The challenge
A polished iPhone interface is only one part of shipping a serious iOS product.
Product experience
Mobile flows need to work with short sessions, touch interaction and limited screen space — not simply compress a desktop product.
Production engineering
Accounts, APIs, data, notifications, permissions and integrations all have to work reliably behind the interface.
App Store delivery
The product is not finished until the production build is prepared, tested and ready for Apple's release process.
Production iOS development
From product definition to App Store delivery.
Wall & Fifth handles the product, design and engineering layers together. That means the application experience, architecture, backend requirements and release plan are shaped as one product rather than handed between separate suppliers.
We build production software rather than app-shaped prototypes: real accounts, real data, real integrations and a codebase designed to continue beyond launch.
iOS capability
The application layer and everything behind it.
iPhone applications
Custom product experiences built specifically for mobile use.
Notifications
Push and product messaging where repeat engagement matters.
Authentication
Accounts, permissions, biometrics and secure user access.
Payments
Payments, subscriptions and transaction flows where required.
APIs & backend
Databases, business logic and external services connected to the app.
App Store
Production build preparation and release support.
Launch
Testing, deployment and production handover.
Android-ready
A React Native foundation that can support Android expansion later.
The architecture
iOS first without locking yourself to iOS forever.
React Native gives us a strong production foundation for an iOS-first launch while keeping much of the core application reusable if Android becomes part of the roadmap.
That can avoid the cost and maintenance burden of building two entirely separate applications before the product genuinely needs them.
The technology should follow the product. Where dedicated native engineering is genuinely required, that decision should be made from the technical requirements rather than habit.
Pricing
Fixed price. Clear iOS scope.
A focused production iPhone application with the essential product flows required for launch.
