Apple’s iPhone Duo launched Oct. 23 in more than 70 countries and regions, with another 28 markets scheduled for Oct. 30, so its release is not worldwide all at once. Pokémon GO’s App Store version history lists version 0.433.1, released Oct. 16, and does not mention iPhone Duo support; Apple’s list of more than 50 apps optimized for the foldable also does not include Pokémon GO. That supports saying the game had no publicly confirmed Duo-specific optimization at launch, but does not establish how it performs on the device or rule out an unannounced update.
