Does not launch in El Capitan

The app will not launch in El Capitan, so I deleted it, and was about to attempt to re-download it, but the App Store says $11.99. Rather than risk being charged for it, I decided it is not worth my time.

If you are going to sell apps on the App Store, and run a proper software business, you have to dedicate your life to it ... no room for updates every few years. Just the inconvenience of having to remove the app, means it is not worth the customers time.

The Mac OS updates yearly, so, as a developer, if youre not going to keep up with that, please dont sell apps on the app store, thanks.

Too bad, this was a nice app when it was compatible with the Mac OS.
