TickTick

easy to use and has everything you'll ever need.

Sorry but without a lifetime pricing I'm 100% out,I can't recommend this app.

Excelent

One of the great TODO app, i have ever used.

Great app for tasks and habits

my favorite task manager. to do's + calendar + pomo = killer combo

I am still not sure whether having habits and pomodoros (I use Pomo for specific recurring activities) in the same app where todos are, however, TickTick got me, a seasoned productivity geek and a project manager, to a whole new level of control.

great app, has paid plan but it's worth it - allows to have merged views for calendar & tasks, good tagging and quick capture options

Amazing cross-platform productivity tool. Should work on customer service but the API integration is amazing also.

Pretty good overall, but UX can be improved.
