Chess-Studio

Outstanding app for database management, training, analysis, building a repertoire or just having a quick game with Stockfish. Not a big learning curve, and if you’re familiar with chess database programs this should all be pretty easy to get around. Links directly to PGN Mentor & The Week In Chess for access to literally millions of games to build a database with, and you can import your own. Easy navigation of bases (player, year, event, ECO or combinations of those & other parameters) & a boat-load of various analysis & search functions including endgame tablebases. Also ability to create custom opening books for stockfish to use from databases is a big plus! If you’re serious about chess, or want an easy to use, stable program for OTB prep, this is probably all you’ll ever need. Highly recommended.

The description says, “For serious chess players,” and another review states “If you get one chess app, make it this one.” Both are true. Other chess apps have lots of eye candy. However, when it comes to what it takes to manage your repertoire, analyze your games, and other important functions you would expect from a chess app for anyone who is half-way serious about their games, then _nothing_ on the App Store comes even close to Chess Studio: Manage your PGN databases, analyze, create opening tables, download from TWIC and PGN Mentor, … Yes, it has its interface idiosyncrasies and its own way of doing things but one will easily get used to it and understand the rationale behind its presentation. I especially like how the analysis (now using Stockfish 16) shows immediate graphic feedback with labeled arrows with different transparent colors akin to Nibbler/Lc0. This is a fantastic app for importing games played on either iPad or iPhone and analyzing them. Easily move PGN databases between iCloud, DropBox and local storage. Create opening books from your games on mobile? Unheard of, but this app does it! The more I use it, the better it feels. I cannot thank the author enough for such a useful and functional chess app!

I’d say 10 Stars or more. This is truly a One of a kind app. From beginner to advanced, this has it all. It’s a great chess playing app with a Stockfish 15 chess engine. Save games on your iPhone or iCloud or Dropbox. Use iCloud to import thousands if not millions of games from PGN Mentor and other chess sites. Create your own database’s, merge them and study the great masters. You can create variations, comments and move ratings. Use markup to create different color arrows and boxes, great for analyzing the great masters as well as your own games. You can also creat your own Opening Books. There are just too many things to mention here. Truly, this is well worth the money. I would pay 20x more and be very satisfied with the purchase. You have to use it to believe it. I would keep going but my finger is getting tired. GET THIS APP.
