### 3/5 — Pgn can’t be analyzed

*2026-01-25*

I think the core strength of the app is the analysis like in chess.com. Why can’t you analyze imported pgn data? I want to know how good my online match was… this doesn’t make any sense. Also the UI is unfortunately very bad on iPhone still. Chess.com does this way better.

**Developer response:** Thank you for your feedback, and I sincerely apologize for the inconvenience. We have addressed both the PGN analysis issue and the iPhone UI concerns in Version 1.0.9. Now that we’ve identified and fixed the root causes, everything should work smoothly, but please don't hesitate to let us know if you encounter any further issues.
=============================================
Thank you for your honest feedback, and we sincerely apologize for the frustration.
​We hear you loud and clear—the ability to analyze imported PGN data is a core feature we want to provide. We are prioritizing this and will fast-track the development to add PGN analysis functionality as quickly as possible.
​Regarding the UI issues you mentioned: we want to make it right. To help us understand exactly where it falls short on your device, could you please send us a screenshot of the UI at contact@commonsourcelab.com? This will allow us to pinpoint the display issues and ensure our improvements meet the standard you expect.
​We are committed to making our analysis tools as robust and user-friendly as possible. Thank you for your patience as we work to improve.
=============================================
Thank you for your valuable feedback! We sincerely apologize for the inconvenience you experienced. 

We are pleased to inform you that the requested features and improvements have been implemented in version 1.0.8:
• Added PGN import functionality so you can now easily analyze your games.
• Optimized the Game Review UI specifically for iPhone 13 to ensure better readability and display of multiple items.

Please update to the latest version and let us know what you think. Thank you for helping us improve!
