One of the gripes I have about the iOS lockscreen is the fact that apart from being able to launch the camera app directly from it and some media controls, there's not a lot I can do with it. It's a different story with Android due to its customizability, with some lockscreens allowing user to launch a variety of apps directly from the lockscreen itself, or having the lockscreen display information like the weather which saves time from having to launch the Weather app AFTER unlocking our phone.
