One of the few truly must-have apps out there at the moment just got a pretty significant security update today. Known as Pushbullet, this app essentially unifies all of your devices so that you can instantly share files and messages between them and even use your computer to see and respond to texts that were sent to your smartphone. It’s definitely worth checking out if you haven’t done so already, especially now that the developers have added support for end-to-end encryption for many of the app’s communications.
