If an app can't appear in any app store, rethink the digital marketing mix around discoverability, trust, and direct distribution. Shift budget from store-focused ads to web SEO, deep content development so users install from the browser. Use paid social and creator partnerships to drive demos and downloads, and invest in email and SMS for retention and updates. Replace in-store visuals with rich preview pages, video walkthroughs, and clear security cues to build trust. Track acquisition via UTM-tagged links and custom landing funnels instead of store analytics.
