Imagine you're working at your desk, and you feel your phone buzz in your pocket. It's not exactly onerous to pull it out, but doing so can break your workflow. Desktop Notifications solves this all-too-common minor annoyance by displaying your device's notifications on your main screen, with practically no setup.
Once you grab the free app from Google Play, it will direct you to install a browser extension on either Firefox or Chrome. From here, you add your Android device's unique identifier from the Desktop Notifications app. Now, any notifications on your phone will pop up in the corner of your screen, assuming your browser is running. You can customise the app to choose to choose which apps display notifications.
The idea is similar to previously-mentioned Android Notifier, but it's a lot easier to set up since everything runs in the browser. It also doesn't require your phone and computer to be on the same network, or paired via Bluetooth, which can be handy at work if your phone can't access the main network.
