Google Reader Notifier is a small program for Windows that periodically checks your Google Reader account and notifies you whenever there are new contents to read.
It’s a simple, no-frills program that does exactly what it was made to do – nothing more, nothing less. You can choose how often the notifier will check for new updates. You can also manually check for updates from the tray icon menu.
If you have your feed subscriptions organized into folders, the program will display the list of folders and then you can select only those folders you wish to check updates for.
Notifications are displayed in either a pop-up box or in mouse-over tooltips or both according to your preferences. There are audio notifications available tool. Google Reader Notifier also supports the Snarl notification system.
