If you would like to change your Trainer nickname, you can change it within the Settings menu. You can only change your nickname a limited number of times, so choose wisely. Keep in mind that your nickname will be displayed to other Trainers.

To change your nickname:
  1. From the Map View, tap the Main Menu
  2. At the top right, tap Settings
  3. Tap the Change Nickname menu option

Note: If you cannot see the Change Nickname menu option, you have already redeemed all available nickname changes.
