A Reddit user contacted Niantic about Pokémon GO for Apple Watch and was responsed to with bad news.
Pokémon GO development for Apple Watch has been shelved according to the response. 9to5Mac confirmed with their own source as well about the port being shelved. Given how quickly Pokémon GO Plus (their own wrist accessory) sells out, this is an interesting decision. I wonder how Apple feels knowing they gave Niantic stage time to show an unfinised port off that may not see the light of day.
Pokémon GO is available on iOS and Android.
