Todoist: To Do List is a functional and easy to use task manager with the ability to synchronize things to do with other devices, share tasks with friends and display notifications. The program is suitable for both saving the list of purchases and managing complex projects. The free version of Todoist allows you to create projects, assign tasks with different priorities to each of them, share projects with friends, and assign selected tasks to different people. In addition, you can discuss tasks and add more information to them in the comments. Each task can be scheduled for a specific day - in this case the programs associated with the service will remind you about it. You can also use labels, colour codes and a search engine. Importantly, the programme uses a very natural way of giving dates and can remind you that "you have to shop on Monday". Task lists are automatically synchronized with the cloud and between devices on which applications or browser extensions will be installed. You can also print or browse them on Todoist.com. You can also see your productivity on the chart thanks to the Todoist Karma function. The program can be operated both by clicking and shortcuts. Todoist account is free of charge, but you can buy a subscription to it, which expands the possibilities of cooperation with others, allows you to add files to tasks and gives you more opportunities to receive notifications about new comments and assigned tasks.
