TypeSample doesn't need any installation. It works directly in the Browser as a bookmarklet with a 1-click setup. Once installed, it can identify the font family of any text on the internet by simply hovering over it. Review collected by and hosted on G2.com.

If TypeSample was a native app installed at the OS level instead of the browser, I'd use it in more places where I'd like to know the font in use. In its current form, it can only be used on websites and not other apps. Review collected by and hosted on G2.com.
