Note-taking is an incredibly useful way to ensure you don’t forget something later on, and while Apple’s Notes app is a great tool for jotting down a note here and there, it can be a nuisance trying to get to the app in a pinch when I need it.
Libellum is a newly released and free jailbreak tweak by iOS developer LacertosusDeus that offers refuge from the aforementioned qualm, and it does so by putting a convenient note-taking widget directly on your Lock Screen that you can interact with without any delay of any kind.
