The ultimate pokemon go game for andriod phones

So, I have been searching for a good pokemon go and so far I have come across hundreds of games. I really want to give this game a try as it is the talk of the town these days. So, can someone tell me the name of really good pokemon go game? I have tried searching but there are so many guide apps, tips and tricks, forest pokemon go games...that I can't just decide on just one game. I don't wanna give much space to games ad I want to have as much anime as I can in my smartphone, tablet and laptop.

So, can someone help me in installing a very good pokemon game?
