This app features the latest Pokemon Go events news and a complete Pokédex as well as various functionalities which enhance the connection with the Pokemon Go Plus the Pokeball Plus and the Go-tcha accessory.

Some of the accessory features are:
• A connection boost which reduces the lag between the user input (button press) and the game recognizing it
• A reminder when you lose connection to the accessory
• A valued percentage of the battery left in your accessory
• A statistic feature which keeps track of everything your accessory is doing

These are just some functionalities of GO Companion and more will be added in future updates!
