I have a not well thought out idea that there needs to be a Zapstore-like mobile app where it’s your one-stop shop for onboarding to Nostr, secure key storage and profile management, signer, and Nostr App Store. It would be an entry point to all things Nostr but you would need to download micro apps through the app store to access specific functionality.

That’s what will keep away the majority of people not to use nostr because it’s “overcomplicated” and you have to have tons of apps on your phone
To be fair: a signer app isn't mandatory for new users nor for people just trying out different apps around NOSTR.
People use it when they have different tools that they enjoy and want to reuse their account on it.
In fact would argue that NOSTR apps tend to be easiest ones to start using. Identifies are generated immediately and starts using the app right away.
