Niantic announced that players around the world running iOS 11 on iPhone 6s and newer models can experience AR+ in Pokémon GO. With AR+, Pokémon are now fixed to a point in space, meaning you can walk up close to a Pokémon to see to how they’ll look in the real world. Pokémon will run away if they become aware of the Trainers getting close. An awareness meter will appear next to the Pokémon, and if the meter fills up, the Pokémon will flee. If it does, you can try tapping on the tall grass nearby, which may cause the Pokémon to reappear and give you an additional chance to catch it. You can sneak up close to earn an Expert Handler bonus.
