Founder's edition — first thousand only
Your wearable already knows.
Nothing closes the loop.
Oura, Whoop, and Apple Health measure your recovery every night. The data sits in an app you check once and act on rarely. Syne is the practice and the score that closes that loop — a clinical evening formula, and an app that turns your own data into one thing to do tonight.
One email, when it matters. Going live early 2027. No spam, no drip sequence — just the launch.
You have more recovery data than any generation before you. It still isn't doing anything.
The wearable measures. The app displays. And then the loop stops — because a score on a screen isn't a decision, and nothing tells you what to actually do with it tonight.
- 01
Measure
Oura, Whoop, or Apple Health capture HRV, sleep stages, and resting heart rate automatically, every night.
- 02Loop breaks here
Display
A readiness score appears in the morning. Interesting. Rarely actionable, and disconnected from what happens that evening.
- 03Unclosed
Nothing
No prompt, no practice, no clear next step. The same debt carries into tomorrow’s reading.
- 04
Repeat
Tomorrow’s score reflects tonight’s debt. Without an intervention, the pattern compounds in the wrong direction.
A practice and a score, built to close the loop your wearable opened.
Two parts, one system. RESTORE is the nightly practice. Bio-Sync Score is what reads your own data back to you as one decision, not a dashboard.

The score
Bio-Sync Score
Reads your wearable, tells you tonight's move
Connects to Oura, Whoop, and Apple Health and turns the data you're already collecting into a single number and a single action — closing the gap between what your wearable measured last night and what you actually do about it tonight.
HRV trending down 3 nights running. Tonight: RESTORE at your usual hour, lights down by 10:30.
Fifteen years of watching high performers measure recovery and act on none of it.
“I built Syne after fifteen years watching high-performing professionals in London, New York, and Mumbai wear a $300 recovery tracker and run themselves into a recovery debt they couldn't see. The data was never the missing piece. The missing piece was the loop back from that data to something you actually do at night. That's what we've built — formulated with chartered pharmacologists, manufactured in the United Kingdom, measured against your own data.”
