+
+## Architecture
+
+- **Flutter** UI layer with dark monospace theme
+- **MethodChannel** (`com.traccar.client/tracking`) bridges Dart to Kotlin
+- **Foreground Service** (`LocationTrackingService`) handles location updates
+- **HeartbeatScheduler** uses `AlarmManager` (not WorkManager — callbacks lost in separate process)
+- **Offline buffering** via Room database when network unavailable
+
+## Configuration Flow
+
+1. `PermissionScreen` — guides through locationAlways + notification + battery optimization
+2. `SettingsScreen` — server URL, device ID, accuracy, intervals
+3. Preferences stored via `SharedPreferences` (synced to native via `updateConfig`)
+
+## Server Request Format
+
+```
+POST https://yourserver/?id=DEVICE_ID&lat=...&lon=...&timestamp=...&is_moving=0
+```
+
+- `is_moving` = `1` when `speed > 1.0 m/s`
+- Auth via Basic auth header if password configured
+
+## Key Patterns
+
+- **Permission flow**: WhenInUse → Always (required order for background location)
+- **Battery optimization**: `PowerManager.isIgnoringBatteryOptimizations` via BridgeModule
+- **Tracking config**: passed via `startTracking()` + `updateConfig()` (both required)
+- **Dark theme**: `Brightness.dark` with `#0d0d0d` background, teal `#00bcd4` accent

-# Traccar Client
+# TracPulse
 
-Flutter Android app for background GPS location tracking, sending data to a Traccar server.
+**Location tracking that just works.**
 
-## Build
+TracPulse runs silently in the background on your Android device, keeping your Traccar server updated with real-time location data. No complicated setup — configure your server once, and TracPulse handles the rest.
 
-```bash
-flutter build apk --debug
-```
+---
 
-The APK is output to `build/app/outputs/flutter-apk/app-debug.apk`.
+## Features
 
-## Project Structure
+- **Background tracking** — GPS updates continue even when the app is minimized
+- **Offline buffering** — Locations stored locally when offline, synced automatically when connected
+- **Configurable intervals** — Adjust how often TracPulse checks your location
+- **Heartbeat mode** — Periodic location reports keep your server alive during inactivity
+- **Battery optimized** — Designed to run efficiently without draining your battery

-  location/HeartbeatScheduler.kt  # AlarmManager heartbeat
-  network/TraccarHttpClient.kt    # POST to server
-  network/ConnectivityReceiver.kt
-```
+## Getting Started
 
-## Configuration
+1. **Install** — Grab the APK from releases and install on your Android device
+2. **Configure** — Enter your Traccar server URL and device ID
+3. **Start tracking** — Tap the toggle and TracPulse begins reporting
 
-On first launch, `PermissionScreen` guides through:
-1. **Location** — `locationWhenInUse` then `locationAlways` (background)
-2. **Notification** — required for tracking alerts
-3. **Battery** — disable Doze optimization so tracking works reliably
+---
 
-Then set server URL and device ID in Settings before starting tracking.
+## Requirements
 
-## Server Request Format
+- Android device with GPS
+- Traccar server (self-hosted or cloud)
+- Android 8.0 or higher
 
-POST to `https://yourserver/?id=DEVICE_ID&lat=...&lon=...&timestamp=...&is_moving=0`
+---
 
-- `is_moving` = `speed > 1.0 m/s` (3.6 km/h threshold)
-- Server URL and device ID come from `Preferences` (configured in Settings screen)
