5 paying customers

I updated my Mac app features and changed the model from a free application to a paid application. Some of the free users who loved the app bought the pro paid version with the newly included features. I am not too sure how I acquired those customers. The app has been on the store for some time now and users have downloaded it over the years. I did. bit of Google Adword PPC but that didn't really help for a Mac app.

To be honest I do need to advertise it more.
