Driftless Vitals vs Vitals Flow

Driftless is a calm, private health co-pilot for busy people. It reads Apple Health, quietly learns your personal baseline, and speaks up only when something meaningfully drifts — one gentle, plain-language signal instead of another dashboard to manage. No charts to check every morning. No streaks, no scores, no pressure. Just an occasional heads-up when your body's numbers move away from what's normal for you — and silence when all is well. COMPLETELY FREE • No purchases, no subscriptions, no ads. • Every feature is unlocked for everyone. PRIVATE BY DESIGN • No account, no login, no sign-up. • No data collection of any kind — not even anonymous usage statistics. • No analytics, no trackers, no third-party SDKs. • No backend and no automatic cloud upload: processing is on-device. Health data only leaves your iPhone if you explicitly export, share, or back up. CALM, NOT ALARMIST • At most one quiet signal a day, rate-limited and debounced so you're never flooded. • Quiet hours and an adjustable frequency cap. • Warm, plain-language wording — never a red-alert dashboard. WHAT IT WATCHES Resting heart rate, heart rate variability, sleep, respiratory rate, wrist temperature, and daily activity. Driftless builds a robust personal range for each and tells you, in one sentence, when today drifts from it — plus one small suggested action. NOT A DIAGNOSIS Driftless is not a medical device. It never names a disease, never diagnoses, and never gives medical or medication advice. Every message is informational and carries a "not a diagnosis" framing. If you're concerned about your health, talk to a clinician. WORKS WITH YOUR DEVICES • Apple Watch optional — metrics like HRV, respiratory rate, and wrist temperature light up if you wear one, and the app gracefully does without if you don't. • Apple Watch app and complications for a glance at your day. • Home Screen and Lock Screen widgets. • Full support for 16 languages: English, Russian, Spanish, Portuguese, French, Italian, Czech, Turkish, Norwegian, Swedish, Finnish, Ukrainian, Simplified Chinese, Japanese, Korean, and Arabic. Driftless does one thing: it watches quietly, so you don't have to.
