Tasks by BlackBerry

Like all of the other Blackberry applications, Tasks can be used completely free for 30 days, after which it will display ads. If you want to keep using it without ads you’ll have to subscribe to BlackBerry Hub+.
As the name of the app suggests, this is a complete solution if you need to keep track of your assignments and if you want to get important reminders for upcoming deadlines and other issues. It might not seem like much, but if you have a lot of tasks that need to be tracked, this is a great app that does just that.
Or course, it comes with an automatic setup for various email services including Windows Live Hotmail, Microsoft Outlook and Microsoft Exchange ActiveSync.
