Answer calls like a Pokémon master with PokéCall. This tweak transforms the incoming call screen into a Pokémon battle. Contacts can be customised so you'll recognise who's calling from their trainer or Pokémon.

• Choose your Pokémon from any in the entire Johto and Kanto regions (1st and 2nd generation)
• Have trainer battles or wild Pokémon encouters
• Transform your ringtone into one of the many different battle theme songs
• Option to minimise the call screen to a banner
• Applies to FaceTime calls and third party calling apps such as WhatsApp

Buttons on the call screen are as follows:

• Fight - Answer the call
• Run - End the call
• Hide - Minimise the call screen to the call banner
• Switch - Remove the pokemon battle and restore the normal call screen

Once in the banner mode you can tap the banner or swipe down to resume the full screen call. Swipe up to end the call.
