Not another wearable.
The layer above all of them.
BAD fuses every wearable, lab, and health source into one unified graph — then answers the only question that matters: am I getting healthier, and what should I do this week?The moat isn't hardware. It's the intelligence on top.

The product is the intelligence
BAD computes the scores —
not the sensor.
The Apple Watch already has more sensors than most dedicated wearables. The value was never the device — it's turning raw signals into a daily decision. BAD does that one level up: from the combined graph, it derives its own scores, independent of any one device.
Recovery & Readiness
Derived from the signals BAD already fuses — HRV, sleep, resting HR, strain — not borrowed from any one device.
Training Load & Strain
Acute vs. chronic load across every workout and source, so the number reflects everything you did — not just one app.
Biological Age & Longevity
The direction we are building toward as labs, epigenetics, and body composition land. Are you aging slower than the calendar?
One Weekly Answer
"Am I getting healthier, and what should I do this week?" Grounded in your own longitudinal data — not a generic tip.
The more sources BAD fuses, the less any single wearable is load-bearing. Some scores are live today; richer ones land as more sources connect.
One graph, every source
You shouldn't care where the data came from.
Apple, Strava, Garmin, Oura, Whoop, blood labs, DEXA — it all converges into one canonical record per day and event, merged best-of-source. BAD ingests two ways: APIs and SDKs where they exist, and raw uploads(photos, screenshots, PDFs of lab reports, DEXA scans, device screens) where they don't.

Honest status: Apple Health (incl. Apple Watch) and Strava are live today. The rest are on the roadmap — each is the same shape: one adapter or upload pipeline, then it joins the graph.
How it works
One answer, from everything.
BAD reads the whole graph — every connected source — and gives you a real answer when you ask “what should I do today?”
- 1Connect Apple Health and Strava in seconds
- 2Add more sources over time — or upload labs, DEXA, and screenshots
- 3BAD fuses it all into one unified health graph
- 4Ask anything, every day. The recommendation is grounded in your own data.
What should I do today?
You've run 42 miles this week — that's 12% above your target. Today is a rest day. If you must move, 30 min easy spin at Z2. HRV is down 8%, so protect the adaptation window.
