Decent App with the Features that Players Need


This app has the best combination of features I've found so far. I love using it. And the developers seem attentive to making fixes.

I've discovered a few problems:

1. I wish there was an easy way to add .pgn and .txt files to an existing database. Either allow the copy of some or all of the games so they may be pasted to a database, or better yet provide an "Add File to Database" function.

2. The app does not properly interpret braces or ellipses which contain comments or variations. Maybe the apps' pgn standard needs to be expanded because other pgn programs read these files correctly.

3. There are a few mispelled words such as "Reasearch" which is correctly spelled "Research", etc.

Hi Zugzwang,
thank you very much for your review. Could you be so kind to send me by email the problem you have discovered at In this way we can better interact each other. Thanks and regards, Giordano

Best PGN app in the store!


It’s astonishing that for a such a simple task like viewing PGN games I was not able to find a good app in the store until I found this app, It is awesome you can easily go through books and games with analysis from grand masters, unlike most of the other chess apps this is updated for iPhone X, keep up the good work!

Great developer


Some Dropbox issues on earlier ios but there's a workaround, just contact developer--very responsive. Sounds like a fix is forthcoming also.
