I will develop an ios and android react native mobile app
Gary A
About this gig
Need a working iOS and Android app from one codebase? I build focused React Native apps with clear screens, responsive UI and maintainable source code.
Starter: up to 3 screens with navigation and splash screen. Business MVP: up to 7 screens with authentication and one agreed backend or database. Advanced: up to 12 screens with authentication, backend and agreed API or payment features.
Each package includes iOS and Android builds, testing and source code. App store submission is included where selected; you provide active developer accounts and store assets. Third-party subscriptions, hosting and store fees are separate.
Send your feature list, screen sketches, branding and API details before ordering. I will confirm scope and recommend the right package. Complex flows, multiple user roles, AI or custom backend work may need a custom offer.

FAQ
Do you build both iOS and Android apps?
Yes. I build cross-platform mobile apps that can run on both iOS and Android using React Native and related tools.
Can you build my app from just an idea?
Yes. If you have an idea but no finished design or technical plan, I can help structure the app, define the screens and features, and recommend the right package before development begins.
Can you add login, databases, subscriptions, or payments?
Yes. I can integrate user authentication, databases, APIs, subscriptions, in-app purchases, and other backend features depending on your project requirements.
Will you help publish the app to the Apple App Store and Google Play?
Yes. Store submission support is available depending on the package or as an additional service. You will need active Apple Developer and Google Play developer accounts for final publication.
What do you need from me before starting?
Please provide your app idea, required features, preferred design style, examples of similar apps you like, branding assets if available, and any existing backend or API information. For larger projects, message me before ordering so I can confirm scope and pricing.
