OK. I understand. I support all developers and I fully agree that when an app/mod needs to be rewritten from 0 to accommodate a new platform it deserves additional payment. But the the new price is 2.5x the previous version, which in my opinion is quite large increase. I don't want to appear to be whining and you have the full rights to price an app in a way that it represents the work you put in to it. I fully respect that, just sharing an opinion.
