Service 02 ยท Mobile Product Engineering
We design and build mobile applications, help you choose the right approach for your product, and deliver the backend, APIs and release process the app depends on.
Business problem
The challenge
How to build a mobile app is a business decision. An iOS app, a Flutter app and a React Native app carry different costs, timelines and long-term trade-offs, and the wrong choice is expensive to reverse. Many projects also underestimate the backend, the store release process and the maintenance that follow launch.
Our approach
We start from your users, your budget and the features you need, then recommend an approach and explain the trade-offs in plain language. We build the app together with its backend and administration tools, and we support publishing and updates.
Agree who the app is for, which platforms matter, and which features need device capabilities.
Select iOS, Flutter or React Native, then prototype the core journey so it can be tested with real users.
Develop the app and its backend in increments, testing on real devices and operating-system versions.
Publish to the stores, monitor how the app behaves and keep it current as operating systems change.
Capabilities
Applications for iPhone and iPad designed around Apple platform conventions.
One codebase for iOS and Android with a consistent, custom interface.
One codebase for iOS and Android written in JavaScript or TypeScript, sharing skills and logic with React web products.
Secure APIs, authentication, notifications and data storage behind the app.
Interfaces designed for touch, small screens and real usage conditions.
Camera, location, push notifications and offline use where the product needs them.
Preparing builds, listings and submissions for the App Store and Google Play, and handling review feedback.
Device testing, operating-system updates, bug fixes and new features after launch.
Choosing an approach
General characteristics of each approach, not a ranking. The right choice depends on your product, your users and your team.
| Consideration | iOS | Flutter | React Native |
|---|---|---|---|
| Platforms | iPhone and iPad | iOS and Android from one codebase | iOS and Android from one codebase |
| Language | Apple platform languages and tools | Dart | JavaScript or TypeScript |
| Interface | Apple standard components, with new platform features available first | A custom, consistent interface drawn by the framework | Uses each platform's native interface components |
| A good fit when | The product is iOS-first or needs deep Apple platform features | You want a strongly branded interface on both platforms with one team | You have a React web product or a JavaScript team and want to share skills and logic |
Technology
Only technologies our team uses hands-on are listed.
Architecture considerations
A mobile app is one part of a larger system. The app, its backend and its release process are designed together.
Business rules live in the backend where they can be updated for every user at once, and the app stays focused on experience.
Where the product needs it, local storage and synchronization let the app work on unreliable connections.
With Flutter or React Native, one codebase serves both platforms. Platform-specific code is isolated behind clear boundaries.
Notifications, scheduled tasks and background processing are designed to respect battery, permissions and platform limits.
Staged builds, feature flags and versioned APIs let older app versions keep working while new ones roll out.
Security considerations
These are the practices we plan into the work. They are not certifications.
Tokens and sensitive values use the platform keychain or keystore, not plain local storage.
The app communicates only over encrypted connections and validates server responses.
Authentication uses tokens that expire and can be revoked, so a lost device can be cut off.
The app requests only the device permissions it genuinely needs and explains why.
Third-party packages are reviewed and kept up to date, since they are a common source of vulnerabilities.
How we work
Every engagement follows the same seven stages, with a checkpoint at each.
Business requirements, users, constraints and objectives.
Technology strategy, system architecture and a delivery roadmap.
UX and UI design with technical specifications.
Engineering and integrations, delivered in tested increments.
QA, security and performance testing before release.
Production deployment with monitoring in place.
Optimization, maintenance and future development.
Relevant industries
POS, QR ordering, inventory, loyalty, franchise management and business analytics.
Digital commerce, inventory, customer engagement and analytics.
Digital platforms, workflow automation, patient-facing systems and data solutions.
Relevant projects
We do not have a published client case study for Mobile Product Engineering yet, and we do not show work we cannot stand behind. Our own products, and the solutions we can build, are listed with their status.
FAQ
It depends on your product. iOS suits an iOS-first product or one that needs deep Apple platform features. Flutter and React Native suit products that must run on both iOS and Android with one team. We recommend an approach after a discovery conversation and explain the reasons.
Yes. Flutter and React Native apps run on both iOS and Android from a single codebase. If you need Android support, we cover it in discovery and plan it into the scope.
We prepare the builds, listings and submissions, and support you through review feedback. We recommend that the developer accounts belong to your company.
Yes. Operating systems change every year, so we can provide ongoing updates, fixes and improvements, with the level of support agreed in advance.
