Code-review and design follow-ups before the v1.22 cut. No behaviour change
beyond the items below.
Coach / insights:
- Coach SSE route: a non-provider error raised inside the open producer (e.g. a
DB failure persisting the reply) now records on the wide event and forwards to
GlitchTip instead of masquerading as a provider outage; it still surfaces an
error frame since the stream is open.
- Lab ↔ outcome correlations: hedge faint-tier pairs ("a faint hint, if
anything … too small to lean on") so the narrated confidence never outruns the
effect, matching the daily engine.
- Reminder sweep: mint the plan-review reminder and clear the plan's reviewDate
in one transaction so a half-applied write can't duplicate the reminder.
- Fold the two raw provider-fallback runners onto one shared chain walker.
Design / accessibility:
- Lift sub-44px tap targets to the 44px mobile floor (suggested-action card,
Coach bubble affordances), brighten the resting timestamp clock for non-text
contrast, and route the lab chart height through the shared constant.
- Replace ad-hoc arbitrary type sizes with the scale token and static size-11
icon buttons with the named icon-lg variant.
- Settings: add the missing About card-header descriptions, normalise the
low-stock numeric widths, and relax the notification-status rows from nested
cards to a divided list.
Housekeeping:
- Drop three unused exported types (and the now-orphaned source const), re-stamp
v1.21.5 comments to v1.22, and register the live-judge eval harness as a knip
entry so the script-only module resolves.
HealthLog
Self-hosted, privacy-first health tracking. Your vitals, your devices, your server.

Why HealthLog
HealthLog is a self-hosted health tracking app (PWA + native iOS client) that runs from a single docker compose up on a NAS, homelab, or small VPS. It brings weight, blood pressure, pulse, blood glucose, body composition, sleep, mood, menstrual cycle, and medications onto one timeline — synced from the devices you already own — and keeps everything encrypted at rest on hardware you control. No vendor cloud, no subscription, no telemetry.

Highlights
- Every vital on one timeline. Weight, blood pressure, pulse, glucose, body composition, sleep, SpO₂, mood, and cycle tracking — charted with trends, moving averages, and clinical reference ranges (ESH 2023, ADA 2024), overridable with the targets your clinician set.
- Your devices, one server. Withings, WHOOP, Oura and Polar sync over OAuth2, Fitbit connects experimentally over the Fitbit Web API, an Apple Health
export.zipfolds your full history in, and the native iOS app streams HealthKit live. A per-metric source priority decides which reading is canonical when wearables overlap. - Medication tracking that tells the truth. Flexible schedules (weekly injections, weekday-only, intervals, PRN, cyclic), a configurable intake window per dose, and a traceable dose history where every slot reads taken, late, skipped, or missed — the same ledger the compliance rate is computed from, so the percentage can never disagree with the timeline.
- AI insights you own. Daily briefing, health scores, correlations, and a conversational coach grounded in your own measurements, with proactive check-ins. Bring your own OpenAI or Anthropic key, or point at a local endpoint (Ollama, LM Studio, vLLM) so nothing leaves your network.
- Clinician-ready output. A doctor-report PDF generated client-side, a read-only HL7 FHIR R4 API, and scoped, time-limited share links you revoke after the visit.
- Private by construction. AES-256-GCM encryption at rest with zero-downtime key rotation, passkey login, server-side sessions, strict CSP — and no third-party tracking anywhere.
- Built to be lived in. Installable PWA with offline support, medication reminders over APNs, Telegram, ntfy, and Web Push, a sub-second dashboard on years of imported history, English and German end to end.

Quick start (Docker Compose)
git clone https://github.com/MBombeck/HealthLog.git && cd HealthLog
cp .env.example .env
# Generate the three secrets (each a 64-char hex string = 32 bytes):
echo "POSTGRES_PASSWORD=$(openssl rand -hex 32)" >> .env
echo "ENCRYPTION_KEY=$(openssl rand -hex 32)" >> .env
echo "API_TOKEN_HMAC_KEY=$(openssl rand -hex 32)" >> .env
# LAN / plain-HTTP host (NAS, homelab, Tailscale) — required, or login fails:
echo "SESSION_COOKIE_SECURE=false" >> .env
docker compose up -d
Open http://localhost:3000 (or http://<host>:3000) — the first registered user becomes admin. The compose file pulls a pre-built multi-arch image (amd64 + arm64) from GHCR; no build step required.
Verify the running version:
curl -s http://localhost:3000/api/version # returns version + buildSha + builtAt
SESSION_COOKIE_SECURE=false is the one setting plain-HTTP self-hosts must set: without it the session cookie carries the Secure flag, the browser drops it over HTTP, and login silently fails. Leave it unset (or true) only when a TLS reverse proxy serves HTTPS — and then set NEXT_PUBLIC_APP_URL and APP_URL to the public URL first (see the self-hosting guide).
Persistent state lives in exactly one named volume (pgdata, the Postgres data dir); the app container is stateless, so backing up the database backs up everything.
NAS and homelab users have ready-made paths: Unraid Community Applications and Portainer app templates.
Self-hosting
One container hosts both the web server and the job worker by default; split them via HEALTHLOG_PROCESS_TYPE=web|worker for horizontal scale. Encrypted daily backups to any S3-compatible bucket are opt-in via the admin panel, new users join by invite link or QR code, and the stack works out of the box behind Caddy, Traefik, Nginx, or Coolify.
HealthLog ships releases roughly weekly. Pin a tag, back up before upgrades, and skim the CHANGELOG before pulling latest. The operator manual — reverse proxy, migrations, encryption-key rotation, backup and restore — lives at docs.healthlog.dev.
Native iOS app
A SwiftUI companion in public beta via TestFlight, built on the same API as the web client: live HealthKit two-way sync, medication reminders with action buttons that work without opening the app, and an on-device coach on Apple-Intelligence-capable iPhones. Code lives in MBombeck/healthlog-iOS.
Tech stack
Next.js 16 (App Router, React Server Components), TypeScript strict, PostgreSQL 16 with Prisma, pg-boss for jobs, Tailwind CSS 4 + shadcn/ui, Recharts, WebAuthn passkeys, Vitest + Playwright, multi-stage Alpine Docker image. The OpenAPI 3.1 contract for native clients is generated from the Zod schemas at docs/api/openapi.yaml.
