At long last, Pokemon Go has released a long awaited update.
If you still play, you are aware of a (now released) new update. This update let's you partner up with a "buddy" and earn rewards.
Well, that update is out, for Android, and you can start earning those rewards. As far as I know, that is simply candy right now, which is handy for rare Pokemon, like starters.
To do this, click your player image in the corner, this will bring you to your Player Profile. Click the 3 bars in the right hand corner and select "Buddy", then you're all set.
Of you change your buddy, you lose current progress, so keep that in mind.
An Apple update is incoming, so just hang on right and get prepared for lots of walking.
