I always see little comments on Facebook or here about FB needing an app. But I feel like they already do! I put a shortcut to their site on the home screen of my phone - which is like having an app there - and the website on a phone works almost exactly like an app to me. It takes so much upkeep to run an app, so I just thought I'd say.... I'm happy without! If one ever got developed then sure, I'd have it, but I'm happy now anyway!
