Using TaskTask, you can manage your to-do list, create tasks, set start/due dates, mark complete, assigning categories, change importance, set and receive reminders, and delete tasks. An Exchange Server or Office 365 account is required to synchronized tasks with Outlook. No additional software is necessary. TaskTask works with Gmail directly, although in a limited fashion. Key Features: - Simple interface, quickly create new tasks and mark tasks completed - Set task attributes, such as category, importance, start/due/complete dates, and notes - Synchronize your task list with your e-mail account (no hidden fees or software to download) - Quickly swipe to complete or delete a task - Easy set up with automatic configuration of your server - Drag-to-order your tasks, see the same order in Outlook - Recurring tasks and reminders - View attachments on your tasks and attach files from other apps How is TaskTask better than Reminders? - See your task list how you prefer: organize by start date, due date, category, importance, or reminder date. - Reorder your tasks just by dragging them around - Full category support, including downloading your list of categories and colors from your Exchange Server. - See tasks in the same order as Outlook's To Do Bar - Task filters: filter out tasks in the future or tasks you don't want to see on your mobile device - Flagged mail items: See the full list of items from your To Do Bar, not just tasks - Quick Task Entry: Type a list of task subjects quickly in one space, and TaskTask automatically creates the set of tasks - Mark tasks as private: Hide tasks from others who have visibility to your task list Note: To synchronize your tasks with Outlook, your email account must be on a compatible Microsoft Exchange Server or Office 365 Business account. Microsoft Exchange Server 2010 and newer versions are supported, although there may be additional factors that prevent TaskTask from working with your server. If you are using Mail.app or Microsoft Outlook 2011 (Macintosh) with your email account in "Exchange" mode, TaskTask is compatible with your server. Because there are specific requirements for your server, please verify with your e-mail administrator that your server meets these requirements before purchasing this app.
