Epic has posted a list of Frequently Asked Questions and answers over on reddit to try and clear up some of the common questions surrounding Fortnite mobile. Here they are:

Q: How do I sign up to play Fortnite on mobile?
A: You can sign up at http://www.fortnite.com/mobile.

Q: Where can I find more information on Fortnite coming to mobile?
A: You can read more on our blog at http://www.fortnite.com/news/mobile-announce.

Q: When can I play Fortnite Battle Royale on my iOS device?
A: Once the event begins and you receive an invite. Invites will start rolling out soon to players who have signed up.

Q: Why haven’t I received an invite?
A: We’re sending out invites as our services scale up to handle more players with the goal of maintaining a healthy player population. Not everyone will get in at the same time. After you sign up at www.fortnite.com/mobile, you will be notified via email once you get in.

Q: My friend received an invite and they signed up after me, what gives?
A: Factors that contribute to the order in which players receive invites include sign-up order, proximity to a data center, and device model. If your friend got invited by Epic, check with them to see if they have a friend code to share with you.

Q: Is Fortnite on mobile coming to Android?
A: Yes. Android will be supported in the next few months.

Q: What iOS devices are compatible with Fortnite on mobile?
A: To participate, you’ll need an internet connection and iOS 11 on at least an iPhone 6S/SE, iPad Mini 4, iPad Pro, iPad Air 2, iPad 2017 devices or later.

Q: Will Mobile players be forced to play with other platforms?
A: No. By default, mobile players are matched against mobile players only. When a mobile player joins a squad with friends on other platforms, then that squad is matchmade against a multiplatform population. Thus, cross platform play is opt in.

Q: I got an invite, where do i download the game?
A: In the invitation email, you will receive a link to download the game from the iOS App Store.

A: Yes. As soon as we are able to handle the scale of players, the game will be open to everyone.
