Lower your baseline cortisol. CalmTide reads the Apple Health data you already have โ€” sleep, HRV, workouts, resting heart rate, mindful minutes โ€” 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 โ€ข HPA Balance Score (0โ€“100) from a named, citation-backed model โ€” tap any number to see the research behind it โ€ข One smart recommendation, chosen for today โ€” not a generic list โ€ข A daily protocol checklist: breathwork, Zone 2, sleep, morning light โ€ข Recovery signals at a glance: HRV, resting heart rate, sleep, respiratory rate โ€ข Where your HRV and resting heart rate sit against typical ranges for your age and sex (Pro) FIND YOUR PATTERNS โ€ข Morning-after insights: what caffeine, alcohol, late meals and hard workouts did to your HRV, sleep and readiness โ€” read the next morning, when the biology actually lands โ€ข What your check-ins reveal (Pro): whether how you feel actually tracks your sleep, HRV and training, compared across your own days โ€ข Your strongest cortisol link, from your own data โ€” suggestive, not causal, and always explained โ€ข Personal records: longest streak, best HPA week, calmest morning UNDERSTAND YOUR WEEK โ€ข A weekly retrospective that ranks exactly what moved your score โ€” sleep, morning light, HRV, mindfulness, training load โ€” in points, this week versus last โ€ข Every workout with heart-rate data scored for its cortisol effect: reducing, neutral, or spiking. Sessions without it still count toward your weekly dose โ€” they are never guessed at โ€ข Training load as plain figures: acute-to-chronic ratio, monotony and strain (Pro) ACT ON IT โ€ข Practice hub: cyclic sighing (Balban 2023) and resonance breathing (Steffen 2020), in 2, 5 or 10-minute doses, suggested by situation โ€” evening wind-down, post-workout, elevated load โ€ข Completed sessions save to Apple Health as Mindful Minutes โ€ข Morning-light coaching to anchor your body clock โ€” the clock that times your morning cortisol rise โ€ข Smart, quiet notifications that arrive when they help โ€” never to interrupt WATCH YOUR BASELINE FALL โ€ข An 8-week estimated baseline-cortisol trend with your life events pinned to it โ€” illness, travel, deadlines โ€” so shifts make sense โ€ข A 7-day cortisol forecast from your training and sleep (Pro) โ€ข Check in from your wrist with the Apple Watch app PRIVATE BY DESIGN โ€ข On-device analysis, including the optional Calm Coach explainer โ€ข Export or restore your data any time โ€” it's yours โ€ข App Privacy label: Data Not Collected CalmTide is free to use daily. CalmTide Pro (full 8-week trend, extended 60- and 90-day history, the cortisol forecast, score & forecast widgets, scores on Apple Watch, advanced training-load analytics and Calm Coach) is available as a monthly or annual subscription, or a one-time lifetime purchase. New subscribers get a 1-month free trial. Subscriptions auto-renew until cancelled; the price and any trial are shown before you confirm. CalmTide is a wellness tool. It estimates โ€” it does not measure cortisol, and it does not diagnose or treat any medical condition.
