There’s already one ring to rule them all. How about one to-do manager? That’s the idea behind Wunderlist (Free) from 6 Wunderkinder. It’s a Mac App Store Download that allows you to organize your life, and it syncs across all of your devices—PC, iPhone, iPad, Android, and the web. Yes, you read that right: all those platforms and it’s free.
The interface is dead simple: on the right there’s a list of all your projects, to dos, or whatever else you’ve set up. To the left is the main window that displays the tasks for each list. The whole interface is drag and drop, so you can move tasks around in order or even to different lists and check them off when you go. There are even social features so that you can share your lists with friends. Between the simplicity, the syncing, and the price tag, you no longer have a good excuse for forgetting your tasks.
