BUILD YOUR OPENING REPERTOIRE

Add your favorite opening lines to your repertoire using the chess opening explorer or import your openings in PGN format from other chess programs. You can always edit the names of your openings and organize them in your repertoire.

OPENING TRAINER

A simple and efficient method to memorize variations of openings in your repertoire. You can train either white’s moves or black’s moves only or both. Optionally, you can train all variations at once. The trainer chooses the opponent’s moves randomly from your opening repertoire. Chess Opener tracks your progress and shows your stats.

Ratings and reviews

I would say that this app technically does what it promises. However, it is no substitute for... anything. If you want to add an opening to your repertoire, read the Wikipedia article, buy a book, anything. This app is next to useless. Not worth any money whatsoever. There's no description of the ideas behind openings, there's not an option to really train anything beyond the first few book moves, and the "grandmaster openings" are a joke.

So far, this looks like the best chess opening app I have tried. My needs are simple: a premium app that lets me buy it once and not pay a monthly fee, the ability to add any openings I want to practice, and a non-annoying interface that preferably allows customization. If it has a built in database and engine, that makes it basically perfect. This one has all of those things, so great! My only wish is for more theme customization, since I am not a fan of the colors. Still, it works fine for me!

Pros: Single payment, affordable price. User-friendly simple interface. Reasonable opening database. Access to GM repertoire. ~~~ Cons: Very slow engine analysis; very frustrating, you'll need to export the position to a different app to run analysis. Cannot edit the variations after imported. No visual animation or coloured arrows. Large app >105MB.
