+# OpenClimb for Android
+
+This is the native Android app for OpenClimb, built with Kotlin and Jetpack Compose.
+
+## Project Structure
+
+This is a standard Android Gradle project. The main code lives in `app/src/main/java/com/atridad/openclimb/`.
+
+-   `data/`: Handles all the app's data.
+    -   `database/`: Room database setup (DAOs, entities).
+    -   `model/`: Core data models (`Problem`, `Gym`, `ClimbSession`).
+    -   `repository/`: Manages the data, providing a clean API for the rest of the app.
+    -   `sync/`: Handles talking to the sync server.
+-   `ui/`: All the Jetpack Compose UI code.
+    -   `screens/`: The main screens of the app.
+    -   `components/`: Reusable UI bits used across screens.
+    -   `viewmodel/`: `ClimbViewModel` for managing UI state.
+-   `navigation/`: Navigation graph and routes using Jetpack Navigation.
+-   `service/`: Background service for tracking climbing sessions.
+-   `utils/`: Helpers for things like date formatting and image handling.
+
+The app is built to be offline-first. All data is stored locally on your device and works without an internet connection.

+# OpenClimb for iOS
+
+The native iOS, watchOS, and widget client for OpenClimb, built with Swift and SwiftUI.
+
+## Project Structure
+
+This is a standard Xcode project. The main app code is in the `OpenClimb/` directory.
+
+-   `Models/`: Swift `Codable` models (`Problem`, `Gym`, `ClimbSession`) that match the Android app.
+-   `ViewModels/`: App state and logic. `ClimbingDataManager` is the core here, handling data with SwiftData.
+-   `Views/`: All the SwiftUI views.
+    -   `AddEdit/`: Views for adding/editing gyms, problems, etc.
+    -   `Detail/`: Detail views for items.
+-   `Services/`: Handles HealthKit and sync server communication.
+-   `Utils/`: Helper functions and utilities.
+
+## Other Targets
+
+-   `OpenClimbWatch/`: The watchOS app for tracking sessions.
+-   `ClimbingActivityWidget/`: A home screen widget.
+-   `SessionStatusLive/`: A Live Activity for the lock screen.
+
+The app is built to be offline-first. All data is stored locally on your device and works without an internet connection.

+# Sync Server
+
+A simple Go server for self-hosting your OpenClimb sync data.
+
+## How It Works
+
+This server is dead simple. It uses a single `openclimb.json` file for your data and a directory for images. The last client to upload wins, overwriting the old data. Authentication is just a static bearer token.
+
+## Getting Started
+
+1.  Create a `.env` file in this directory:
+    ```
+    IMAGE=git.atri.dad/atridad/openclimb-sync:latest
+    APP_PORT=8080
+    AUTH_TOKEN=your-super-secret-token
+    DATA_FILE=/data/openclimb.json
+    IMAGES_DIR=/data/images
+    ROOT_DIR=./openclimb-data
+    ```
+    Set `AUTH_TOKEN` to a long, random string. `ROOT_DIR` is where the server will store its data on your machine.
+
+2.  Run with Docker:
+    ```bash
+    docker-compose up -d
+    ```
+    The server will be running on `http://localhost:8080`.
+
+## API
+
+The API is minimal, just enough for the app to work. All endpoints require an `Authorization: Bearer <your-auth-token>` header.
+
+-   `GET /sync`: Download `openclimb.json`.
+-   `POST /sync`: Upload `openclimb.json`.
+-   `GET /images/{imageName}`: Download an image.
+-   `POST /images/{imageName}`: Upload an image.
+
+Check out `main.go` for the full details.
