Great application! I use it across all of my platforms, seamlessly. Keeps me organized for my day to day, week to week, month to month, and year to year tasks. I can attach documents, pictures, etc for all tasks which is very useful. Before TickTick, I used Toodeldo. It was okay, but TickTick is just leaps and bounds better than Toodeldo. If you want and need organization in your life, TickTick is the application for you!
