Pushbullet is an extremely useful file-sharing app that is designed to take the hassle and stress out of the process of sharing information between devices.
The app essentially allows you to rapidly and easily 'push' files from your computer to your smartphone or tablet at the click of a button. We often find ourselves in situation where we come across an interesting link or file on our smartphones, but would rather open them up on a computer due to the fact that its screen is larger. Now, rather than having to email yourself a link or attachment, you can simply use Pushbullet to transfer the link or file over to your other device.
Pushbullet goes to show how app development is being increasingly influenced by the fact that many people now use multiple devices.
