Connect and organise apps with IFTTT (If This Then That). It's simple programming made easy with what IFTTT calls recipes, where an action triggers another action. For example, if tomorrow's temperature is more than 30 degrees, a text will be sent to you or, if you have taken a photo using Instagram, it will automatically be added to Dropbox (or Flickr, etc). The app is easy to navigate, with options to look at recipes others have used. IFTTT recently added trigger actions based on location. For example, if you're near your workplace, a text is automatically sent to a colleague.
