines — so shifts make sense • A 7-day cortisol forecast from your training and sleep (Pro) • Check in from your wrist with the Apple Watch app PRIVATE BY DESIGN • On-device analysis, including the optional Calm Coach explainer • Export or restore your data any time — it's yours • App Privacy label: Data Not Collected CalmTide is free to use daily.
