I’ve used Things3 as my task manager across all my devices for years but the recent issues nudged me to check the current state of Apple’s Reminders app. It is much better than years ago so I’ve dumped Things. Reminders has a great, natural, method of integration with Notes and also works more seamlessly with Siri. It is all made better by the windowing on iPadOS 26. Less friction is a happier life.
