iOS vs Android specifics

A few differences between the two versions:

• iOS: no alternative APK possible. Apple requires going through the App Store. If your country is restricted on the App Store, you have to use the web version.
• Face ID / Touch ID: available on iOS for biometric login. On Android, it's the phone's fingerprint sensor or facial recognition.
• Notifications: fine-grained notification management is more detailed on iOS. You can choose by category (resolutions, disputes, news) in Settings → Ktkarena → Notifications.
• Storage: the app takes ~95 MB on iOS, versus ~80 MB on Android. That's due to the heavier Apple frameworks.

What to do if something goes wrong

"The app doesn't show up in the App Store":

• Check that your Apple ID country matches a country where we operate (Cameroon, France, Belgium, Senegal, etc.). If you're registered in an unsupported country, you won't see the app.
• If needed, change your Apple ID country in Settings → [Your name] → Media & Purchases → View Account → Country/Region.

"Download stuck":

• Check your connection (WiFi/4G).
• Check that you have enough space left (~200 MB free minimum).
• Restart the iPhone and try again.

"The app refuses to launch after installation":

• Very rare, but possible if your iOS is very old. Check that you're on iOS 14+.
• Uninstall and reinstall.
