At Google I/O last week, Google introduced Heads Up notifications in Android L, which are essentially pop up notifications for applications. No matter which app you are in, at any given time, you can see notifications on your display, which also have the ability to perform actions right from the notification pop up.
Unless you have a Nexus 5 or Nexus 7 running the Android L developer preview, you are probably going to be waiting a very long time until this feature hits your device, but thanks to a developer, Heads Up! brings this functionality to any Android device running Android 4.3+.
Basically, the app takes notifications from your phone, then turns them into pop up messages. As you can see in the picture above, if you receive an email, you can double tap to open up the application, swipe to the right to dismiss it, or even reply and delete the email all from whatever app you are in. To put it simply, it’s a pop up notification bar.
To check it out for yourself, grab it off of Google Play for just $0.99.
