MacroDroid
MacroDroid is a task automation and configuration app that focuses heavily on usability with a simple UI and logical step by step process.
A few examples of what MacroDroid can automate: • Turn on Wifi or Data connection when you launch a particular app (and off again when closed). • Respond to an incoming SMS by sending your current location. • Toggle the power button to tell you the time (e.g. when its in your pocket). • Use NFC tags to configure the device (turn on bluetooth, set volume etc).
