What it can do

One system, five jobs

wristpull collects your data, shows it to you, helps you understand it, turns it into training — and makes sure you keep it forever. Everything below ships today and runs every morning on real hardware.

Collect — without a vendor in the loop

Garmin watch over USB. Plug in the cable; every new file is copied, archived and parsed. Nothing on the watch is ever deleted or modified.
Fitness band over Bluetooth — no phone needed. wristpull speaks the band's own protocol and pulls activity, sleep, stress, HRV, SpO2, even workouts with GPS, straight to your machine.
Gadgetbridge supported too. Already syncing with the open-source app? wristpull pulls its export over ADB and imports years of its history on day one.
Your whole Garmin history. Request your account export from Garmin, hand wristpull the zip: ten years — roughly 15,000 files — import in about 25 minutes, including activity names, VO2max and weight history.
Plug in and forget. On the full setup, connecting the watch starts the import automatically; a guided morning routine walks through watch, band and coach in one go.

Look — today and ten years back

Dashboard on your phone. Today's recovery against your 28-day baseline, trends from four weeks to ten years, activities with heart-rate curves and laps, nights with sleep stages — served over HTTPS from your own network, password-protected.
Watch and band side by side. Two devices on one body rarely agree; wristpull shows both honestly instead of averaging the difference away.
A terminal UI for terminal people. Ten screens, keyboard-first, German and English — the same numbers as the dashboard.
Reports and exports. Weekly and monthly Markdown reports with charts, plus a compact export you can paste into any AI chat for a second opinion.

Understand — an AI coach you can audit

Morning check & weekly review. Recovery status, a suggestion for today, and on Sundays a plan for next week — built on your sleep, load and heart-rate baselines.
The model you choose. A local model on your own machine (nothing leaves the house), or a cloud model when you want sharper answers — your choice, per run.
A tiny, visible extract. The coach receives a few hundred words of daily aggregates. Never raw samples, never GPS, never serial numbers.
Dry run before trust. One flag writes the exact prompt to disk before anything is sent — read it, then decide.
No hallucinated numbers. All statistics are computed in Python first; every number in the answer is checked against the data, and anything the model invented is flagged.
It remembers and learns. Rate every answer, keep a one-line journal; the coach sees both next time and scores how well the week followed its own plan.

Train — the plan lands on your wrist

Workouts as simple text files. Warm-up, main part, cool-down, interval repeats — each step with a heart-rate target.
Pushed to the watch over the same cable. No Garmin Connect account: unplug, and the watch guides every step of the session.
From the coach's plan. One command turns the weekly plan into draft workouts; verify reads the watch back to confirm what it accepted.
Knows the watch's quirks. Warns before the watch's workout limit silently swallows files, and guards against duplicate names.

Keep — yours in ten years, too

Raw files are sacred. Everything is archived byte-identical and checksummed before it is parsed; interpretations can be redone anytime, originals never change.
One open database. Twenty documented SQLite tables — run your own SQL, point any analysis tool at it, or just copy one file to back up a decade.
Whole-state backup & move. One command packs data, config and secrets into a single archive; one command restores it on a new machine in minutes.
If wristpull disappeared tomorrow you'd still hold your FIT files and a plain SQLite database that dozens of independent tools can read. That's the design, not an accident.

Honest limits

Read this before you trust a number

Not a medical device

The coach refuses diagnoses and points you to a doctor when values look off. Treat it as a training partner with a good memory, not a clinician.

Verified on real wrists — two of them

Daily drivers are a Garmin fēnix 6X Pro and an Amazfit Helio Strap, cross-checked value by value. Other Garmin watches and Gadgetbridge-supported bands should work; some need small parser additions — that's what the issues tab is for.

Sync is a race

A Garmin watch deletes monitoring files once any app has fetched them. If the vendor app syncs first, those hours are gone for everyone else. wristpull documents the order that keeps your archive complete.
