I own 42 Forward Chess app books. The app is far better than any of the competitors. I use it mostly for a “guess the move” approach to the study of grandmaster games that are well annotated. On the iPad, I use landscape mode so the moves and annotations are in the right side of the screen. I hide that part of the screen while I play through the game using the right arrow to make the moves. I guess the best move before seeing what the grandmaster played. After going through the entire game in this manner, I go through it a second time to play through the annotations. Forward Chess is the only app that fully supports this type of powerful training.
Forward Chess has become one of my favorite chess apps ever! The ease of use and the variety of book titles makes it an invaluable resource for any serious chess player. The ability to study openings, middlegames, and endgames on my phone, tablet, or computer makes studying chess easy and accessible with a busy lifestyle. Forward Chess is how books should be studied in the 21st Century. Thanks for all the work you do!
