+# Simple Counter - Textual + Aptabase
+
+A minimal example demonstrating how to integrate [Aptabase](https://aptabase.com/) analytics into a [Textual](https://textual.textualize.io/) TUI application.
+
+Perfect for learning the basics of adding privacy-first analytics to your terminal apps!
+
+## 🎯 What It Does
+
+This is a simple counter app that:
+- Increments a counter when you click a button
+- Resets the counter to zero
+- Tracks all interactions with Aptabase analytics
+- Shows notifications for user feedback
+
+## 📸 Features
+
+- **Clean UI**: Centered layout with large counter display
+- **Two Buttons**: 
+  - "Click Me!" - Increments the counter
+  - "Reset" - Resets to zero
+- **Analytics Tracking**:
+  - App start/stop events
+  - Button clicks with counter values
+  - Reset actions with previous count
+  - Session duration
+
+## 🚀 Quick Start
+
+### Installation
+
+#### Using uv (recommended)
+
+```bash
+# Install dependencies
+uv pip install textual aptabase
+
+# Run the app
+uv run main.py
+```
+
+#### Using pip
+
+```bash
+# Create and activate virtual environment
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install dependencies
+pip install textual aptabase
+
+# Run the app
+python main.py
+```
+
+#### Using pyproject.toml
+
+```bash
+# If you have the pyproject.toml file
+uv sync
+uv run counter
+```
+
+## ⚙️ Configuration
+
+Before running, you need to set your Aptabase app key:
+
+1. Sign up at [aptabase.com](https://aptabase.com/)
+2. Create a new app
+3. Copy your app key (format: `A-EU-XXXXXXXXXX` or `A-US-XXXXXXXXXX`)
+4. Update the key in `simple_counter.py`:
+
+```python
+# Replace with your actual Aptabase app key
+app = CounterApp(app_key="A-EU-XXXXXXXXXX")
+```
+
+## 📊 Tracked Events
+
+The app automatically tracks:
+
+### 1. **app_started**
+Sent when the app launches.
+
+```python
+{
+  "event": "app_started"
+}
+```
+
+### 2. **button_clicked**
+Sent when "Click Me!" is pressed.
+
+```python
+{
+  "event": "button_clicked",
+  "action": "increment",
+  "count": 5  # Current counter value
+}
+```
+
+### 3. **counter_reset**
+Sent when "Reset" is pressed.
+
+```python
+{
+  "event": "counter_reset",
+  "previous_count": 10  # Value before reset
+}
+```
+
+### 4. **app_closed**
+Sent when the app exits.
+
+```python
+{
+  "event": "app_closed",
+  "final_count": 7  # Final counter value
+}
+```
+
+## 🎮 Usage
+
+1. **Start the app**: Run `python simple_counter.py`
+2. **Click the button**: Press "Click Me!" to increment (or press `Enter` when focused)
+3. **Reset**: Click "Reset" to set counter back to zero
+4. **Quit**: Press `q` or `Ctrl+C`
+
+## 💻 Code Structure
+
+```python
+class CounterApp(App):
+    def __init__(self, app_key: str):
+        # Initialize with your Aptabase key
+
+    async def on_mount(self):
+        # Start Aptabase when app starts
+
+    async def on_unmount(self):
+        # Stop Aptabase and send final events
+
+    async def on_button_pressed(self, event):
+        # Handle button clicks and track events
+```
+
+### Key Components
+
+**Aptabase Initialization:**
+```python
+self.aptabase = Aptabase(
+    app_key=self.app_key,
+    app_version="1.0.0",
+    is_debug=True  # Shows debug info
+)
+await self.aptabase.start()
+```
+
+**Tracking Events:**
+```python
+await self.aptabase.track("button_clicked", {
+    "action": "increment",
+    "count": self.counter
+})
+```
+
+**Cleanup:**
+```python
+await self.aptabase.stop()  # Flushes pending events
+```
+
+## 🔧 Customization Ideas
+
+Here are some ways to extend this app:
+
+### Add More Buttons
+```python
+yield Button("Increment by 5", id="btn-plus5")
+yield Button("Decrement", id="btn-decrement")
+```
+
+### Track Time Between Clicks
+```python
+import time
+
+self.last_click = time.time()
+
+# In button handler
+time_since_last = time.time() - self.last_click
+await self.aptabase.track("button_clicked", {
+    "count": self.counter,
+    "time_since_last_click": round(time_since_last, 2)
+})
+```
+
+### Add Keyboard Shortcuts
+```python
+BINDINGS = [
+    Binding("space", "increment", "Increment"),
+    Binding("r", "reset", "Reset"),
+]
+
+async def action_increment(self):
+    self.counter += 1
+    await self.aptabase.track("keyboard_increment")
+```
+
+### Save High Score
+```python
+self.high_score = 0
+
+if self.counter > self.high_score:
+    self.high_score = self.counter
+    await self.aptabase.track("new_high_score", {
+        "score": self.high_score
+    })
+```
+
+## 🐛 Troubleshooting
+
+### "Analytics unavailable" message
+
+**Cause**: Invalid app key or network issues.
+
+**Solutions**:
+1. Check your app key format: Must be `A-EU-*` or `A-US-*`
+2. Verify network connectivity
+3. Check Aptabase dashboard status
+4. Look for error details in the console
+
+### Import errors
+
+```bash
+ModuleNotFoundError: No module named 'textual'
+```
+
+**Solution**: Install dependencies
+```bash
+pip install textual aptabase
+```
+
+### App won't start
+
+**Check Python version**:
+```bash
+python --version  # Must be 3.11+
+```
