Pokémon Quest is a Pokémon game, and as such, evolving your Pokémon is a big part of the game. Evolve them to increase their HP and attack significantly. Like in the original Pokémon games, you can evolve any Pokémon by hitting the right experience level, but unlike in the originals, you dont need any evolution stones or special items; however, there is a different method for evolving Eevee into one of its three evolved forms.
