content: Have been using for 3 years. Very dependable. Due to my own discipline I have had periods where I used this daily and periods months where I didnt open the App. When I am using the App I work better I feel more in control  I accomplish more of my priorities. Over a decade ago I used Outlook Tasks constantly. The only feature where TickTick does not meet the old Outlook task is that TickTick is designed to have a single date associated with a task called a due date. I use the Due Date as a start date. TickTick is less flexible in building special reports based on both start date and end date for a task. I think of tasks always as having a start and an end. When you use the duration in the paid for version it is still complicated as TickTick does not provide easy ways to create custom reports and smartlists using StartDate and EndDate. Other than that this is a fantastic app that allows you to create lists of tasks I use as Projects have a 4 level priority system which I no low medium and high priority but I use as lowmedium priority no  High Priority  TODAY  and NOW . This way I can easily signal what one to three tasks I am working on Right Now when I get disrupted with another call it is easy to redirect myself. Great app. I gladly pay for it so they can continue to support the app and improve it  and I get the value out of the app. I have looked around for better todo list apps multiple times and never found anything better short of going fully back to Outlook to manage my emails and calendar which I do not plan to do.
