Cross-Platform Mobile App Development

Your users are on their phones. Build something worth downloading — and worth keeping.

Most mobile apps fail not because they lack features but because they feel unfinished: slow transitions, janky scrolling, notification flows that break, offline behaviour that loses data. We build cross-platform applications that pass for native — because they are compiled to native code. From a consumer product to an enterprise field tool to a companion app for your web platform, we design mobile experiences that users actually come back to.

WHO THIS IS FOR

Built for teams that need results, not experiments.

Consumer Product Startups
Building an app for end users — marketplaces, fitness trackers, social tools, on-demand services — that needs to look and feel premium to earn retention.
Enterprises with Field Teams
Needing an offline-capable mobile tool for teams in the field — inspectors, delivery drivers, sales reps, maintenance crews — that syncs reliably when connectivity returns.
SaaS Companies
With an existing web product that users want on mobile — a companion app that mirrors core features, sends push notifications, and keeps users engaged between sessions.
Healthcare & Logistics
Requiring mobile apps with strict data security, compliance-aware storage, and reliable performance in low-connectivity environments.
HOW IT WORKS

From first call to production in clear steps.

01
Platform & Tech Stack Decision
We start by helping you choose the right framework for your specific app. React Native is generally better for apps with complex JS integrations or existing web codebases. Flutter is better for pixel-perfect custom UI and demanding animation requirements. We present the trade-offs honestly, including long-term maintenance implications, before any code is written.
02
UX Design & Prototyping
We design in mobile-first Figma — respecting iOS Human Interface Guidelines and Material Design 3 patterns — and produce a clickable prototype for the core flows. We test navigation patterns, gesture interactions, and empty/loading/error states at design time, not during development.
03
Core Feature Development
We build the app feature by feature with weekly testable builds distributed via TestFlight (iOS) and Google Play Internal Testing (Android). You can install and test on real devices throughout development rather than waiting for a final demo.
04
Device Testing & Performance Profiling
We test on a matrix of real devices — iPhone SE through iPhone 16 Pro, mid-range Android — covering OS versions from two major releases back. We profile frame rates, memory usage, battery impact, and cold-start time. We fix crashes, jank, and memory leaks before submission.
05
Store Submission & Post-Launch
We handle the App Store and Play Store submission process end to end — screenshots, metadata, privacy policy, age rating, review responses. We set up Crashlytics for real-time crash monitoring and analytics for funnel visibility. We remain available for the two-week post-launch period to push hotfixes via OTA.
IN DEPTH

The details that separate good from great.

React Native vs Flutter: a real comparison for decision-makers

React Native renders using the native platform's own UI components — a React Native button on iOS looks and behaves exactly like a native UIButton, because it is one. This means the app feels native by default but also means platform-specific bugs appear, and advanced custom UI requires native modules. Flutter, by contrast, renders every pixel itself using its own Skia-based engine. This gives you perfect visual consistency across platforms and makes complex custom animations significantly easier to build, but means the app carries a slightly larger binary and UI doesn't automatically adapt to system-level accessibility changes. For most business applications — dashboards, forms, lists, maps — React Native is faster to build and easier to maintain if your team knows JavaScript. For consumer apps where the UI is a differentiator and you want complete visual control, Flutter often wins.

Building offline-first: why connectivity assumptions will cost you

Any app used in the real world — outside a developer's wifi — needs to handle unreliable connectivity gracefully. This is especially true for field operations, logistics, and healthcare tools. Offline-first architecture means the app reads and writes to a local database first, and syncs to the server opportunistically when connectivity is available. Conflict resolution — what happens when two offline users modify the same record — must be designed explicitly. We use local SQLite with Drizzle ORM, or Realm for React Native, with a sync layer that implements last-write-wins, three-way merge, or business-rule-based conflict resolution depending on your data model. Apps that do not design for offline from day one end up with data loss bugs that are extremely difficult to fix retroactively.

App Store Optimisation (ASO) from launch day

Getting your app into stores is not the same as getting it discovered. App Store Optimisation — the mobile equivalent of SEO — involves keyword research for your app title and subtitle, a description written to match search intent, screenshot designs that communicate the core value in three seconds, and a review strategy that converts happy users into ratings. We handle all of this as part of the submission process. The difference between a well-optimised and a poorly optimised App Store listing is typically a 2× to 4× difference in organic installs per month at zero additional marketing cost.

FAQ

Questions we get asked before every project.

React Native or Flutter — which do you recommend for my app?
It depends on three things: your team's existing skills, the UI complexity of your app, and your integration requirements. React Native is the right default if your team or future hires are JavaScript-focused, if you share a codebase with a web product, or if you need deep integration with JS ecosystem libraries. Flutter is the right choice if your app has complex custom animations, if visual consistency across iOS and Android is critical, or if you want the best possible performance on mid-range Android devices. We are equally fluent in both — we'll recommend based on your specific situation, not what we happen to prefer.
Can you add a mobile app to our existing web product?
Yes. This is one of our most common engagements. We connect the mobile app to your existing backend APIs, share authentication tokens, and implement a feature set appropriate for mobile — typically a subset of the web product focused on the tasks users want to do on their phone. We do not require any changes to your existing backend unless there are specific API limitations that prevent a good mobile experience.
How long does App Store approval take?
Apple's App Store review typically takes 1 to 2 business days for updates and 2 to 3 days for new app submissions. Rejections — which we work hard to prevent through careful guideline compliance — add another 3 to 7 days for resubmission. Google Play review is typically 1 to 3 days. We factor store review time into all sprint planning and launch timelines, and we use TestFlight and Google Play Internal Testing throughout development so the first submission is rarely the first time anyone has tested the app on a real device.
What does ongoing maintenance look like for a mobile app?
Mobile apps require regular maintenance in a way that web apps do not. iOS and Android release major OS updates annually, and apps that don't update their dependencies and test against new OS versions can break — sometimes silently. App Store and Play Store policies also change periodically and require compliance updates. We offer monthly retainer plans that cover dependency upgrades, OS compatibility testing, crash monitoring, and bug fixes. We also respond to user reviews that report bugs and push OTA fixes for critical issues within 24 hours.
Can you build apps that work offline without an internet connection?
Yes. Offline-first is one of our specific areas of expertise. We implement local database layers (SQLite via Expo SQLite or Drizzle, or Realm for React Native) that cache all data the user has loaded, allow reads and writes while offline, and sync to the server when connectivity returns. We handle conflict resolution explicitly — when two offline writes conflict, the app resolves them by a defined rule rather than losing data silently. This architecture is essential for field operations, logistics, healthcare, and any app used in environments with unreliable connectivity.
