Pressy

In an age where manufacturers try to strip our devices of buttons, Pressy goes against the current by adding one back, and with good reason. Basically a headphone jack with a button on its end, plug Pressy into your Android device (sorry, iOS users, the sandbox is still too small) to create a fully customizable button that recognizes different clicks – short, long, double click, etc – to trigger actions. Possible actions include taking photos instantly, flicking on the flashlight, activating voice recording, WiFi/Bluetooth toggling, shutting down all running apps, and much, much more.
