Not a long time ago, the developers of Whatsapp came up with a solution to this by creating their Web version of the Whatsapp application. This way users are able to chat through their personal computers rather than a simple scan of a QR code.
Of course, this resolved the situation for many of us, but there are still applications out there that send you notifications and require you to check your phone all the time. In this case, an app called Pushbullet comes in handy.
Pushbullet helps you read notifications as well as reply to text messages through your PC instead of constantly picking up your phone. Pretty neat, huh? All you have to do is install the app on your Android device, then authorize it to have access to your messages and finally, sign in with the same Google account you signed onto your device at their control panel through your PC.
