Several years ago, probably about 5 or so, I ran across a program that worked on PC and Mac, as well as ported as apps for mobile devices. It gave me the ability to create checklists and tasks that I needed to get done. It also allowed me to share lists with other users. It was a great way to share, at least for me, items I needed student workers or other team members to get done. It also gave me a way to keep track of what items were getting done and which ones were left.
Flash forward to last month, when I read how Sunrise, a calendar app that works with Android devices, incorporated Wunderlist in it. Thought that was pretty cool.
Then I read today where Microsoft has bought them and will probably help grow the product even more.
If you have not tried Wunderlist, I urge you to give it a shot. Clean, functional, easy to learn and use. You could do worse.
