This tweak has a lot of known bugs that need to be worked out during the beta testing, and since it changes the way the phone unlocks, it's a good idea to set up an activator gesture for unlocking as a backup.
I've been a user of the UnFold lockscreen for quite some time, but now I've disabled it in favor of JellyLock. Like its inspiration, Android Jellybean, JellyLock features a circle lock icon that expands when touched to a larger circle. You can drag to the edge of the circle on your Lock screen to unlock your device. It also features the ability to fully customize the look of the launcher and add up to six custom apps that can be launched directly from the Lock screen. Other customization options include circle size and position, labels, badges, Siri launch, opacity and vibration.
Although it is still in beta, it seems to work just fine.
