Megan Ellis discovered TickTick in 2018 and found it to be an indispensable productivity tool, particularly due to its user-friendly interface and simplicity, which is important for users with ADHD. TickTick allows users to start adding tasks immediately without account creation and offers flexibility in organizing tasks into separate lists. The app's notification system keeps tasks visible without overwhelming the user, and the snooze feature helps manage time effectively by allowing users to delay tasks. Ellis has chosen not to subscribe to TickTick's premium plan, believing the free version meets her needs, although the premium offers additional features for a competitive annual cost. She acknowledges alternatives like Todoist, Google Tasks, Microsoft To Do, Any.do, and ClickUp, but still considers TickTick the most comprehensive solution for her task management.
