Tasker is a glorious application if you have the patience to learn how to use the app. What it does is allow users to create custom made commands and then use them in various places. There are many apps out there that have Tasker support and you can even use Tasker to create very complex commands for NFC tags. It’s difficult to truly explain what this app can do because it can do so many things. Between the apps supported, plugins you an add, and the sheer volume of stuff that you can do, there aren’t many apps out there as useful as this one. IFTTT is another excellent automation app. In some cases, it may even be better than Tasker thanks to its simplicity and wide range of uses.

Mood Messenger is one of the youngest apps on our list. It doesn’t have a million and a half features, but that’s one of the nice things about it. Mood Messenger keeps things simple while still offering the key features you’ll want. Mood Messenger users can also send messages to each other without using SMS. The app is completely free with no in-app purchases. Droid App
