TickTick is a productivity app designed to help people organize tasks, plan their time, build habits, and stay focused. Its to-do lists support work projects, personal responsibilities, and study plans, while calendar views—from yearly and monthly to weekly, daily, and agenda formats—make it easier to manage schedules. Users can also track habits, record important dates, and apply tools such as the Pomodoro timer, Kanban boards, timelines, and the Eisenhower Matrix.

The app includes reminders, recurring tasks, natural-language date recognition, customizable filters, keyboard shortcuts, and progress statistics. AI features support voice-based task capture and turn recordings or notes into transcripts and summaries. TickTick also offers collaboration through shared lists and task assignments, plus calendar subscriptions and integrations with other apps. Its services are available across phones, computers, tablets, and watches, with real-time synchronization. Users can personalize their workspace with more than 40 themes. TickTick offers a free version and a Premium plan, including discounted pricing for eligible students and educators.
