Okay, all granted, but now that we agree you keep all your data which is safe, we only need discuss how no other than totally trivial project I think can really be "[stuck] on the app store and [ignored]," not for more than a couple years. Anything with meaningful platform integration would impose the same requirement, not to mention the $100 pa vig and time investment required just to show up at the party. In 2025, for something whose basic concept is obvious and the differentiator is polish, I don't see this as a tremendously reasonable showstopper the way you're treating it, even for a first time dev.
"Assume good faith" and that. Fair to ask, but show the courtesy due an equal at least until it is evident that is unwarranted. This engineer has done work demonstrating they are at least my equal and I am not prepared to treat them otherwise only because I have not seen them do so before. The 32/64 bit and Intel/Arm transitions should be enough warning for anyone and lie well within living memory.
Someone may cavil over "polish," I suppose. I have a 5-quart 'Artisan' Kitchen-Aid stand mixer in lavender, because that nicely sets off my kitchen decor and because I impose light enough duty on that machine to make aesthetics a reasonable figure of merit. This app is not that kind of machine. Who cares what color the cover plates are, when the target audience will never run the machine with them installed anyway?
(And unless there exists a design patent, why worry about a case where, at worst, you already know what market you need your product to fit?)
