I can see why they have a halo app. It would be useful for on the go stuff you would do on waypoint. The only thing is, it's super buggy. For example, everytime I try to look at one of my games or one of my friends games, it shows someone in my Spartans company's games and that's the only person it would show! I would use this app more if it were fixed because right now my laptop needs to be replaced and I need to use waypoint!
Extremely buggy(for me)
