This is such an interesting experience, especially with canceling to what seemed to be a promising kickstarted campaign. I am glad you killed the subscription based model and are now selling it simply as a product.
So many services are competing for your $10-$100/month these days it's ridiculous. Let me own something. Let me pay you one time and be done (hello, Amazon Prime!).
Once I gather my thoughts I'm going to write about the end of the monthly subscription. Personally I think much harder about a $10/month subscription than a $25 "one"-time purchase; I wonder if we've reached an inflection point where most people do, or if most still see it as "only a couple bucks a month"?
