The best remote working tool I could recommend is Todoist. At DealsOnHeath we use it.
Todoist is a powerful task management tool that can be both used for personal and professional use. Furthermore, it can be just a simple task manager or a robust collaboration tool for remote teams.
As its name suggests, Todoist is a software that allows individuals and teams to keep their to-do lists in one place, enabling them to plan their day better and avoid missing deadlines. Remote employees are especially in danger of dragging their workday, and Todoist will help them add a structure to their day by allowing them to prioritize things they have to finish.
What I love about this software is the feature that allows users to break bigger tasks into small, more manageable chunks as well as to see and track productivity levels throughout the week.
If we talk about pricing, Todoist comes with a free plan, which is good for those who consider trying it. And paid plans are budget-friendly too: premium starts from $3 per month. The business plan is only $5 per user a month.
