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.
