Todoist is great at attacking shallow work, the ones that brings death by a thousand cuts. Design is not upto par with Things 3 and key concepts are missing like start date and duration of a task but its integration with third party apps, solid API and task URLs for deep linking are unmatchable.
Overall, its a reliable app that doesn't break.
The Best, Nothing is even a Close 2nd.
i have been using it for 10 years now.
having tried most apps. Their team and focus on the product is as good as Apple
I have a few favorite to-do apps, but my top pick is Todoist. It's a simple, yet powerful app that helps me stay organized and on track. I like that it's easy to use, but it also has a lot of features that I find helpful, like: Customization, collaboration and integrations.
