From the developer:
AppStorify helps you find all non-App Store apps and check whether they are in App Store. You can use the App Store's upgrade mechanism instead of app's. The App Store apps are reviewed and sandboxed. The tool supports clean install and uninstall from App Store.
You may want to check out more Mac applications, such as BookTracker, Statistics Pro Demo or Reunion, which might be similar to AppStorify.
