The problem with most mobile development companies
Mobile development is either overpriced, underbuilt, or both.
Two separate codebases
Most mobile development companies build iOS and Android separately — doubling cost, doubling timeline, doubling bugs. You pay for the same app twice.
Agency overhead
£100k+ budgets, months of project management, teams of people who never write a line of code. The mobile app takes forever and costs a fortune.
Fragile outsourced code
Cheap offshore mobile development looks fine in a demo. Then real users arrive and the app crashes, drains battery, and gets one-star reviews.
Wall & Fifth builds mobile apps with one codebase for both platforms using React Native — half the cost, half the time, native performance on both iOS and Android.
What this mobile development company builds
Native mobile apps.
iOS and Android from one codebase.
Every mobile app we build uses React Native with Expo — one codebase that produces native apps for both platforms. Real native performance, not a web wrapper.
iOS app development
Native iPhone and iPad apps submitted to the Apple App Store. Push notifications, camera, GPS, biometric auth, offline storage — all native APIs, all supported.
Android app development
Native Android apps submitted to the Google Play Store. Same codebase as iOS, same features, native performance. One build, both platforms.
Mobile app infrastructure
Authentication, database, API layer, push notification services, analytics, crash reporting. Your mobile app launches with real infrastructure behind it, not a demo server.
App Store submission
We handle the entire submission process for both the Apple App Store and Google Play Store — screenshots, metadata, review compliance, and launch. It is part of the project.
