Great app IF used in conjunction with web or iPad versions. – DropTask: Visual To-Do List Review

The web version of Droptask is my favorite task organizer. I've been using it for several months, and it has outlasted most other to-do organizers I've used. I also use the iPhone & iPad versions. The iPad screen is large enough to make use of Droptask's chief virtue--it puts ALL your tasks on the screen, organized hierarchically. You can see them all in one glance. The iPhone version simply can't do that. It doesn't stand alone. But used in conjunction with the web & iPad versions, it's powerful & flexible. Just don't plan on using the iPhone app by itself.
