But most apps and even Zapstore itself are based on apks package installer format. No point coz once Google starts to close the entry and the exit door of the entire apks eco-system....that's it. That's why it's advisable for apps creators to follow the footsteps of the nostr-based ' Keychat ' app creator. Keychat caters for all OS system...either through apps or browser itself ( ios/android/linux ) for phones & ( windows/Mac/Linux ) for pcs. If any of the single authority corporation tries to shut it down...hell we still have Linux.
