Wunderlist 2

Nice TO-DO list manager app/widget that also lets you access your lists from a browser and stores your data online so you don't lose your TO-DO's when changing your phone. Check out Trello too.

Flash Light Widget

Simple light widget. Just turns your flash led on and off. That's it. And the icon is nice.

Digital Clock Widget

After trying several clock widgets I chose this one beacuse it is simple, displays both the date and the next alarm, and lets you open your favourite alarm program when you tap on it.

Business Calendar

This is my favourite calendar. I especially like its widget and how easy it is to add/edit events and see my different Google calendars (work, personal, etc) in custom colors.
