Evolving Pokémon is an essential part of , and, for some Pokémon, the Friendship Checker will play a crucial part in this process.
Building a good relationship with your Pokémon is important, not only for battles, but a handful of Pokémon can only evolve if their friendship has been maxed out.
Unfortunately, the Friendship stat is not one that players can check for themselves until they have unlocked the Friendship Tracker.
This tracker app will eventually become available as part of the Pokétch. Along with the other available apps, you will be able to view how far along you are with every Pokémon in your party, using your Pokétch.
To unlock the Friendship Checker, players must go to Eterna City in. This is where players need to defeat the Gym Leader Gardenia to collect their second gym badge.
