Rebuild Source for Mobile App

I released a consumer-facing app on both iOS and Android some time ago but, unfortunately, the original source code is no longer available. All I can provide today is the signed iOS IPA. I need someone who can either decompile that binary to recover as much logic /UI as possible or, if that proves impractical, rewrite the application so that it behaves exactly the same on both platforms.
Core behaviour to replicate
• Secure user authentication (current flow uses email + password).
• Push notifications that mirror the existing timing and payload structure.
What I will supply
– The live IPA, screenshots of every screen, and a short video walkthrough so you can observe each interaction path.
– Existing branding assets, copy and any server-side API documentation still on hand.
What I expect back
1. Readable, well-commented source projects for iOS (Swift or Objective-C) and Android (Kotlin or Java; a React Native or Flutter build is fine if it speeds things up while keeping parity).
2. New build artifacts ready for TestFlight and Google Play internal testing.
3. A brief setup guide covering dependencies, signing, and how to trigger push notifications from our back-end.
4. Confirmation that authentication and push alerts work on at least one physical device per platform.
I’m happy to walk through the current app on a call and answer technical questions quickly so you can gauge the effort involved. If you have proven experience salvaging or recreating legacy apps, let’s set up a chat and get this moving.
