The best task manager for Mac and IOS
After a lifetime of Outlook task management, I struggled to find a decent task manager when I started moving to Mac products. This is the best I have found, and it does everything I need it to. You can set up tasks as projects with subtasks including checklists, there is so much flexibility in how tasks can be tagged and organized that it will fit the way anyone works.
There is a measly $20 a year charge to keep your tasks synchronized across all devices. I continue to be shocked at people who balk at paying a nominal fee for an excellent product, perhaps its all of my years as a PC user spending hundreds of dollars on software. This product is as good as it gets.
(update November 2015) I had some trouble with ToDo Cloud after upgrading to El Capitan and the support was fantastic. They sent me their beta to try which solved the problem, and were super responsive. This is still the best app out there.)
