The popular SubtleLock
jailbreak tweak for iOS devices has been re-released for iOS 8. The tweak focuses on minimizing the footprint of Lock Screen elements so that there is more room for viewing of the wallpaper and notifications rather than wasting space with a huge clock and a poorly-positioned slide to unlock text.
SubtleLock (iOS 8)
by iOS developer Michael Poole is available in Cydia right now for iOS 8 users that wish to follow the minimalist tradition.
