TickTick Free provides several planning tools within a defined capacity. Organize lists around lasting responsibilities, then use tags and dates for detail so the limited number of lists is not consumed by every short-lived activity.
Use the nine-list allowance for stable areas of responsibility and avoid creating a new list for every short project. Add dates only where they represent genuine commitments. Review the habit and reminder limits before making TickTick the sole place for a more complex planning routine.
