Unfortunately it's only created for iOS. While Samourai Wallet is good wallet, some people prefer Wasabi CoinJoin (mainly because it's more popular CoinJoin option).
Unfortunate for the Android users indeed. But I assume that's why they did iOS first, it's simply because iOS users don't have a privacy-focused wallet yet. And since it's really really early as it's still in beta, prooobably they'll make an Android version once they done the iOS full release.
Feel free to talk to them on Twitter or on the /r/WasabiWallet/ subreddit as they seem pretty responsive.
