The Emu app is an incredible context-aware app that can be fully integrated with other services on your phone, helping create a seamless phone experience. The app is much needed seeing as how apps and services on your phone are walled off and work completely independent of one another.
For example, if you're texting somebody and making plans to meet at a pub, the Emu app will display a map showing you how to get there without you having to exit the text messaging service and open a map app. Emu can also show you Yelp reviews of the establishment as well as other pertinent information.
The app can tell when you're talking about a potential action, and will help make it easier for you to carry out that task without having to switch been apps and exchange tons of text messages.
