iOS Port of Under Bounce — Rebuild from Android (No Source Code)

We have an existing hyper-casual mobile game, Under Bounce, live on the Google Play Store. The Android version was built by a third-party developer and we only have the AAB file — no source code. We need an experienced iOS game developer to reverse-engineer and fully rebuild the game for iOS from scratch, matching all gameplay, UI/UX, and functionality of the Android version.

Scope of Work:

Play through and document the existing Android game (link provided)
Rebuild the full game for iOS — matching mechanics, levels, drag controls, star/level system, and visual design
Integrate iOS-specific SDKs: AdMob or equivalent ad network, Game Center, and In-App Purchases
Submit to the App Store via TestFlight, manage review and launch

Budget: $1,000 USD (fixed)

Timeline: 4–5 weeks from project start

Acceptance Criteria:

iOS build matches Android gameplay, UI, and level progression 1:1
Ads, Game Center, and IAP integrations are live and functional
Game runs smoothly on iPhone and iPad (latest 3 iOS versions)
App passes App Store review and is live on the store
TestFlight build delivered for client review before final submission

Requirements:

Portfolio of published iOS games (App Store links required)
Experience with hyper-casual game development
Ability to work from a reference app with no source code
Strong communication and milestone updates throughout

Note: Bids without App Store portfolio links will not be considered.
