Fuse is a fitness intelligence system for anyone working toward a health or fitness goal. It fuses your subjective inputs — how you slept, how you feel, what you ate — with the biometrics from your wearables into a single readiness score, then tells you exactly what to do today, with peer-reviewed research behind every recommendation.
Each layer of your life gets its own readiness lens. Sleep quality, body health, training output — Fuse measures each, then rolls them all into the single number above that tells you how ready you actually are right now.
You're not a dashboard. Fuse keeps you — your body, your context, your goals — at the center of every decision. Every recommendation it makes is backed by a peer-reviewed citation you can open and read. No black-box AI. No marketing claims. Just what the research actually says, applied to you.
Three layers of intelligence, one number that means something. No more staring at five apps trying to decide if you should train hard today.
Securely link Oura, Whoop, Garmin, Strava, Hevy, MyFitnessPal, and Apple/Google Health via OAuth. Your data flows in continuously — no manual entry.
Fuse merges sleep, HRV, recovery, training load, mood, and nutrition into a single 0–100 readiness score that updates throughout the day as new data arrives.
Your AI coach turns the score into clear actions — intensity, hydration, sleep windows, recovery work — each backed by a peer-reviewed citation you can verify.
Fuse reads from the wearables and apps you already use. Read-only by default; you control which sources feed the score and can disconnect any of them with one tap.
Fuse only reads the data you authorize. We never sell your information, never share it with advertisers, and never use it to train third-party AI models. Full details in our Privacy Policy and Terms of Service.
All wearable tokens encrypted with Fernet (AES-128 + HMAC). All traffic over TLS 1.2+. Database backups encrypted with the same keys.
One tap removes a device, revokes the OAuth token at the provider, and stops new data ingestion. You can also delete your account in Settings — full data export available on request.
Fuse is a paid product. We never have, and never will, sell your health data to advertisers, brokers, or any third party. The only people who see your data are you and (if you opt in) a coach you explicitly grant access to.
