Not more lag
I’m amazed by its speed! Give it a shot and you’d realize how much time you’ve wasted on the original Facebook app. I’m sure this is NOT a hacker app like other reviewers suspected (although some of those reviews are hard to follow because of problems in grammar and typos; I tried my best to comprehend). However, I’d suggest following the original Facebook iOS app design to leave the menu bar at the bottom, and changing the app icon (three figures in white… look suspicious).
