Manage a number of Google and Gmail accounts using a single app
Syncing with Google is a lot easier thanks to the introduction of applications like this one.
The Google Tasks Organiser takes something that Google already offers but makes it nicer, simpler and easier to use.
The Organiser is customisable and lets you link different Google and Gmail accounts in one place, making them easier to manage. To do lists and tasks can be set to appear and reminders can be set for events, different types of reminders are available for different types of events.
The developers post regular updates to the app meaning that it is regularly improved and tweaked for performance.
It is very easy to use and an excellent complement to the on board Google Mail and Applications packages.
