How we tested

We have focused on the Mac versions here, though all these apps have iOS companions so additional costs and ease of syncing were also considerations. Setting up multiple smart lists, reminders; tags; and, where available, sequential tasks and subtasks, we set up and ticked off a range of personal and work-based tasks. Email-to-task, voice input and collaboration with other invitees were all tested where available in an app, and the overall ease of use and efficiency of workflow was also factored in to our reviews.
