iOS & Android · React Native · Flutter
Apps that ship to both stores. Built once.
We build iOS and Android apps using React Native or Flutter where a shared codebase makes sense, and native Swift or Kotlin when performance demands it. The backend and the app come from the same team: no handoffs, no integration surprises.
- 30+ apps live on both stores
- Fixed-cost from spec sign-off
- App + backend, same team

Framework
The right mobile app development framework.
We don’t have a preferred framework we push regardless of your needs. We recommend based on your app’s performance requirements, timeline, and budget.
recommended
React Native
JavaScript · TypeScript
Write once, ship to iOS and Android with near-native performance. Huge ecosystem, fast iteration, and easy web skill reuse. Our most-used framework.
Best for
- Business apps & dashboards
- E-commerce & booking platforms
- Social & community platforms
- Apps that need web team involvement
Flutter
Dart · Google
Pixel-perfect UI on both platforms from a single Dart codebase. Excellent for highly custom designs and apps where visual consistency across platforms is critical.
Best for
- Custom-designed UI with animations
- Apps with complex visual interactions
- Fintech & healthcare UIs
- When pixel parity between platforms matters
Native
Swift · Kotlin
Pure Swift for iOS, Kotlin for Android. Maximum performance, full platform API access, smallest footprint. Only recommended when the performance or hardware requirements demand it.
Best for
- Real-time video / AR / camera apps
- Apps with deep OS integration
- High-frequency trading or sensor apps
- When budget allows separate iOS + Android builds

What we build
Six app categories we know well.
Thirty-plus apps across six verticals we’ve solved the hard problems in each category before. You get patterns that work, not experiments on your budget.

What's included
Design to App Store: quoted to scope.
Every app engagement is scoped before build starts, with the quote based on features, integrations, backend needs and store submission requirements.
Full-scope delivery
App development the way it should work.
You talk to the engineer writing your code. The same team that designs the screen builds the component, wires the API, and submits the binary to the store. One point of accountability from spec to live.
UI/UX design in Figma
Wireframes → high-fidelity → dev handoff
Cross-platform build
iOS + Android from a single codebase
Backend / API
WordPress REST, custom Node, or Supabase
Push notifications

Process
From idea to both stores in five stages.
Every app engagement follows the same structured path so you always know where things stand and what comes next.
01
Scope call
Free 30 minutes. We assess whether you need an app, which platform, which framework, and give you a ballpark. No pitch deck — honest answers.
02
Spec & design
Screen-by-screen wireframes, then high-fidelity Figma designs. User flows, edge cases, component library. You approve before any code is written.
03
Build
Weekly staging builds you can install on your device. Shared Linear board. You see and test every screen before we move on. Fixed cost from spec sign-off.
04
QA & testing
Device testing across iOS and Android, performance profiling, accessibility audit, crash monitoring setup, and App Store / Play Store metadata preparation.
05
Ship & support
We handle both store submissions including any review rejections. 30-day bug warranty post-launch. Optional ongoing retainer for updates and new features.
Technical capabilities
The hard problems we've solved before.
Every mobile category has its own set of tricky integrations. Here’s where we have deep, proven experience.
Payments & In-App Purchase
Stripe, Apple Pay, Google Pay, GoCardless Direct Debit, and Apple/Google in-app purchases. Recurring subscriptions with smart retry. Deposit flows for bookings. PCI-compliant tokenisation: card data never touches your server.
Push Notifications
FCM (Firebase Cloud Messaging) for Android and APNs for iOS. Rich notifications with images and action buttons. Deep-link routing from notification tap directly to the relevant screen. Segmented campaigns via your backend or Mailchimp.
Offline-First
AsyncStorage, SQLite via WatermelonDB, and Redux Persist for optimistic UI with background sync. Field workers, charity collectors, and clinic staff use apps in areas with no signal: your app should still work.
Auth & Security
JWT, OAuth2, Apple Sign In, Google Sign In, biometric authentication (Face ID / Touch ID / fingerprint). Secure Enclave storage for tokens. Two-factor via SMS or TOTP authenticator app. Role-based access within the app.
Maps & Location
Google Maps and MapBox integration for salon locators, service area maps, and delivery tracking. Background geolocation for field team apps. Geo-fencing for proximity triggers and location-based push notifications.
Backend Integration
WordPress REST API, custom Node/Express APIs, Supabase, Firebase, and GraphQL. We build the backend alongside the app: no integration bottleneck between two separate teams. Shared Postman collections and auto-generated TypeScript types from your API schema.
Stack
Tools we ship with every day.
The mobile stack is chosen around the product: one codebase when speed matters, native code where the device integration needs it, and a backend that is built alongside the app.
Cross-platform app build.
React Native or Flutter when one maintainable codebase can serve iOS and Android without sacrificing the core customer experience.
Swift
Kotlin
Backend and payment flows.
WordPress REST, custom APIs, Stripe, subscriptions and secure media storage connected by the same team building the app interface.
REST
Release and feedback loop.
Design, sprint planning, CI, crash reporting and analytics are wired in from day one so launches are controlled and improvements are visible.
App delivery layer
Prototype, build, submit and support.
We handle the parts around the code as well: store assets, TestFlight builds, Play Console setup, analytics events and the first post-launch fixes.
Prototype
Figma flows before code.
API contract
Shared schemas and typed responses.
QA devices
Real iOS and Android checks.
Store prep
Listings, review notes and builds.
Analytics
Events that show what users do.
Support
Launch warranty and update path.

FAQ
Questions we get every week.
The timeline depends on the project’s complexity. A typical mobile app takes 10–16 weeks, while larger apps with custom features, integrations, or complex workflows may take longer.
Yes. You’ll need your own Apple Developer and Google Play Developer accounts so you retain full ownership of your app. We help you set them up and manage the entire submission process.
Yes. We develop both the mobile application and the backend API. If you already have an existing backend, we can integrate with it instead.
We handle the review process, respond to store feedback, make any required changes, and resubmit the application until it meets the platform’s requirements.
Yes. We offer ongoing maintenance, feature development, bug fixes, performance improvements, and compatibility updates for new iOS and Android releases.
Absolutely. Once the project is complete, you receive full ownership of the source code, design files, documentation, and app store assets.
Pricing is based on your app’s features, integrations, design requirements, backend functionality, and overall complexity. We provide a tailored quotation after discussing your project.
Yes. We can connect your mobile app to WordPress, WooCommerce, membership systems, CRMs, custom APIs, and other existing business platforms.
Yes. We build cross-platform applications that run on both iOS and Android from a single codebase, reducing development time while maintaining a native user experience.
We build business apps, eCommerce apps, booking systems, charity and donation apps, healthcare solutions, education platforms, membership apps, customer portals, and other custom mobile applications tailored to your business goals.
