## What it is
-HealthLog is a self-hosted personal health tracker that runs from a single `docker compose up`. It covers the metrics most people actually log -- weight, blood pressure, pulse, body composition, blood glucose, sleep, mood, and medication compliance -- and brings them together in one dashboard with reference ranges from ESH 2023, ADA 2024, and NICE NG115. Withings and WHOOP devices sync automatically over OAuth2; an `export.zip` import folds your full Apple Health history into the same timeline; a native SwiftUI iOS client (public-beta via [TestFlight](https://testflight.apple.com/join/bucuTBpa)) streams HealthKit live; multi-provider AI Insights (BYOK or local) explain what the numbers mean; a doctor-report PDF generates client-side. EN/DE end-to-end. AGPL-3.0.

Behaviour, API shapes, and database schema can change between minor versions; migrations are forward-only and not all are rehearsed against every legacy fixture. If you self-host, pin a tag, take a backup before every upgrade, and read the [CHANGELOG](CHANGELOG.md) before pulling `latest`. Issue reports and PRs welcome — this is the rough edge where the project gets sharper.

The wrist-band ecosystems are good at what their hardware measures, and HealthLog does not try to be a ring or a strap. It does not ship a sensor, and it does not claim to match one. What it does is take the readings those devices already collect — plus the ones they don't hold, like cuff blood pressure, finger-stick or CGM glucose, and medication intake — and keep them on a server you run.

+**Mood Logging** -- A five-face mood capture (a 1–5 scale) backed by a structured tag catalog and rated daily-life factors. Pick binary tags from categories covering feelings, sleep, health (including nutrition tags like ate-well, fast-food, no-sweets, big-meal), social, work, and hobbies; score rated factors — work, social, sleep quality, stress, and conflict — on their own scale (1–5, or yes/no for conflict), with stress and conflict flagged as inverse so a higher score reads as a worse day. Add a free-text note, then read it back through trend analytics and a mood-relations surface that associates your tags and factors with your other metrics. The standalone moodLog.app webhook is deprecated now that mood is tracked fully inside HealthLog; it stays functional for existing integrations.
**Medication Compliance** -- Flexible scheduling driven by a single recurrence engine: time windows, day-of-week recurrence, `intervalWeeks`, rolling intervals, RFC-5545 RRULE, one-time doses, as-needed (PRN), and cyclic on/off-week plans — so once-weekly GLP-1 injections, weekday-only doses, and non-daily plans score honestly against their real cadence rather than a daily denominator, everywhere from the dashboard tile to the detail page. Route of administration (oral / injection / other) carries the injection-site picker for any injection. Take / skip / snooze logging, compliance heatmaps, GLP-1 pen-inventory + injection-site rotation, structured side-effect tracking. External API for iOS Shortcuts integration.
**Withings Integration** -- OAuth2 device sync for scales, blood pressure monitors, and activity trackers with automatic deduplication.
+**WHOOP Integration** -- Connect a WHOOP account with your own WHOOP developer OAuth client (client id/secret pasted into Settings, stored encrypted). Recovery, strain, sleep, body, and workout data sync server-side over OAuth2, with a connection test, manual sync (incremental or full history), and a resume control to recover from a revoked grant.

+**Google Health / Fitbit Integration** _(experimental)_ -- Connect Fitbit and Pixel data through Google's Health API on your own Google Cloud OAuth client (client id/secret in Settings, encrypted at rest). Activity (steps, distance, active energy, floors, VO₂ max), health metrics (weight, body fat, SpO₂, resting heart rate, HRV, respiratory rate, wrist temperature, spot heart rate), per-stage sleep, and exercise workouts import server-side with the same connection-test / sync / resume controls as WHOOP. Because the Google Health API is young and several per-type value fields are not yet fully published, this connection is **experimental** — some data types may import nothing until the wire mapping is verified against a live account, and each operator's OAuth client needs Google brand verification plus an annual CASA assessment before it can leave Testing mode.

**Apple Health import** -- Drop your iOS `export.zip` on the import page. A streaming parser handles multi-gigabyte archives (Zip64), folds every ``, ``, ``, and `` into the same timeline as your other metrics, and stays idempotent on re-upload. Per-type ingestion stats plus a live status endpoint so you can watch the progress on a long historical drain.

+### Source priority
+
+When two providers report the same metric — a Withings scale and an Apple Watch both logging weight, or HealthKit and Fitbit both reporting steps — HealthLog keeps every row as an audit trail but applies a per-metric source priority to decide which reading is canonical. Cumulative metrics (steps, distance, active energy, floors) pick exactly one source per day so they are never double-counted; point measurements (weight, blood pressure, HRV) pick a display-preferred source. The default ladder reflects measurement reliability for each metric class: a dedicated scale outranks a wrist estimate for weight, a recovery strap leads the sleep and HRV ladders, and a cuff leads blood pressure. The ladder is per-user adjustable, and an optional device-type tie-break decides between two devices on the same source. The underlying idea is [data fusion](https://en.wikipedia.org/wiki/Data_fusion) — combining several imperfect sensors into a single, more reliable estimate rather than averaging them blindly.
