With Vesper now shutting down, we lose a great app. It is ostensibly a notes taking app, but the excellent tagging system and the ease with which we can reorder entries manually makes it actually a free form task and thought organizer. It is this consequent replacement of folders with tags that makes it so powerful. It recognizes that folders are overkill until you are dealing with enough material to write a book.
One would have expected this to be widely copied, but sadly not. Unfortunately, the bar for a competitive notes app gets higher and higher every year, and with it the effort actually bring any innovative new idea successfully to market. Sadly it means that the chances of getting an adequate replacement for Vesper are slim unless one of the established apps decides to adopt this interaction model.
