Fyzen: Recovery & Readiness
All your wearables, one score
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Apple Watch by day, GPS watch for training, ring or band at night? Every ecosystem locks your data away. Fyzen brings it together.
ONE SOURCE OF TRUTH
Fyzen aggregates Apple Health, WHOOP, Oura, Polar, Fitbit and Withings, deduplicates doubles (two watches, same workout) and reconciles conflicts — always showing you which source provided what, and why.
YOUR MORNING DECISION
A recovery score computed on YOUR baselines (never population norms), training load (TRIMP, acute:chronic ratio), sleep debt, suggested bedtime. And every morning, one clear sentence: push, maintain, or back off.
YOUR DATA IS YOURS
• 100% on-iPhone: no server, no data collected.
• Full JSON/CSV export, free, subscription or not.
• Encrypted backups (AES-GCM) restorable on a new iPhone.
• Sync across your devices through YOUR private iCloud only.
AND MORE
• Health monitor: today's vitals vs your personal ranges.
• Journal: measure the real impact of alcohol, stress, sauna… on your recovery (with honest sample sizes).
• Live sessions with a Bluetooth chest strap (Polar H10, Garmin HRM…).
• Widgets, Siri, PDF reports for your coach.
Fyzen is a wellness tool, not a medical device.
Free: Apple Health + 60 days of history. Fyzen Pro ($5.99/month, $44.99/year with a 7-day trial, or $129.99 lifetime) unlocks connectors, unlimited history, the morning decision, correlations and reports.
