The Good: Wunderlist for Windows Phone is attractive, speedy, and offers useful task-management and collaboration features. The Bad: No numeric notification badge makes it hard to check in at a glance, and I'd be hard pressed to recommend a pro subscription. The Bottom Line: Wunderlist for Windows Phone is fast, free, task-management app that works anywhere you do, and couples cross-platform support with simple collaboration tools. \tThe task-management and collaborative list-making tool Wunderlist has officially made the jump to after spending a bit of time in beta. That's great news: with the move to Microsoft's smartphone platform, Wunderlist users can now manage their tasks on just about anything with a display. \tYou'll find plenty of to-do list apps on the Windows Phone store, but Wunderlist is a bit more than your average list-maker. After a brief beta period bugs were ironed out and crucial features like support for live tiles were tucked in, and the app is now one of the best tools Windows Phone users have to get things done.A list of lists \tWunderlist for Windows Phone looks slightly different than its iOS and , but that's mostly to stay in line with Windows Phone 8 aesthetics. The features are otherwise rather identical -- I suppose it helps that Wunderlist is fairly simple, as far productivity tools go. There's a lists of lists, your profile image, and a background -- you can use a solid color, or choose from a handful of themes. It's a simple, functional design that works rather well. \tBeing free and platform-agnostic is a powerful combination, especially for a tool that only really shines if you can access it anywhere: on the Web, as a desktop application on the Mac, and for iOS and Android. When you first fire up the app, you'll see three fields for Today, Week, and Inbox. Those first two are "Smart Lists" that automatically appear and filter any tasks you've created with a due date. Inbox serves as a sort of catch-all for your tasks: dump everything you need to get done in there. Stuffing everything onto a single list isn't too useful: tap on the large "plus" sign sitting at the bottom of the app's main screen and to create new ones. \t \tThings can get a little more complex. You can assign a number of subtasks to every task, should you need to break a simple task up into a more complex project. Due dates can be accompanied by reminders, which will appear on your Windows Phone's notification center. If you remember something and can't be bothered to log in to Wunderlist (or check the app), you can even email tasks to your Wunderlist inbox. \tYou can also attach files to individual tasks, though you're limited to 5MB with a free account. A Pro account will set you back $5 a month or $50 a year, but it eases restrictions of file sizes, list collaborators, and more. I don't personally see a need to sign up, but your mileage may vary -- especially if you've got a team of interested collaborators. \tIt's important to note that Wunderlist pales in comparison to more robust task managers, which can integrate with your calendars and offer powerful filtering settings to give you a quick idea of tasks that need to be done at particular times or locations. There's also no option to set location reminders, a feature that's available in simple to-do tools like and Apple's Reminders app, and even in Windows Phone's .
