wristpull
Open source · No cloud · Built in Germany

Your health data belongs at home.

wristpull pulls the data off your Garmin watch and your fitness band, keeps every heartbeat in one database in your home, and coaches you with an AI you control. No account. No subscription. No one else reading your heart rate.

No account No subscription No tracking — not even here

Why I'm building this

I'm Philipp, an IT consultant from Germany. I've spent two decades running infrastructure for companies — and the last few years watching consumer tech move the other way: everything becomes a cloud, everything becomes a subscription, and now our most private data is being fed into AI systems nobody can look inside.

Health data is the data you can't change. You can replace a leaked credit card; you can't replace your heart. Nobody knows what will be done with these records in ten years — so the safest place for them is your own home.

People who work in IT can do more than complain. We can build the alternative and prove it's better. wristpull is my attempt: local-first, open source, and soon simple enough for people who never want to touch a terminal.

Philipp — be the change.

Three reasons people switch

Keep it. See it. Use it.

You see what leaves

The AI coach reads a summary — never your life

What your devices record

  • 15,470 files, every heartbeat since 2015
  • heart rate minute by minute, day and night
  • GPS tracks of every run
  • sleep stages, stress, HRV, SpO2
  • device serial numbers

Stays on your machine. All of it.

your choice,
per run

What the coach sees

  • about 300 words of daily aggregates
  • “Resting HR 46, baseline 52”
  • “Sleep 7 h 12 min, score 81”
  • “Load ratio 0.9 — in range”
  • no raw data, no GPS, no serials

A few hundred words. Nothing more.

Don't trust it — check it. wristpull coach daily --dry-run writes the exact text to disk before anything is sent. Read what the AI would receive, then decide. No cloud service lets you do that.
