Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
What's new in 1.0.2:
- Pick your AI coach: meet Coach Elena or Coach Max, and switch any time from Profile.
- Accept a challenge from Discord and the game opens right here in the app.
- Coach Elena now plays the real engine best move on request, and never an illegal one, and can help you on Weakness Drills.
- Fresher chess news (newest headlines first).
- Performance fixes and polish.
