If you’re interested in using more Chrome apps but not sure where to start, There’s a Web App For That suggests Chrome apps based on your browsing history.
After you install the extension it scans your browsing history and your installed apps, extensions, and themes to suggest Chrome apps you might find useful. After the initial scan it continues to suggest apps by placing a small blue [+] icon in the address bar when you’re visiting websites that have a dedicated Chrome app. If you missed the dedicated Evernote app suggestion in the initial scan, for example, the next time you visit the Evernote web site the icon will appear to remind you an app is available.
There’s a Web App For That is free Google Chrome extension.
