I need a solid attribution setup for my existing iOS and Android applications so I can see exactly where every install originates and what users do after they open the app. Both platforms matter equally to me, and I want three concrete insights from day one: the original referral source, key in-app behaviors after the first launch, and the conversion rates that follow those behaviors. You’ll help me decide on the best SDK or service—whether that’s Firebase Dynamic Links, Branch, AppsFlyer, Adjust or another option—then wire it into both codebases so the data flows to a single dashboard. The job isn’t done until I can: • attribute each install to its campaign, link or influencer • watch early user actions (signup, purchase, share, etc.) inside the chosen analytics tool • view conversion funnels that prove which referrals perform best My repositories are in Git and both apps are live in their stores, so please be comfortable working around production releases, privacy-safe tracking (iOS ATT compliance included), and writing clear implementation notes for my team. If you’ve built similar cross-platform tracking before, I’d love to see it.
