This space is open for discussion on the nature of my post regarding iOS lock screen features and what should or should not be there.
Part 1 involves the issue of security. Share your thoughts!
While I agree, in principle, that having such actions could potential breach your privacy, I would argue that the threat posed by these is not always enough to be of concern. If an application directly affects how the user perceives the Lock Screen, in such a way that even a novice user would notice something amiss, then that would be a problem. However, if the application is more passive and must be invoked by an Activator command, choosing an obscure Activator command would lessen the chances of someone stumbling upon it. So, while biteSMS' "Tap to Compose" prompt might be a problem, double tapping the left of the status bar wouldn't be so treacherous.
Some might offer that, regardless of how obvious the command is, an onlooker would see how you invoke it. To this, I would remind them that, if they could view that command, whatever it may be, then they would be able to easily see and temporarily commit to memory your passcode, assuming it is short enough and purely numeric, as most are. If, on the other hand, you do not have a passcode, then arguing about the security of the Lock Screen is pointless.
Those are my thoughts. Personally, I invoke CallBar, biteSMS and even IntelliScreenX on Lock Screen without worry. The first two are sufficiently hidden, and I have nothing to hide in my Notification Center.
Thanks for your feedback! Team Branch
