I'm an ARK: Survival Evolved fan and I'm currently developing this guide so other fans can have access to information about the game. This app is in not official and I'm not related in any way with Studio Wildcard (and the rest of games's developers).
ARK Guide is on alpha version.
This app is a guide that contains all game engrams. They are sorted by level an you can see the description, necessary points and explanation.
I am working to make a better guide, but I need time.
If you have some commentary please send me a email.
