Apps like this have the potential to make reading a chess book way more convenient, because you can always see the current position.
This is a good start but it’s just a beginning, it needs more work.
As far as bugs are concerned, it does not remember correctly the location on the page when restarting LearnwithForwardChess . On a chapter with ~ 10 games, it’s not easy to find the place to continue.
Also, it loses the current position when double-tapping to go full screen (or return from full screen).
In terms of features, the main thing I miss is some kind of visual indication that there’s text to read after the current move. Imagine I watch the board and then tap the Next button to advance through the game. Unless I check the notation after every move (very distracting) I would miss the move comment. True, there’s a dialog for variations, but that’s not the same thing. Some commented moves don’t have variation. A change in color, some dot lighting up somewhere would mean a lot in terms of convenience.
