So far I don't know how to solve one problem there, but I'm open to ideas! It's very easy to inject fake fitness data in both of those platforms. With CoreMotion, iOS/watchOS give you a lot of inherent anti-cheat for free.
Note that the walkthrough system is very new and finicky, and I'm rewriting AI slop copy by hand as I get farther through the story. I update on average more than once a day. Have a look, and feel free to email ben@yourstrategy.co if you have questions or feedback, I'd love it!
