Gas Delivery App for iOS/Android

I have a full set of annotated screenshots that outline every screen of a gas-refill ordering and delivery app. I now need those designs turned into a working mobile application that runs smoothly on both iOS and Android devices.

The essentials are straightforward: customers must be able to place a refill order, track its status in real-time, and manage their personal profile (address book, past orders, basic settings). Payment integration is not required at this stage, so you can focus on a clean ordering flow and reliable tracking logic.

I’m open to either native development or a cross-platform framework such as Flutter or React Native—as long as the finished build passes store review on both platforms and mirrors the UI in my screenshots pixel-for-pixel.
Business Purpose

The app enables households and businesses to order LPG gas cylinders or refills online and have them delivered to their location, similar to how Uber Eats or Mr D delivers food.

Deliverables
• Compiled iOS and Android app builds ready for TestFlight/Play Store internal testing
• Complete, well-commented source code
• Brief setup/read-me so I can run the project locally and submit future store builds myself

Once the above items are confirmed working on actual devices, the project is considered complete.
