InnerRipple: Know Your Health
Insights that fuel better days
Free
AI-generated insights from your trailing 30 days. HRV Training Mode on Apple Watch. Ambient sounds in Mindful Minute. Every recommendation cites peer-reviewed research.
We read your heart, sleep, breath, motion, and body signals, interpret them against your own trailing 30-day baseline, and cite the peer-reviewed research under every threshold. Not just what's happening, but why it matters and what the studies actually say.
YOUR BASELINE, NOT EVERYONE ELSE'S
A 50 ms HRV reading isn't good or bad in a vacuum. It's good for you if your baseline is 40 ms, and worth attention if your baseline is 70 ms. In the first two weeks, while we learn your patterns, baseline-dependent rows say "BASELINE PENDING."
THE RESEARCH UNDER EVERY NUMBER
Every threshold cites a peer-reviewed source or official clinical guideline: JAMA, Lancet, AHA, BMJ, Sleep, ADA Standards of Care, ACC/AHA Hypertension Guideline. When InnerRipple says 6 hours is below optimum, you see the meta-analysis (Yin et al., JAHA 2017) and the dose-response curve. Citations are tappable and open the source in-app. No vibes, no slogans.
WHAT YOU'LL SEE
• Composite score: motivation, not diagnosis
• Tonight's Action: the single most impactful adjustment for tonight, cited
• Signal Status: 50+ diagnostic rows across Cardiovascular, Body, Activity, and Mental & Behavior
• Sleep: 6 independent dimensions (duration, regularity SRI, deep sleep, awakenings + WASO, nighttime HR dip, apnea screening on Apple Watch Series 9+)
• Fitness Age: a heuristic from VO₂ max, HRV, and resting HR - labeled as a heuristic, not a clinical measurement
• Trends: 180 days of daily history with per-metric contributor breakdown
• Insights: peer-reviewed cause-effect patterns surfaced from your data, generated on-device by Apple Intelligence
ON YOUR WRIST
InnerRipple includes a watchOS companion with five surfaces: Today's composite score, Today's Ripple (contribution toward your healthspan), Sleep Recap (auto-shown on wrist raise after wake), Mindful Minute with three breath patterns and five ambient sounds, and HRV Training Mode (a 5 or 10 minute resonance breathing session with live heart rate and baseline comparison). Three watch face complications and a Smart Stack widget. Reads HealthKit independently. Works without the iPhone nearby.
HONEST ABOUT WHAT WE CAN'T SEE
InnerRipple reads heart, sleep, breath, movement, body composition, and temperature signals as part of initial launch (we are actively working on expanding these). Some health factors live outside that
scope: smoking, alcohol, diet quality, medications, genetics, pre-existing conditions, environmental exposures. Some can be logged manually in Apple Health, but InnerRipple's scoring doesn't include them. A high score doesn't mean you're healthy if those factors are unfavorable. We tell you this in the disclaimer, not after you've already drawn conclusions.
ZERO SERVERS, ZERO ANALYTICS
No accounts. No logins. No tracking. No third-party SDKs. Everything is computed on your iPhone's processor. Apple Health permissions are managed in iPhone Settings, so you can revoke any signal anytime.
Free.
NOT A MEDICAL DEVICE
InnerRipple is an educational tool, not a medical device. It does not diagnose, treat, cure, or replace clinical care. Always consult a qualified healthcare provider for medical concerns. The full disclaimer shows on first launch and is reviewable in Settings.

Ratings & Reviews
v1.0.1 - Cross-metric insights, HRV training with lab-grade math, iPad, and the Tonight's Action loop.
NEW: FOUNDATION MODELS INSIGHTS (IPHONE)
On-device pattern detection across your trailing 30 days. Sleep
regularity, HRV trends, recovery patterns, plus cross-metric
correlations like "Your HRV drops 12% the morning after sleep
below 6h." Every card cites a peer-reviewed study. Powered by
Apple Intelligence on supported devices. Nothing leaves your phone.
NEW: HRV TRAINING (WATCH + IPHONE)
A 5 or 10 minute resonance breathing session with live heart rate
on the watch. Session HRV is now computed from actual beat-to-beat
intervals (Series 4+), methodologically equivalent to Apple's
24-hour SDNN baseline. Trends tab on iPhone tracks your sessions
over time with a best-session marker. Lehrer and Gevirtz 2014
protocol. Saves to Apple Health as a Mind and Body workout.
NEW: TONIGHT'S ACTION LOOP (IPHONE + WATCH)
The daily recommendation card stands out, with a Mark Done button
on both iPhone and watch. Trends shows "5 of last 7 days
completed." Mark Done flows both ways across devices.
NEW: MINDFUL MINUTE, EXPANDED (IPHONE + WATCH)
Three breath patterns: Box (4-4-4-4) for focus, Resonance (6-6)
for HRV, Calm (4-7-8) for pre-sleep wind-down. Five ambient
sounds: White Noise, Ocean, Rain, River, Forest. Settings sync
across devices.
NEW: SLEEP EFFICIENCY + CHRONOTYPE (IPHONE)
Two new Signal Status rows. Efficiency is time asleep over time
in bed (Buysse 1989 PSQI: 85% or more is healthy). Chronotype is
morning, intermediate, or evening, derived from your 30-day sleep
midpoint (Roenneberg 2003 MCTQ).
NEW: CAFFEINE AWARENESS (IPHONE)
Reads dietary caffeine from Apple Health. Use ProdDuck or any
drink-logging app? Your logged drinks show up here. Pattern
detection ties caffeine to next-night sleep efficiency
(Drake 2013, J Clinical Sleep Medicine).
NEW: IPAD LAYOUT
A native iPad experience with a sidebar for tab and Today layout
switching. 2-column Insights grid. Portrait and landscape both
supported.
NEW: SMART-TIMED NOTIFICATIONS + DAYLIGHT COMPLICATION
Evening reminder fires at the hour that matches your
recommendation: sleep wind-down at 9pm, mindfulness at 8pm, walks
90 minutes before local sunset (location-aware, opt-in). You can
customize each notification time in Settings. A new sunset-
countdown complication brings daylight tracking to your watch face
(Series 4 and later).
NEW: TRENDS TIME-WINDOW FILTER
Filter the ledger by 7, 30, 90, or 180 days from the top of
Trends.
NEW: SIRI SHORTCUTS
"Hey Siri, log a mindful minute." "Hey Siri, start HRV training."
FIXES
* Sleep regularity math: circular statistics fix prevents the rare
500+ minute display caused by a midnight-wrap bug.
* Mindful Minute on watch no longer writes duplicate entries on
session completion.
* HealthKit permission prompts are cached; no more re-asks every
launch. Settings has a "Re-request health access" button for
users who tapped Don't Allow initially.
* HRV training sessions under 30 seconds are discarded instead of
cluttering history.
* Three citation URLs corrected to point to the right peer-reviewed
papers.
* Mindful session completion haptic fires even when wrist is down.
* Watch composite score reliably matches iPhone on first launch.
* Today's Ripple widget no longer truncates on older Apple Watches.
Same brand: every threshold cites a peer-reviewed source, every
score is computed from YOUR baseline, nothing leaves your phone.
