I don't think you can install the android apk on an Apple. Dowbload the Apple version and follow the installation instructions...

Theres no iPhone version. Unfortunately, iphones are way too locked down so there's no way to get games on them easily. Every app/game has to be approved by Apple to be downloaded, so they don't let you download anything that's not in the app store.

Apple uses .api files for iPhones, and not .apk ones. even if the files in here were .api files, you'd have to download them on your computer, and use an injector (computer software meant for developers  that installs software on your phone to test your code, illegal to use if you are not a developer that is aproved by Apple).
