Badge Checker for Gmail™ is an addon that displays notifications for your unread emails in Gmail. If you use multiple accounts, it will show you all your unread emails on your Android phone. It displays a badge notification with a number showing how many unread emails are there for each account, so you can easily check them.

You can also set the badge number to break down into each unread email in the box below.

Badge Checker for Gmail™ supports multiple accounts, so if you have more than one Gmail account, it will display all unread emails from all your accounts in the icon. It also supports labels and supports multiple mail accounts with just one installation. You can enable or disable it in your account settings.
