Make the app customizable and easier to use
Every category needs to be fully customizable. Quests, powerups, badguys, and the content therein need to be made easy to delete, add your own, and clarify your goals for context.
Furthermore, the interference is not clear and could use a serious remodeling.
Lastly, the app is buggy and crashes frequently.
I am well into the book and would really like to use the app. I'm using a similar app called Coach.Me. I would love if SuperBetter was SuperBetter

I agree, I came here to suggest that you should be able to add power ups from different power packs without having to add the whole power pack, but that goes for everything... quests, bad guys, etc.
