They are similar to the ones that comes with Honeycomb and ICS, but available for Froyo and Gingerbread, and offer more options.

Unlike some of the other Gmail widgets on here, this app works with all the latest versions of Gmail and Android.

Please note:
- When you perform actions on your new mail, these may not be reflected immediately. The purpose of these widgets is to notify you of new messages as soon as they arrive.
- This app will not show up in your launcher. Add widgets by holding down on an empty spot of your home screen.
- It may take up to 1 minute for the widget to refresh the first time and after a reboot. During this time it may not look like anything is happening!
- Do not attempt to move to the SD card, as this will prevent it from working
