## Detailed Features

### Real-time Cheering (실시간 응원)

How it works:
1. A runner starts a "Live Running" session in the Pacemaker mobile app.
2. A shareable web link is generated: `https://pacemaker.run/profiles/{username}/live`
3. Friends open the link in any browser — no app install needed.
4. Friends see the runner's real-time GPS route on a map with live metrics (distance, pace, time).
5. Friends send cheering messages by tapping emoji-based cheer actions.
6. The runner hears cheering messages as voice audio through their headphones while running.

Key details:
- The live map updates every 10 seconds with the runner's GPS trace.
- Multiple friends can watch and cheer simultaneously.
- When the runner finishes, the session is marked as completed and the map shows the full route.
- If no live session is active, visitors see a redirection to download the app.

### AI Coaching (AI 코칭)

- AI coaches have unique personalities and speaking styles.
- Coaches provide real-time audio feedback during runs based on:
  - Current pace vs. target pace
  - Distance milestones
  - Time intervals
  - Running form suggestions
- Coaching is personalized and adapts to the runner's performance.

### Running Records & Statistics (러닝 기록)

- Weekly running streak
- Live running banner (if currently running)

- Monthly running calendar
