Anyone know an Android widget/app that will tell you version number you're running of an app?

I would like a widget that would show me what verison number I am running of a specific app. You can get this info from going into apps and looking at the specific app, but I have a lot of phones and I want to see what version I'm running at a glance on the desktop. E.g. Perk version 2.0 or 3.0
