Pokémon GO's recent uptick in members means that many new players are finding themselves overwhelmed by the number of items found in the game. While the game does give a brief overview of the items and their uses, it takes strategic thought and additional research to ensure that the items are being used to their fullest potential. Whether you're new to the game or have been playing since the game's release in 2016, it can be easy for players to miss out on various opportunities if they are not maintaining diligent intention when it comes to using the in-game items.
