InnerRipple is an educational tool, not a medical device. It does not diagnose, treat, or prevent any condition. Always seek the advice of your doctor in addition to using this app, and before making any medical decision. We show your own Apple Health readings against your own trailing baseline or a published reference range, and cite the source behind every comparison. HOW STEADY YOUR OWN READINGS ARE A number is only worth reading if it holds still long enough to mean something. So we measured how much each overnight reading carries from one night to the next, across months of nights, and weighted the scoring to match. On the watch we measured, overnight HRV moved largely at random, so it counts for less than resting heart rate, which holds. Heart signals are read against your own baseline: 50 ms HRV is good for you if your baseline is 40 ms. Early on, those rows say "BASELINE PENDING." THE RESEARCH UNDER EVERY NUMBER Every comparison cites its source, a peer-reviewed study or a published guideline, tappable so you can read it yourself. When InnerRipple notes that 6 hours is under the published adult range, you see where that range comes from (the AASM and Sleep Research Society put adults at 7 to 9 hours). WHAT YOU'LL SEE • Today's Investment: motivation, not diagnosis • Daily action: one cited suggestion, checked against Apple Health • Signal Status: each Apple Health reading against your own baseline or a cited reference range • Sleep: up to 8 dimensions, from duration and regularity to deep sleep and nighttime heart rate dip • Waist-to-height: your waist against your height, in NICE's guideline bands • Fitness Age: an estimate from your VO₂ max, with every step of the working one tap away • Trends: 180 days of history with per-metric contributor breakdown • Insights: patterns from your own data, written on-device by Apple Intelligence where available YOUR BLOODWORK, ON YOUR DEVICE Scan a lab report or enter values by hand, and InnerRipple trends each marker over time, even across labs. You confirm every scanned or typed value before it is used. An out-of-range marker adds plain-language context to what your wearable sees, like low ferritin alongside low HRV, described and never prescribed. Your entries sync through your own private iCloud. Never a diagnosis. ON YOUR WRIST A watchOS companion with five surfaces: Today's Investment, Today's Ripple, Sleep Recap (on wrist raise after wake), Mindful Minute with three breath patterns and five ambient sounds, and HRV Training Mode (resonance breathing with live heart rate). Three complications and a Smart Stack widget. Reads HealthKit on its own, so it works without the iPhone nearby. HONEST ABOUT WHAT WE CAN'T SEE InnerRipple reads heart, sleep, breath, movement, body measurement, and temperature signals. Other health factors live outside that scope: smoking, alcohol, diet quality, medications, genetics, pre-existing conditions, environmental exposures. InnerRipple's scoring doesn't include them, so a high score doesn't mean you're healthy if those factors are unfavorable. ZERO SERVERS, ZERO ANALYTICS No accounts. No logins. No tracking. No third-party SDKs. Everything is computed on your iPhone and Apple Watch. On a locked iPhone, widgets hide your readings and Siri asks you to unlock first. Revoke any Apple Health permission anytime in iPhone Settings. Free. NOT A MEDICAL DEVICE InnerRipple is an educational tool, not a medical device. It does not diagnose, treat, cure, or replace clinical care, and nothing in it should be used to make a medical decision on your own. Always seek the advice of your doctor.
