Tawen

Every readiness app hands you a number. Tawen tells you what it means. Tawen reads the sleep, heart-rate variability (HRV) and activity your phone already records through Health Connect, turns it into a daily recovery score from 0 to 100, and explains it in plain English — written by AI that runs entirely on your phone. A number with a why. And nothing leaving your device. — EXPLAINED BY ON-DEVICE AI — When your score is ready, Gemini Nano (Google's on-device AI) writes a short, plain-English note on how your day unfolded — whether your readiness climbed, dipped and recovered, held steady, or faded, and what's driving it. It runs locally on supported phones; your health data is never sent anywhere to generate it. On other phones a dependable rule-based explanation takes its place, and your score is identical. We only call it AI when AI actually wrote it. — FIVE SIGNALS, ONE HONEST NUMBER — Your readiness score is a weighted blend of five signals, calibrated to your own baseline: - Sleep (35%) — duration and sleep stages - Cardiovascular (25%) — heart-rate variability (HRV) and resting heart rate vs your baseline - Activity (25%) — movement balance, so you neither under-recover nor over-train - Body oxygen / SpO₂ (10%) — overnight blood-oxygen saturation - Thermal (5%) — skin temperature vs your baseline — HONEST WITH YOUR DATA — Tawen doesn't just average whatever it finds. Missing a signal? It scores what it has, re-weights the rest openly, and tells you the score is partial — it never invents a number to fill a gap. Conflicting step counts? It trusts your wearable, not the sum of every counter on your phone. You can always see exactly what went into your score. — NO SUBSCRIPTION. NO WEARABLE LOCK-IN. — Most recovery scores live behind a monthly membership or a band you have to keep wearing and paying for. Tawen is a private, one-time-purchase alternative to subscription wearables like Whoop and Oura — and to brand-locked scores like Garmin Body Battery — that works with the phone and wearable you already own. No $30-a-month membership. No new hardware. — PRIVATE BY ARCHITECTURE — - All scoring and AI run on your device - Only derived scores are stored — never your raw Health Connect records - Read-only: Tawen never writes back to Health Connect - Analytics and crash reporting are off by default, opt-in only, and never carry health values - No ads, no data brokering, no selling, no account - Delete everything with one tap in Settings — UPDATES THROUGH YOUR DAY — Tawen snapshots your latest data every hour, so your score keeps up — in the morning, at check-ins through the day, when you open the app, and on pull-to-refresh. — WORKS WITH WHAT YOU OWN — Any Android 9+ phone, and any wearable that writes to Health Connect — Garmin, Galaxy Watch, Pixel Watch, Fitbit, Oura, Whoop and more. Garmin users: turn on Health Connect in Garmin Connect to sync automatically (HRV needs the optional Health Sync bridge app). — ONE PURCHASE, FOREVER — Tawen is free to download. A single $4.99 purchase unlocks Pro — no subscription, ever: - 90 days of history (Free keeps 7) - The full daily insight - Weekly reports — what drove your week, in plain English Built by one independent developer. The free app is genuinely complete; Pro is simply how an indie project keeps the updates coming. — PeerPush PROMO Codes — https://play.google.com/redeem?code=RVTVBAR5X432T5KXWC8LBJF https://play.google.com/redeem?code=K6ECYUY2DEZ5GK5RU88Y25D https://play.google.com/redeem?code=3FQ21BKMHRLQBXFJRDWPJMS https://play.google.com/redeem?code=H3599BJLU6JRB0Y3ZAS6A7A https://play.google.com/redeem?code=UL1YE8ZDUSV50U5DD6UTK85 https://play.google.com/redeem?code=F1Q7S56173R1ADQD79A0578 https://play.google.com/redeem?code=XWKJB5LGRXW6LF29X35S0SL https://play.google.com/redeem?code=K4BXWVQBXBCC6DGMA6K1CC9 https://play.google.com/redeem?code=QEVUDDM19MUB6QQ02SRLT19 https://play.google.com/redeem?code=4LBMZX5VU5W9DN1HU7NJD5G https://play.google.com/redeem?code=MG
