Cross-Platform Mobile App Development

One codebase across iOS and Android with Flutter or React Native, for products where native-per-platform is not worth the duplicated cost.

Cross-platform development is the right default for most mobile products: one codebase targeting both iOS and Android, which means one team, one release cycle, and roughly half the ongoing maintenance of building and keeping two native codebases in sync. It stops being the right default when an app needs deep platform-specific capability that a cross-platform framework cannot expose cleanly, which is when native development, covered on the iOS and Android pages, is the better call.

This page covers Flutter and React Native development specifically. We will tell you honestly which approach fits your product before proposing either.

What We Offer

Flutter development

Single-codebase apps with native-compiled performance, well suited to products where UI consistency across platforms matters as much as native feel.

React Native development

Cross-platform apps sharing code with a React-based web product where one exists, useful when a team already has React expertise in-house.

Offline-first architecture

Local data persistence and sync logic for field or connectivity-constrained environments, so the app remains usable when the network is not.

Push notifications and background sync

Notification infrastructure via Firebase and background data sync that behaves correctly across both platforms’ different lifecycle rules.

How We Help

The decision between cross-platform and native is a real engineering trade-off, and we make it honestly rather than defaulting to whichever framework we most recently used. Cross-platform wins when time-to-market and one shared codebase outweigh needing the newest platform-specific APIs on day one.

A recurring problem we solve within cross-platform apps specifically is connectivity: field operations, wallet apps used in low-signal areas, or telemedicine access in regions with unreliable networks all need an offline-first design, not just error handling for a dropped connection.

Our Approach

We assess whether cross-platform genuinely fits before proposing it, including what platform-specific capability the product might need later, not just what it needs at launch.

For connectivity-sensitive products, offline behaviour is designed from the data layer up, not added as a fallback once the online-only version is built.

Questions

Cross-Platform Apps FAQs

Should we build cross-platform or native for our app?
It depends on what the app needs to do and how much platform-specific capability matters. Cross-platform is usually right for most business apps; native makes more sense when you need the newest platform APIs immediately or truly platform-specific performance. We will tell you which fits before proposing either.
Flutter or React Native, which do you recommend?
It depends on your existing team and product. React Native is a strong fit if you already have React expertise or a React web product to share code with; Flutter tends to give more consistent UI behaviour across platforms out of the box. We make this call based on your specific situation, not a default preference.
Can the app work reliably in areas with poor connectivity?
Yes, that is a design requirement we build for specifically, with local data persistence and sync logic, rather than an app that simply shows an error when the connection drops.
Can we start cross-platform and move to native later if we need to?
In some cases, yes, particularly if the initial architecture anticipates it. It is worth raising this possibility during initial scoping so the app is not built in a way that makes a later native migration harder than it needs to be.
