No iPhone app yet
Ktkarena doesn't have an app for iPhone yet, nor for iPad: you won't find it on the App Store. The app only exists on Android, in beta, and downloads from the site (Download the app on Android). An APK file, the Android app's format, doesn't install on an iPhone.
No release date has been announced for an iPhone app.
In the meantime: the web version
Ktkarena's web version opens in your iPhone's browser (or your iPad's):
- Open Safari, or another browser, and go to app.ktkarena.com. The "Log in" button at the top of ktkarena.com (in the menu on a phone) takes you there too.
- If your account has a password, log in with your email address and that password. An account created in the app has none, and logging in with a code received by email only exists in the app: log in with "Continue with Google", using the Google account with the same email address. If your account isn't linked to Google yet, this first login links it and logs out your other devices. Without a Google account on that address, write to support@ktkarena.com.
- No account yet? Tap "Create an account": you choose your username, your email address and your password, then you accept the Terms.
It's the same account as in the Android app. The web version, though, doesn't send push notifications. Details: Using the web version (on a computer).
