Your body,
decoded daily.
Doppel connects to the wearables, scales, and labs you already use — WHOOP, Oura, Apple Health, Fitbit, Google Fit, Withings, DEXA, bloodwork — and turns the noise into one daily prescription.
Strain
Recovery
Sleep

From the founder
I'm building Doppel because the longevity stack I wanted didn't exist. Every metric on this page comes from my own data — I run it on myself every day. If it isn't useful at 5:30am tomorrow, it doesn't ship.
