“SHERLOCK: Interactive Adventure” available on the App Store
An app which will make you look at interactive books in a whole new light
The app tries to get the book alive with interaction which include:
30 plot-based scene
Interactive map of London 19th century
You can download it for free but not everything is available if you want everything you can buy in-app.Download: https://itunes.apple.com/us/app/sherlock-interactive-adventure/id820860824?mt=8
Although I like the app itself they didn’t succeed in a couple of things. Go find out yourself and give a comment.
