I'm going to buck the trend, and say I'm really liking the new tracker so far - with the caveat that I've mostly got to play with it in areas with relatively abundant pokestops! I have found the triangulation sightings tool profoundly frustrating to the point of just never wanting to open it - with this, I can see that the precious Eevee is at the Pokestop behind me, and decide whether or not I care enough to turn around and walk back for it or not, but the rest of my game play is unaffected. It's also giving me a glimpse of what the nest re-jig has done for my local park (which is my nearest play area, but the opposite direction from my house than my route to work) so - that's my plan for tomorrow's walk, then! (Growlithes!)
