Mobile App Development
Cross-platform mobile apps built to feel native, work reliably, and last.
We build React Native apps for iOS and Android: consumer apps on the App Store and Google Play, and enterprise staff apps deployed through MDM. One codebase, two platforms, no compromises on quality, usability, or security.
You get full source code ownership, platform-idiomatic UX, accessibility built in, and a team that has shipped real apps through the App Store review process more than once. We delivered the member mobile app for Third Space, London's leading luxury gym collection, as part of their Atlas platform rebuild.
From App Store to enterprise MDM
Consumer apps for your customers and staff apps for your teams. We cover both, using React Native as the foundation with native depth where each platform demands it.
Consumer & App Store apps
Customer-facing iOS and Android apps distributed through the App Store and Google Play. We handle the full lifecycle: UX, build, payment integrations, push notifications, in-app purchases, and the App Store review process.
Enterprise & MDM staff apps
Internal tooling for frontline and field teams, distributed via Microsoft Intune, Apple Business Manager, or Google managed devices. Offline-first where needed, kiosk mode where appropriate, and designed for the constraints of managed devices.
React Native with native depth
One codebase, two platforms, but never a lowest-common-denominator compromise. We use React Native with native modules where the platform demands it, Expo APIs for rapid capability access, and platform-specific UI conventions so iOS feels like iOS and Android feels like Android.
Mobile backend integration
Mobile apps are only as good as the systems behind them. We build apps alongside the APIs and backends they need, or integrate with your existing systems. See our mobile app backends service for the full picture.
What makes the difference in mobile delivery
Mobile apps fail in predictable ways: poor UX, accessibility gaps, security vulnerabilities, and App Store rejections. Here is how we address each of them.
Cross-platform without compromise
React Native gives you a shared codebase across iOS and Android, but that doesn't mean a watered-down experience. We use native modules, platform-specific components, and Expo APIs to deliver apps that feel genuinely native on each platform, not a web view dressed up.
Usability and UX discipline
Mobile UX is unforgiving. We follow Apple's Human Interface Guidelines and Material Design conventions, use gesture-driven interactions, and design for the constraints of small screens, variable connectivity, and distracted users. We carry out usability testing before release, not after.
Accessibility built in
We support iOS VoiceOver and Android TalkBack, implement WCAG 2.2 AA for consumer-facing apps, and use platform accessibility APIs throughout. For public-sector and regulated clients, accessibility isn't optional, and retrofitting it is significantly more expensive than building it in from the start.
Security by default
We follow the OWASP Mobile Application Security standard: certificate pinning, secure storage with iOS Keychain and Android Keystore, data minimisation, obfuscation, and jailbreak/root detection where the use case demands it. Security is considered at architecture stage, not bolted on at the end.
App Store & MDM experience
Publishing to the App Store and Google Play involves review processes, metadata requirements, and release management that traps teams who haven't done it before. For enterprise apps, MDM distribution via Intune and Apple Business Manager has its own complexity. We've done both, many times.
You own the code
No proprietary wrappers, no lock-in, no ongoing dependency on us to make changes. You receive full source code ownership, documented architecture, and a codebase that any competent React Native team can pick up and extend.
Our mobile delivery process
From discovery and UX scoping through to App Store submission and ongoing support. A structured process that keeps you in control at every stage.
Discovery and UX scoping
We work with your team to understand your users, use cases, and constraints. For consumer apps, that means user research, journey mapping, and design exploration. For enterprise apps, it means understanding device management policies, offline requirements, and the workflows the app needs to support.
We define the scope, agree the architecture, and confirm the delivery plan before a line of code is written.
React Native build in agile sprints
We build in two-week sprints with regular demos and a working app in your hands from the first sprint. You have full visibility of progress, a shared backlog, and direct access to the team throughout.
Platform-specific testing happens in parallel with development. We test on real devices across iOS and Android versions, not just simulators.
App Store submission or MDM deployment
For consumer apps, we manage the full App Store and Google Play submission process: screenshots, metadata, privacy labels, review communication, and staged rollouts. We know what causes rejections and how to address them.
For enterprise apps, we handle distribution through Microsoft Intune, Apple Business Manager, or Google managed configurations (including device enrolment, app configuration policies, and update management).
Launch and ongoing support
After launch, we provide 30 days of free post-launch support. You receive full access to source code, documentation, and App Store credentials. For teams that want ongoing support, our managed application support service covers monitoring, OTA updates, security patching, and store version management.
Third Space: mobile app on Azure
We rebuilt Third Space's digital ecosystem on Azure, from member management and instructor tools to a new member mobile app, delivering 99.99% uptime on a platform that had previously struggled with demand.

Why React Native instead of native Swift or Kotlin?
React Native lets us build for iOS and Android from one codebase, which reduces cost and keeps both platforms in sync. For most business applications (including complex, data-heavy, or offline-capable apps), React Native delivers native performance and native feel.
There are cases where fully native development is the right call: highly performance-sensitive apps, apps that push platform capabilities at the edge, or teams with existing native codebases they want to extend. We'll tell you honestly if that applies to your project.
Can you publish to both the App Store and Google Play?
Yes. We handle the full submission process for both platforms: app metadata, screenshots, privacy declarations, review submissions, and release management. App Store and Google Play have different review processes, timelines, and requirements. We manage all of it and handle any rejections that come back.
How are enterprise apps distributed without going through the App Store?
Enterprise apps can be distributed through Microsoft Intune (for organisations using Microsoft Endpoint Manager), Apple Business Manager with managed app distribution, or Google's managed Google Play. Each approach requires your organisation to have the appropriate MDM enrolment in place. We work with your IT team to configure the distribution correctly and manage app updates through the same MDM channel.
What about push notifications, background sync, and offline support?
All standard capabilities we build into apps where required. Push notifications are delivered via APNs (iOS) and FCM (Android), using React Native's notification libraries for rich notification handling. For production-grade delivery infrastructure, custom interactive notification actions, and HubSpot-triggered campaigns, see our mobile push notifications service. Background sync and offline-first architecture require more up-front design decisions. We address these in the discovery phase so they're built in from the start, not retrofitted later.
Do you handle App Store review rejections?
Yes. App Store rejections are a normal part of the process, particularly for apps with subscription billing, user-generated content, or privacy-sensitive features. We understand the review guidelines, anticipate likely rejection points during development, and manage the response process if a rejection comes back. Most rejections are resolved within a few days.
How much does mobile app development cost?
It depends on the scope and complexity of the app. A focused internal tool might be deliverable in six to eight weeks. A full-featured consumer app with backend integration, payments, and App Store submission will take longer.
