Hi,loverofmanutd!Try using Wunderlist. Wunderlist's greatest strength is in its flexibility. The Android app is great and richly featured on its own, and gives you access to all of the features you would want from a mobile to-do manager. You can add tasks easily, move them around between categories or star them to mark them as important, change due dates, and even change the view so you can focus specifically on the most important items you have to work on. Plus, all of your tasks and changes are synchronized to your Wunderlist account on the web so you don't have to sync or push your changes to another device. Additionally, you can share to-dos with other users and collaborate on projects. Plus, it doesn't hurt that Wunderlist is available for virtually every platform, with native apps for iOS, Windows, Mac OS, and Linux in addition to Android and a fully-featured webapp.
