MacroDroid is a task automation and configuration app that focuses heavily on usability with a simple, attractive UI and logical step by step process.

==========
A few examples of what MacroDroid can automate:
==========

Turn on the Wifi connection when you launch a particular app (and off again when closed).
Auto respond to a specific incoming SMS by sending your current location.
Toggle the power button to tell you the time (without taking out of your pocket).
Use NFC tags to configure the device (turn on bluetooth, set volume etc).
