User Reviews and Ratings
★★★★★Komodo
Perfect app inlove this komodo chess engine
★★★★★Retired thinker
I like the flexibility to control moves and then go back to the program making the moves Very good instruction while playing.
★★★★★Excellent update
New computer play mode with move now is great. I can play a line out or just make computer move rather than making it's moves to see next move. Updated book is nice for some lines that had poor coverage in the old book. Maybe more book updates can be done in the future.
★★★★★Very solid app
I have been looking for an opening app for a while. Finally I feel I found it. It is great! Gives user a lot of freedom to try out and save moves.
Constructive feedback
— some features are not intuitive such as saving games.
— somehow ability to save different lines of same opening is missing
— I am yet to figure out color coding scheme and what is the purpose of importing other games
But regardless a wonderful app. Thank you
