I posted a question about purchase on their forum and the developer seems supportive too.

In general VST and AU plugins needs to be used in a DAW. Not sure this app has any use other then testing VST or AU plugins.

Many people -myself included- have used Apple's AU Lab, which used to be part of the Developer Tools. Sometimes using a lightweight host is a better alternative to launching a DAW.
