Building separate iOS and Android apps doesn't just double your budget - it doubles your timelines, your maintenance burden, and the number of things that can go wrong between two codebases drifting apart. At Brainspack, we build high-performance cross-platform applications using Flutter and React Native that deliver a genuinely native-like experience on both platforms simultaneously - from a single, clean codebase. You ship faster, spend less, and get an app your users can't tell apart from a platform-native build. And we don't disappear after launch - we stay with you as your long-term development partner.
Every cross-platform project we take on starts with the specific problem a business is trying to solve - not a technology preference. We build the right thing for your users, your timeline, and your budget.
Your JavaScript team shouldn't have to learn Swift and Kotlin to build a mobile app - and you shouldn't have to hire platform specialists for every new feature. React Native lets us build a single codebase that compiles to genuinely native iOS and Android components, using your existing JavaScript knowledge and delivering the performance and feel users expect from a platform-native app. One codebase. Two platforms. No compromise on the user experience.
When visual consistency, animation quality, and pixel-perfect UI matter - across iOS, Android, web, and desktop - Flutter is the right tool. Dart compiles directly to native ARM code, meaning Flutter apps are fast by default, not fast for a hybrid. We build Flutter applications with rich, expressive interfaces that perform identically across every platform your users are on, with a single codebase your team can maintain without platform-specific expertise.
A cross-platform app that looks like it was designed for one platform and ported to another loses user trust immediately. We design interfaces that feel native to each platform - following iOS Human Interface Guidelines and Android Material Design principles - while maintaining a consistent brand identity across both. Users get an experience built for them. Your brand looks intentional, not compromised.
A cross-platform frontend is only as good as the backend it connects to. Slow API responses, unreliable authentication, inconsistent data across platforms, and poor offline handling are the hidden killers of cross-platform app experience. We build and integrate robust backend services - REST APIs, GraphQL, real-time connections via WebSockets - designed specifically to support cross-platform performance, offline capability, and consistent behaviour across iOS and Android.
Cross-platform doesn't mean test once, ship everywhere. Device fragmentation, platform-specific behaviours, and App Store versus Play Store submission requirements mean testing has to be rigorous and deliberate. We test across real devices - not emulators - covering the actual handsets your users own, handle both store submissions, and manage compliance requirements. Your launch is controlled and confident, not hopeful.
A cross-platform codebase makes maintenance cheaper - but only if it's been built cleanly. Platform OS updates, new device sizes, API deprecations, and changing store requirements don't stop after launch. We provide proactive maintenance that keeps your app stable, compliant, and performant as the platforms evolve around it. One team managing everything, not two
Using the wrong cross-platform framework for your use case - or a well-chosen framework implemented poorly - produces an app that feels like a compromise. We select between Flutter and React Native based on your specific product requirements, performance needs, and team context. We don't have a default preference; we have a structured decision process. Every tool we use is documented, your team is trained on it, and the codebase is handed over with no proprietary lock-in.
Too many Cross-Platform projects fail not because the technology doesn't work, but because the problem wasn't properly defined, the data wasn't ready, or the solution was built in isolation from the people who'd actually use it. Our process is built to avoid all three.
We define the platform goals and technical requirements before choosing any framework - so you know exactly what we're building before development starts.
We design for both iOS and Android, considering platform-specific navigation and user experience patterns while maintaining a consistent cross-platform brand identity.
Clean, well-structured single-codebase development with deliberate platform-specific adaptations, plus weekly updates and direct access to your project lead.
Rigorous testing across real iOS and Android devices, with app store submissions, platform guidelines, and compliance requirements fully managed to ensure a confident launch.
Ongoing OS compatibility updates, security patches, performance monitoring, and feature development. One codebase, one team, one point of contact.
A well-built cross-platform codebase means updates, bug fixes, and new features are deployed to both platforms simultaneously - no divergence, no duplicate work.
Not emulators. We test on the actual devices your users are running - so problems are caught by us before they're found by your customers.
Full documentation, clean architecture, and handover training. The codebase isn't dependent on us to maintain - any competent React Native or Flutter developer can pick it up.
We build cross-platform apps that pass the "is this native?" test with real users. Performance, animations, and platform feel are never sacrificed for the convenience of shared code.
Strategy, design, development, testing, store submission, and post-launch support - one team, full accountability.
