Of course nothing against the developer. But going Apple-first may be the problem here. It doesn't fit the Nostr/Bitcoin spirit at all. Heard, they're even in the fiat money lending business now. Then we saw all the problems with their app store that wanted to take a big fee out of every zap.
Bitcoin/Lightning and Nostr devs should avoid these stores (Google Play Store also) and just deliver downloadable packages, just as Primal did in the beginning. Maybe this would trigger an effort to build an own app store for these types of "freedom tools".
Apple had no problem cancelling Macromedia Flash on their systems back then. Time they taste their own medicine.
