As minimal as Wunderlist is, it still manages to include a few extras that help make task management a bit easier. For instance, if you sign up for a free Wunderlist account, you can sync all of your Tasks and Lists with the cloud, share Lists, and even add Tasks via e-mail. The app also includes a number of different backgrounds with which to customize your experience (though it would've been nice to be able to upload your own).
When it comes to performance, Wunderlist certainly has some room to grow. I found its automatic syncing to be unpredictable, which made me feel as though I always had to manually sync it. To help, I think developers could include options to set the frequency of syncs.
Another feature I found missing from Wunderlist was the option to sync with Google Tasks and Google Calendar. For some, this lack may be a deal-breaker, so I'm keeping my fingers crossed that Wunderlist's developers will add this capability soon. And if they do, I'd love for them to enable syncing of entire Lists, not just individual Tasks.
With a paid Wunderlist Pro subscription, you can add another level of functionality to Wunderlist, upgrading it from a simple to-do app to more of a task management app. The biggest benefit of the premium status is the ability to assign tasks to other users with whom you have shared a list. There's even a Smart List that aggregates all of the tasks that have been assigned to you. Pro subscribers also get access to eight additional backgrounds, which is not terribly exciting. At the moment, Wunderlist Pro accounts don't come with the option to attach files, but according to the folks at Wunderlist, that function is on its way. With that in mind, paid Pro account status might be a tough sell, considering the few benefits it offers at this point.
Overall, Wunderlist is one of the most beautifully designed task managers I've seen for Android. It's sleek, minimal, and incredibly easy to use.
