Mobile App Development

Apps your users
open every day —
not just once.

Building a mobile app is easy. Building one people actually come back to is a different discipline entirely. We design and develop iOS and Android apps with the kind of UX obsession that earns five-star reviews and drives retention - not just download numbers.

Every kind of mobile product - built to perform

Mobile apps fail for two reasons: they ship slow and they stop getting used. Our process addresses both - short build cycles to get real user feedback early, and product thinking baked in from the first sprint to make sure what gets built is actually worth opening.

Tell us what you're building

Consumer Apps

High-volume consumer applications where onboarding friction, notification strategy, and in-app engagement directly determine whether your retention curve goes up or flatlines after day three. We have shipped consumer apps across fitness, finance, food, and travel - and we know what the metrics look like when the UX is right.

Enterprise Mobile

Field-force tools, operations apps, and internal platforms built for the people who actually use them eight hours a day. Single sign-on, offline-first data sync, MDM compatibility, and the kind of accessibility compliance that enterprise procurement teams check before they say yes.

Marketplace Apps

Two-sided mobile marketplaces for buyers, sellers, or both - with geolocation matching, real-time availability, in-app payments via Stripe, ratings and trust systems, and the notification architecture that drives transaction completion rates without annoying your users into uninstalling.

HealthTech & Regulated Apps

HIPAA-compliant health apps, care coordination tools, and regulated financial apps that pass app store review first time and satisfy compliance teams on second look. Clinical workflow, wearable integrations, and HL7/FHIR data standards handled properly - not as an afterthought.

AI-Powered Mobile Apps

On-device ML inference, LLM-backed chat interfaces, real-time image processing, and personalisation engines that make the app feel like it knows the user - because it does. We handle the model integration, latency optimisation, and the privacy considerations that come with running AI on personal devices.

iOS, Android, or both - built the right way

We work across every major mobile platform. The choice between native and cross-platform is a business decision, not a technical one - we'll help you make it correctly based on your audience, budget, and roadmap.

Native iOS Development

When performance, platform integration, and App Store presence matter above all else, native Swift development is the right call. Direct access to the full iOS SDK - StoreKit, HealthKit, ARKit, CoreML, Siri Shortcuts, and every capability Apple ships - without the abstraction layer that cross-platform frameworks introduce.

Native Android Development

Kotlin-first Android development for apps that need deep OS integration - work profiles, MDM compatibility, background services, and the hardware diversity of the Android ecosystem handled properly. Tested across device tiers and OS versions, not just on a flagship Pixel.

React Native - One Codebase, Two Stores

The right choice for most product-led teams: a single JavaScript codebase shipping to iOS and Android, with native modules available when you need platform-specific behaviour. We build production React Native apps that feel native - not like web apps in a wrapper - and that your existing JS engineers can maintain.

Flutter for Pixel-perfect Cross-platform

When you need identical UI across iOS and Android - design systems, animation fidelity, and custom graphics that behave the same on every screen - Flutter's rendering engine gives you control that React Native cannot match. Preferred for fintech, healthtech, and design-led consumer apps where pixel-perfect consistency is not optional.

Eight weeks, concept to live app.

A structured process with real deliverables at every checkpoint - not a black box that produces an app at the end.

Timelines vary with complexity. Simple utility apps launch in 6 weeks. AI-powered or regulated apps sit at 12–16 weeks. We scope yours precisely before you commit.

Wks 1–2

Discovery & UX Design

User journey mapping, competitor audit, information architecture, and wireframes - all reviewed and signed off before a single line of code is written. Most app failures are designed in, not coded in.

Core Development Sprint

Auth, core data models, primary user flows, and API integration built and deployed to TestFlight / internal testing. You use the real app - not a prototype - from week three.

Three ways to work with us

Whether you're a founder with an idea or a product team shipping v2, there is a structure that fits where you are.

Design Sprint

2 weeks · Fixed scope

Two weeks to validate your concept - user flows, high-fidelity screens, clickable prototype, and a technical spec ready for development. The fastest way to know if your idea holds up before spending a build budget.

  • Full UX research and audit
  • High-fidelity Figma prototype (all screens)
  • Technical specification document
  • App Store listing draft
  • Build cost estimate
Get Started

Growth Retainer

3–12 months · Post-launch

Ongoing sprint capacity for apps already in production - new features, performance work, A/B testing, and platform updates as iOS and Android evolve. Measured in sprint velocity, not hours.

  • Fortnightly feature sprints
  • Analytics-driven feature prioritisation
  • iOS and Android OS update support
  • Performance and crash monitoring
  • Flexible 3–12 month terms
Get Started

What founders and PMs ask us first

Straight answers on cost, timeline, ownership, and what happens when requirements change mid-build. Anything else - just ask.

Most full app builds land between $30,000 and $90,000 depending on platform (iOS only, Android only, or both), feature complexity, and whether there is a custom backend to build alongside the app. A consumer app with auth, a core feature, payments, and push notifications sits around $45,000–$65,000. We scope every project precisely before you commit - no open-ended hourly billing.
For most product-led apps, React Native or Flutter is the right choice - one codebase, two stores, shipped faster. Go native Swift/Kotlin when you need deep platform integration (ARKit, custom Core ML, Android hardware APIs), maximum performance for graphics-heavy apps, or when your roadmap depends on features Apple and Google ship before third-party frameworks support them. We will tell you which fits your specific case.
Yes, from start to finish. App Store Connect setup, app metadata, screenshots, privacy nutrition labels, App Store review management, and Google Play publishing - all handled by our team. We have a near-100% first-submission pass rate because we know what reviewers look for and build against those requirements from the start.
Both. If you have a backend with documented APIs, we integrate directly. If you are building from scratch, we scope and build the API alongside the app - same sprint cycle, same team. We use Node.js, Python/FastAPI, and Firebase depending on what fits your architecture. Everything is built API-first so the mobile app and any future web app share the same foundation.
No mockups required. Every engagement includes UX and UI design. We run a discovery sprint in week one that produces wireframes, a screen-by-screen design, and a clickable prototype - all reviewed and approved before development begins. If you have existing brand guidelines or a design system, we work within them. If not, we build one.
Everything. Full IP assignment is documented before development starts: source code, design files, App Store credentials, backend infrastructure, and any third-party service accounts we set up on your behalf. We do not use proprietary frameworks that create dependency on us. You walk away with a fully transferable codebase your own team or another agency can maintain.
We work in two-week sprints with defined deliverables. When priorities shift - and they always do - we adjust the next sprint backlog. Changes are handled transparently: you see what moves out to make room for what is coming in, and you decide. Nothing gets added silently. Scope changes are costed openly before they are picked up.

Your app. Built properly. Shipped fast.

Tell us what you are building and we will come back with an honest assessment of scope, timeline, and cost - before you commit to anything. No lengthy pitch process, no spec documents before the first call.
