The Pokéwalker app is an Apple Watch app that uses your steps to hatch, level, evolve, and gigantamax Pokémon. It was developed in swift using xCode and utilizes local notifications, background refreshes, watchface complications, and healthkit data to deliver an experience akin to the old Pokéwalker from the HG/SS era of Pokémon.
