Runners-up
Reminders provides what it’s called the best: reminders. As a to-do app it’s capable yet rough around the edges.
THings by Cultured Code is a true to-do app, though you need to fully buy into its system to completely reap the benefits. Apple’s Reminders is so thoroughly tied into iOS (and macOS) that it provides invaluable integration support from other apps and the system itself.
