Aerofoil

If you've ever worked on a laptop or are a regular laptop user, you know what a pain it is to run out of battery and not have a charger nearby. To keep your laptop alive, you might scramble to turn off certain features, trying to save energy by making it last as long as possible. With Aerofoil, you no longer have to worry about this. Aerofoil automatically deactivates the tools that you're no longer using and the tools that are needlessly wasting energy like Bluetooth, WiFi (if you're not connected to the Internet), the Aero interface, or sound. Thanks to Aerofoil, you can create some extra minutes of battery life by automizing the task of turning off the applications you're no longer using, all before you run out of precious battery life.
