Any.Do: Clean, Crisp, and Easy-To-Use Tasks and Reminder App and Chrome Extension

Found a great app that seems to be very easy to use and very clean and simple for organizing your To Do lists.  The app is called Any.Do (and the site is Any.Do.  I've added a screenshot from my own phone of the sleek look of the app.  It works with Android, iPhone, iPad, and Chrome so you use it on your computer as well as your mobile devices.  It's very drag and drop and Siri works great with it on the iPhone. You can also set reminders and bring someone else in on a task.

Give it a look....the best thing is that it's free which is perfect for an educator's budget.
