It's been really useful for me, I wanted to start losing some weight and it was a good motivator to start walking. Plus I just met a few people in my sixth form that play, so on community day we went into my city to catch those metal bois
I wanna use PoGo when I walk to get them buddy candies/etc but I find it's not the best activity tracker. Plus it drains the battery a smidge. I guess I could use it on my apple watch though
