Let me introduce you to Producteev, the latest task manager to hit Android with its official release today. This task manager is a bit different from the other ones in that you can find it on almost any device that you own. Got a Windows machine? They have an app. Their app is also in the App Store for iPhone and the Mac App Store as well. With all these different platforms, the big push is tasks in the cloud that you can add to one place and have them appear in another. The app is a little more diverse in allowing you to create different workspaces for different types of tasks and even lets you sync with other people, allowing one person to assign a task to a group of people so this could be used in an office or work setting very easily.
Installation of the Mac app was easy and signing up is a breeze. As soon as I figure out how to sync this with my Google Calendar (a feature that it says it does) I am going to take a serious look at this. I have needed an app to remind me to take the trash out for a while now. Head on over to the Android Market and see if it will help yourself.
