thank you Claude31, appreciate the response. when I said website I should have been clearer and say 'PWA' - it is a 'note app' using web technology. we would plan to package this in a cordova type packaging. regarding your first point let me please double down on that response. If I enabled a 'XX-day Trial' am I right in thinking that it could only get 'unlocked' with an app store IAP purchase? that would seem to be the idea from apple, right? If I did not enable a trial but configured the trial method myself once they sign into my app, is that allowed in the apple rules? or is a developer not allowed to do a trial inside their code which stops the app after yy days. said another way, must an app be providing minimum functionality all the time or could it be only for a certain yy days that is managed by web app not an IAP trial item. thank you !
