Can't set multiple: android and windows phone:(
@MikeKosulin Hi Mike, so far we're only available on Android, so we're asking your phone OS because we need to know whether we can send you your invite outright!
In your case, we can :)
Then if you want us to also put you on our Windows Phone list for later, you can send us an email to hello @ and we'll gladly do so. Hope that helps!
