Google had named its ten best apps of the year. You will find the list at this link (will take you to Google Play). There is one app I think should be on the list, Tasks by Team Tasks.
Ironically, Android does not have a native app for its tasks list which is part of Google Calendar. I use tasks a lot, and when I got an Android the first thing I tried to do was find a great tasks app, which synced with Google Tasks. After over a year of jumping from one app to another, most of which I found too busy, I found Tasks by Team Tasks. It is a well designed app that does not overcomplicate the function of maintaining a task lists and really feels like a native Android app. It brings 100% of the functionality of Google Tasks to your phone with a a nice Holo themed user interface. It even has a option for a tablet optimized interface. I think Google should have placed this on their best ten apps list.
