The newest Pokemon Go update – 0.37.0 for Android and 1.7.0 for iOS – is available for download. This update introduces the
Buddy system, a mechanic that allows players to choose any Pokemon from their collection as a companion.
Aside from the ability to have a favorite companion on your journey, the system also adds an additional way to earn Candies for your Pokemon Buddies. The bonus for traveling a specific distance with your selected companion is a single Candy for the chosen Pokemon.
Each Pokemon Buddy in Pokemon Go is created differently, and that separates them in different walking-distance-candy groups. For some of them, you’ll have to walk a short distance of 1 km before you get a Candy, and for the others the distance is 3 or 5 km, which makes them more difficult to acquire candies from. Horsea, for example, takes 3 km For 1 Candy, while Eevee requires 5 km.
Pokemon GO Important Notes:
- If you’re in the process of walking a buddy, swapping between different Pokemon to see how far you need to walk them will make you lose your progress.
- Another interesting detail is that walking your Buddy Pikachu 10 km will place him on your shoulder instead of standing next to you.
