"Linux App Finder's mission is to catalog useful GNU/Linux programs and provide a great resource to discover new apps". The programs are organized in categories to browse the collection. It has an alternatives page to find an equivalent Linux app to replace your Windows or OS X app when you make that switch. The app's page has user submitted screenshots and a research section where links to reviews for that app is provided.
