Mobile Application Development .
iOS and Android app development in the UK. React Native where it fits, native Swift or Kotlin where performance demands it. Apps users keep.
What's included
Everything you get.
End-to-end mobile development. From design to App Store.
iOS & Android
React Native for cross-platform speed; Swift for iOS, Kotlin for Android when native performance is required.
API & Backend Integration
Seamless connection to your existing backend, third-party APIs, OAuth flows, push notifications and real-time data.
Offline & Sync
SQLite/MMKV local storage, background sync, conflict resolution. Your app works without a signal.
UI/UX Design
Platform-native design patterns for iOS and Android. HIG compliance, Material Design, custom design systems.
App Store Submission
We handle metadata, screenshots, review guidelines and App Store Connect. So launch day is a celebration, not a scramble.
Post-Launch Maintenance
OS version updates, crash monitoring (Sentry/Firebase), feature sprints, and App Store optimisation.
Why clients come to us
Problems we fix.
The problem
You need both iOS and Android but can't afford two separate codebases
Our solution
React Native gives you one codebase for both platforms. With native modules where performance matters most.
The problem
Your app was rejected from the App Store and you don't know why
Our solution
We review your submission against Apple/Google guidelines and fix the issues. Typically within a week.
The problem
Your existing mobile app is slow and users are abandoning it
Our solution
We audit, profile, and optimise. Targeting render performance, network efficiency, and offline resilience.
The problem
Push notifications and deep links behave differently depending on the device
Our solution
We implement and test notification and linking infrastructure properly across iOS and Android, not just the happy path.
How we work
A process you can follow.
Four stages. Each one has a clear output before the next starts.
- 01 Discovery
Understand the brief
We dig into your goals, your users and the platforms that matter before writing a line of code.
- 02 Design
Design the experience
Native-feeling flows and interface, planned and reviewed before build begins.
- 03 Build
Ship to the store
An experienced team builds it — every pull request reviewed, every release tested.
- 04 Run
Support after launch
Monitoring, updates and store maintenance — we don't disappear at go-live.
Common questions
Quick answers.
React Native or native. Which should we choose?
For most business applications, React Native delivers 95% of the native experience at roughly 60% of the cost and timeline. We recommend native Swift/Kotlin for graphics-intensive apps, ARKit/ML features, or Bluetooth/hardware integrations.
How long does a mobile app take to build?
A focused MVP (core features, one platform) typically takes 10–14 weeks. Both platforms in parallel adds 2–4 weeks. App Store review adds 1–2 weeks on top.
Do you submit to both the App Store and Google Play?
Yes. We handle the full submission process. Accounts, metadata, screenshots, age ratings, and review correspondence. For both stores.
What if our app is rejected?
We review the rejection reason, fix the issue, and resubmit. App Store rejections are part of every mobile project. We build review time into our timeline.
