Just pushed a NostrGram update so the Zappers list is available on mobile. Also, the build number is in the URL now because that prevents browsers from caching the index page. This was sometimes an issue on mobile, particularly on the Android app.

Sir, every new update resets the settings to default. Is that correct?
No it doesn't. Your settings are saved unless you logout and then back in. In a future update (coming soon) they will be saved across logins also. And when I say your "settings", I just mean your NostrGram specific settings. Everything written to the relays is loaded from the relays each time you login.
