I've been dedicated to this product for years and provide weekly updates, daily support and video tutorials. I can't do that for free/cheap hence the price. If I charged less, it simply wouldn't be sustainable for me to provide the current level of service and maintenance.

Also, paying a developer to build the same features and invest the time that I have is going to cost a heck of a lot more than $995. It's not just the development hours either, Gravity has been battle tested in over 300+ commercial products and iterated on hundreds of times to incorporate the feedback from those deployments in the field.
