Complete Reminders from a Widget
Reminders’ widgets feature an attractive design, but one of their biggest limitations is that they’re mostly just for looking at your reminders. While you can tap on an individual reminder to be brought into the Reminders app, you still have to complete it manually when you get there.
That changes in iOS 17. Widgets are becoming interactive throughout the entire operating system, and Apple has chosen to use Reminders as one of the best examples of how useful this can be. Now, tapping on a reminder in any widget will immediately mark it as completed — without opening the Reminders app. The completed reminder will remain for about a second in case you change your mind before smoothly disappearing from view.
Naturally, Reminders is the only app that supports this right now, but Apple has opened interactive widgets to third-party developers, so you can expect all of the other popular task management apps to add support after iOS 17 is released in the fall.
