  Someone needs to vibecode some updated options

    That isn't 20 bucks. Seriously, this is crazy pricing for an app.

      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."
