Todoist

Todoist has been around for quite a while now, and as long as there are productive people in the world, it’s not going anywhere.

Todoist is a great app that can be used on your Mac, your iPhone, or on practically any other platform. You can organize your life in different sections and create several reminders or tasks that you need to complete for every single one of them.

Besides its clean looks and easy-to-use interface, Todoist is everywhere, so you won’t have an excuse to miss a reminder or skip an appointment.
