Plays just like the board game, and is easy to learn how to use. However, . . .
The online multiplayer setup is poorly organized and managed, particularly with the Stone Age league. You cannot choose your opponent, and you cannot select a time frame for the game you want to play. So a person who wants to play a relatively quick game can be matched against those who want to play a game that lasts for days or weeks. But the biggest problem with the league is that there are glitches. Sometimes, you are unable to play your turns, games are mistakenly resigned, and your player rating gets messed up. I recently lost a game in which I was unable to play my turn for several days, and my rating was dropped way more than it should have been. So after gradually climbing to the top of the leader board, I was bumped way down for no reason. So needless to say, I am done with their "league."
The other annoying thing is that Campfire Creations never responds to emails, so when problems arise, they dont do anything about it. So if you want to play against the computer or friends, or if you do not care about player ratings, the app is ok. But if you want a better experience, get either Agricola or Lords of Waterdeep. Playdek is a far superior company, and these are better board games anyway.
