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.

Nova Launcher Prime

This launcher lets you customize many aspects of your desktop and app drawer. I like the gestures, the app groups and how you can increase the rows and columns of your desktop and resize your widgets.

SwiftKey keyboard

I've tried several keyboards and this one is my favourite. You can type or slide/swipe, it predicts your next word and improves with time by learning from you, and it's not necessary to select the language you want to write in.
