CalmTide vs CALMA

CalmTide estimates stress load from your Apple Health data — it does not measure cortisol. See your stress load clearly, and settle it. CalmTide reads the Apple Health data you already have — sleep, HRV, workouts, resting heart rate, mindful minutes — and turns it into one clear picture: an HPA Balance Score today, a weekly balance trend, and a Breathe tab for when you want to settle. SEE TODAY CLEARLY • HPA Balance Score (0–100) from a named model with its sources cited — tap any number to see the research behind it • Today's estimate says how much data backs it, and a signal CalmTide couldn't measure reads "Not measured" — never as a bad day • Pick a focus — less stress, better sleep, avoiding burnout or training without overtraining — and Today and Insights lead with it • Your HRV and resting heart rate against typical ranges for your age and sex, once you confirm your age (Pro) BREATHE • A Breathe tab: cyclic sighing (Balban 2023) and resonance breathing (Shaffer 2020), in 2, 5 or 10-minute sessions, suggested for the moment you're in — free • Follow a session with your eyes closed: a gentle tap at each breath, the screen kept awake for the session only, and a pacer bar instead of the orb when Reduce Motion is on • Your mindful minutes this week from Apple Health, with no target and no streak to keep • More practices (Pro): NSDR / yoga nidra, a short cold finish for the morning, and a post-meal walk — each guided, each naming the study behind it • Sessions save to Apple Health as Mindful Minutes and count down on your Lock Screen FIND YOUR PATTERNS • Morning-after insights: what caffeine, alcohol, late meals and hard workouts did to your HRV, sleep and readiness • A one-time note when CalmTide first spots a pattern in your own check-ins — an association, never a cause • What your check-ins reveal (Pro): whether how you feel tracks your sleep, HRV and training UNDERSTAND YOUR WEEK • A weekly retrospective that ranks what moved your balance — only signals measured in both weeks (Pro) • Workouts with heart-rate data labelled reducing, neutral or spiking for their estimated load. Sessions without it still count toward your weekly dose, never guessed at • Training load as plain figures: acute-to-chronic ratio, monotony and strain (Pro) • Your weekly HPA balance over 8 weeks, with life events pinned to it, and a 7-day forecast of your load estimate (Pro) • An appointment summary: one page and a CSV of what CalmTide measured, and nothing it couldn't (Pro) ON YOUR WATCH FACE • Two complications: CalmTide balance and CalmTide readiness, each showing when it last updated (scores with Pro) • Haptic-paced breathing with your live heart rate, and check-ins that sync to your iPhone • Double Tap starts and finishes a breathing session on Apple Watch Series 9 and later • Ask Siri "What's my cortisol today in CalmTide?" for today's estimated load (Pro), or start a session from Control Center or the Action button PRIVATE BY DESIGN • On-device analysis, including the optional Calm Coach explainer • App Privacy label: Data Not Collected • On iPhone Duo, Breathe and Insights use both pages when open, and sessions adapt to every pose Scores need an Apple Watch, or another app that writes sleep, HRV or resting heart rate to Apple Health.

Most people feel tired, wired, or overwhelmed — without knowing why. CALMA changes that. It tracks your cortisol rhythm across the day, finds your personal stress patterns, and builds a guided path to help you actually fix them. This isn’t generic wellness advice. It’s your data, your patterns, your plan. — HOW IT WORKS Log a spike when something drains you. Log a restore when something helps. CALMA connects the dots — ranking what drains you most, what actually restores you, and when your system gets hit hardest. Two check-ins a day (morning and evening) take 30 seconds each. The rest happens automatically as your pattern builds. After 7 days, CALMA knows your rhythm. After 14 days, it reveals your cortisol archetype — and builds your personal Path protocol around your specific goal. — WHAT YOU’LL DISCOVER • Your #1 drainer — not just “work stress,” but exactly which category accounts for what percentage of your load • What actually restores you — ranked by your own follow-up data, not generic advice • When it happens — a heatmap showing your most vulnerable windows by time of day • Your cortisol archetype — one of four behavioral profiles with a personalized protocol built around it • Your rhythm score — a daily 0–100 number showing how balanced your stress and recovery are — YOUR PERSONAL PATH Tell CALMA what you want to change — better sleep, less reactivity, understanding your stress belly, breaking caffeine dependency — and it builds a specific, guided protocol around your goal and your real logged data. Not what works for everyone. What works for you. — FREE FEATURES • Morning and evening check-ins • Unlimited spike and restore logging • 7-day rhythm score and heatmap • Cortisol archetype (unlocks at Day 14) • Daily education and challenge cards • Your personal Path protocol CALMA PRO • 30 and 90-day rhythm trends • Restorer effectiveness star ratings • Spike → restore pairing analysis • Full weekly insight on your Rhythm Map • Shareable Weekly Rhythm Map card Pro starts at $3.99/month, $34.99/year, or $69.99 lifetime. — CALMA is not a medical device and does not diagnose or treat any condition.
