What's a good iOS app for keepin' track of my games and messagin' my buddies when I'm on break?

Look, I ain't gonna lie, the Xbox app ain't perfect. The tutorial's useless, like most of 'em are these days. But once you figure it out, it's actually pretty damn useful. I use it to see what my buddies are playin' and send 'em a quick message to hop on after work. It's built like a brick house, too; dropped my phone twice on the job site already and the app still works fine. Battery life ain't great if you're usin' it all day, so keep a charger handy. But for checkin' in on my games and stayin' connected, it gets the job done. No BS, just works. Rain doesn't stop it either, used it under the awning during a downpour last week.
