Disappointing.

This app is consistently rated as one of the top crossword apps but it has stability issues on multiple iPads (Retina, Air 2). Switching to and from the app causes the grid of puzzles to freeze or show a blank screens. Frequently puzzles in progress will be displayed in the grid of puzzles as all black. The only fix is the kill the app and restart it. It’s been this way for months so if this is the best app for crosswords on iOS, I’m can’t imagine what the other lower-rated ones are like.
