Wunderlist has updated their beta Windows Phone app.
The app lets you make lists, set due dates for the items, subtasks and generally project manage. Most importantly the app lets you share and synchronize lists between devices and users.
The new update lets you pin live tiles to start screen and also fixes some bugs, including a web socket issue.
Find the real time syncing app in the Windows Phone Store here.
For those unfamiliar, see a video explaining the service after the break.
