The one place a service badge is worth reading is the car it belongs to, and that is the one place the app could not be opened: Android Auto runs no Flutter engine, so a Flutter app is simply absent from the head unit. The same APK now carries a second face — Car App Library templates the host draws itself, in Kotlin under android/app/src/main/kotlin/com/drivervault/phoneapp/car/. Two screens. The garage lists a car per row with its due badge on the second line, worst first, because the host renders only the first handful of rows and the car this list exists to mention is the overdue one rather than whichever was added first. A tap opens what that car has coming: the odometer, the next service, and the reminders the server holds for it — typed in and auto-derived from documents and the service schedule alike, in the order it sorted them. None of it is a second implementation of the app. VaultStore reads the session the phone signed in with — the active server's base and token — out of shared_preferences' own store, which both halves share, so a server switched on the phone is the server the car reads from with nothing to keep in step; only cc_active_base is new, because an untouched home entry carries no address of its own, its base being kDefaultApiBase, a compile-time define nothing outside Dart can see. CarStrings reads the same assets/i18n files by the same dot paths, so a badge on the head unit is the string format.dart already puts on the phone, in the language the account chose: of the 32 keys the car screens ask for, 28 are keys a phone screen already used, and only carApp.* is theirs. CarFormat is format.dart's twin — same date pattern and number grouping from the account's settings, same worst-of-date-and-km service badge. A new test reads the Kotlin for the keys it looks up and fails if any is missing from a language file, since the analyzer's reach stops at the Dart. It only reads. A screen you cannot type into is a poor place to edit a car and a driver is a poor person to ask, so VaultApi has no write in it to reach for by accident. Three things the README now says out loud. The service is declared IOT, the closest category the library defines for something that is a garage rather than a map or a media player, which matters to a store submission and not to a sideload. The app lock does not reach the head unit: the flag is in memory and the credentials behind it in encrypted storage, neither readable from the car service, and there is no fingerprint reader in a dashboard to satisfy it with. And the home charger is not on there — the chargers endpoint relays its plugin's payload verbatim with no shape to read, and the serial the control card is driven by is never persisted, so the car would have nothing to name.

DriverVault
A car control & service-tracking system (originally "Car Control Project").
Built incrementally — starting with a car maintenance tracker (modeled on
Car Service.xlsx) and growing toward live integration with the car via a
cellular ESP32 device and third-party services (Toyota Connected, EV chargers).
Architecture
All clients communicate with the database only through the API Server — nothing talks to PocketBase directly.

The Web and Phone apps are at feature parity.
Features
- Maintenance tracking — cars, service history (date/odometer + which parts were changed), and a per-car parts catalog, with next-due date/km status from the spreadsheet formulas.
- Technical checks — the mandatory roadworthiness inspections (przegląd techniczny / MOT / TÜV): result, cost, station and the certificate's valid-until, which overrides the car's interval and drives the next-due date.
- Maintenance log — workshop visits and repairs outside the routine schedule: type/status, workshop, parts used, labour + parts cost, invoice, warranty-until.
- Fuel tracking — refills with derived efficiency (average / best / worst consumption, cost per km, price per litre). Consumption is measured between full tanks, so partial fills roll into the next full one.
- Documents — insurance, registration, road tax and the rest, each with a server-computed renewal/expiry state.
- Reminders — date- and/or odometer-triggered, one-off or recurring, plus read-only reminders the server derives from documents and service records.
- Attachments — one optional file (PDF or image) per service record, technical check, maintenance entry, refill, document and part; fetched back through the API Server, never a public URL.
- Accounts — PocketBase-token login, profile + appearance preferences (theme/locale/date format/currency/font), avatar, email verification, data export/import, and an account-deletion state machine.
- Organizations & roles — multi-tenant
user/admin/superadminroles; admins manage users within their own organization, superadmins span all. Any user without an organization can create one and becomes its admin. - Per-user ownership & sharing — each car has an owner and can be shared with other users as read or write; the UI mirrors the server's access checks.
- Integrations — per-user connectors under a superadmin → org-admin → user cascade. Built-in today: Toyota Connected (read-only vehicle data) and the Anker Solix V1 EV charger.
- Cars from the manufacturer's own service — import a car straight off a connected account (MyToyota today), choosing what to pull in, and read everything that service knows about it from a dedicated first tab on the car. Generic over providers: the next manufacturer is one adapter in the API Server.
- EV charging control — for Anker Solix chargers the API Server runs an OCPP 1.6J Central System; in own/proxy mode the charger dials back in and the owner can start/stop and set limits from the Charging screen.
- Translated UI — the interface reads its text from per-language files (English, Polish, Danish today), with English as the fallback for any untranslated string. See TRANSLATIONS.md.
- Phone biometric login & app lock — fingerprint / face sign-in with an app-lock that requires an unlock on relaunch. See the Phone App README.
Auth model
All apps share one auth model: authentication is PocketBase's own.
POST /api/auth/login is proxied to the PocketBase users collection and the
client keeps the token PocketBase minted — the API Server does not issue its
own JWT. Every protected request carries Authorization: <token> (both
Bearer <token> and a raw token are accepted) and the server re-resolves it
against PocketBase on each call, so a role change or a deletion takes effect
immediately. Tokens are stateless, so there is no per-device session list;
changing an account's password rotates its token key and invalidates every token
already issued. Access to cars/records is gated by per-user ownership and shares;
user management requires the admin or superadmin role. Creating an organization
is the one management action open to a plain user — it promotes them to admin of
the organization they just created.
Domain (from Car Service.xlsx)
- Cars — one per vehicle (was: one spreadsheet sheet), with spec fields (engine / transmission / differential oil, brake fluid, coolant, VIN, fuel type, build / first-registration dates, …) and configurable service intervals.
- Service records — date + odometer per service, plus which parts were changed (oil & oil filter, engine air filter, cabin air filter).
- Parts — per-car catalog of part numbers.
Key spreadsheet formulas, reproduced by the API Server on read:
Next Service Date = service date + serviceIntervalDays (default 365; Excel: =A+365)
Next Service Km = service km + serviceIntervalKm (default 15 000; Excel: =B+15000)
Intervals are configurable per car.
Getting started
Bring up the stack in this order — each app's README has the details:
- API Server — configure
.env, runsetup-pocketbase.mjs, start the server. This must be running for either app. - Web App —
npm install && npm run dev(proxies/apito the server). - Phone App —
flutter build apk/flutter runwith--dart-define=API_BASE=http://<server-ip>:8080/api.
Or skip all of that and bring the whole stack up with Docker, which runs the schema setup itself — see Docker (PocketBase + API Server + Web App as three containers) or Docker-AIO (all three in a single image).
