Any would you not want to support someone who implanted this? You probably squander more than $20 on meaningless nonsense frequently, why not support him a bit?

		Because at $20 it’s cost prohibitive to a lot of non-professionals who may want to go out exploring and potentially find new discoveries. The app is also a 7 years old

"A contribution is mandatory before I will send the plugin. It may take me a few days to respond, have patience. Please note that the plugin is not an app. It has much more functionality than is possible in an app on a smartphone."

"The DStretch [mobile] app is a lightweight version of DStretch intended to give users the ability to enhance rock art in the field. It is not a substitute for the DStretch plugin which has much more functionality."
