The Pathfinder Adventure Card Game "Rise of the Runelords" has an iOS version developed by Obsidian. It is a very good version of one of my favourite board games. It's a free-to-play game (don't quit reading yet) with an option to "unlock everything" for ~$30. I play the iOS version on my own (there are pass and play options for multiple people), and the physical game with my kids regularly and wife on occasion. Give the free version a try, I love it!
