Much too easy. On my first puzzle I knew virtually every clue, and many of the clues are practically spelled out for you. I mean honestly, what sort of clue is this: "A sport that can be played individually or in teams, that is played in water, and which Michael Phelps is associated with." Seriously? I think if you're a little new to crosswords, or to English, this is maybe an ok app. Experienced crossword puzzlers should probably avoid it.
