How It Works
Your health data, finally working together.
Five steps. From your wearable to a real professional — with AI intelligence in between.
Connect your devices
Apple Watch. Garmin. Oura. Whoop.
Connect Apple Watch or Garmin directly. Oura Ring and Whoop connect via Apple Health. Setup takes under two minutes — and Fueld keeps everything in sync automatically from that point on.
- Apple Watch — native Apple Health sync
- Garmin — direct API connection (approved)
- Oura Ring — via Apple Health sync
- Whoop — via Apple Health sync
AI Health Chat
Ask your data anything — securely.
Fueld structures your health record, strips all personally identifiable information, and passes a clean data slice to a frontier AI model — so you get a deeply contextual answer that no general chatbot could produce.
- Your name, email, and identity are never sent to the AI model
- Questions use structured, anonymised data — not raw exports
- You see the exact data slice being used before it's sent
- Answers are contextual to your history — not generic
AI Health Chat is available as a premium upgrade — coming soon.
Why has my sleep been so bad this week?
Looking at your last 7 days: your sleep efficiency dropped from 87% to 79%, and your wrist temperature is running 0.3°C above your recent baseline. Combined with where you are in your cycle (day 23), this is a well-documented pattern — progesterone elevates body temperature and disrupts sleep architecture in the late luteal phase. This is likely hormonal, not habitual.
