Satisfies a real need

Over the years I have accumulated lots of files in déjà vu format. They have the virtue of being very compact, but it is not easy to find readers capable of handling them. This developer provides a real service by creating an app that not only handles déjà vu files but does it so beautifully. When I first used this app I found a bug. Within an hour of notifying the developer I received a reply, and a couple of weeks later, the app was updated correcting it. The developer clearly loves this app and is determined to make it offer the best user experience possible.
