Your wearable talks to your peptide protocol.

One dashboard. HRV next to your tesa cycle. Sleep score next to your last lab draw. Steps next to your dose calendar. Apple Health, Whoop, Garmin, and the long tail — all funnel into the same trend view and the same StackAI context.

How it works

Three taps, then it's automatic

01

Create your account, add your peptide stack and recent labs, then upgrade to Optimizer ($14.99/mo) to unlock wearable sync.

02

Drop your export

Export from Apple Health, Whoop, Garmin (or fill our template) and drop the file into Settings → Data. We parse it in your browser — your raw export never leaves your device.

03

See the connection

HRV trends sit next to your dose calendar. Sleep score lines up with cycle weeks. StackAI reads it all in context — your protocol, your labs, your wearable signal — together.

Your raw export never leaves your device

The XML / CSV is parsed entirely in your browser — we POST only the small per-day aggregate to our server. A 200MB Apple Health export becomes a ~200KB JSON. Your raw file stays on your machine.

Idempotent uploads

Re-export from your iPhone any time and re-upload — duplicate days are skipped via a (user, date, source) unique key. Use it as a weekly sync until OAuth lands.

One trend view, three sources

HRV from Apple, sleep from Whoop, RHR from Garmin — the trend chart unifies them. Source provenance is preserved per row so you can always trace back where a number came from.
