Scrivener

It’s not often that a sequel is even better than its predecessor, but Scrivener 3 is a great example. Version 2 was already good, winning MF319’s group test, but version 3 adds so much. Its revamped interface is hugely customisable, its templates are fantastic, managing footnotes is a breeze, and the whole app is light and speedy. If you write, Scrivener is absolutely essential.
