Cross-Platform App Development

Cross-Platform App Development

Cross-platform app development with React Native and Flutter - one codebase for iOS and Android, faster time-to-market, and native-level performance without building twice.

Overview

LNOKS builds cross-platform mobile applications using React Native or Flutter, depending on the team's existing stack and the product's animation and platform-API needs. Each project ships to both iOS and Android from a single codebase, with shared business logic, platform-specific native modules where required, and CI/CD pipelines for parallel store submissions. Founded in 2022, LNOKS has delivered 40+ products with a 5.0 Clutch rating and 96% client re-engagement. Cross-platform engagements pair with backend API and design system work so the apps do not ship coupled to a single backend implementation that becomes expensive to swap later.

Frequently Asked Questions

Frequently asked questions

Yes, mobile apps can integrate with your existing systems, and we do this frequently — connecting apps to CRMs, ERPs, internal APIs, and third-party services. We pair cross-platform builds with backend API work so the app is not coupled to a single backend implementation that becomes expensive to swap later. Integration points are defined during scoping so data flows are clear before development starts.

Yes, you can migrate to fully native apps later if business needs change, and we design the architecture to keep that path open. Shared business logic is separated from the UI layer, and platform-specific native modules are already isolated where the product needs them. That structure means a later native rebuild replaces the shell, not the entire system your business logic lives in.

We build both native and cross-platform mobile apps, and we recommend the best option based on performance needs, budget, and time-to-market. For cross-platform work we use React Native or Flutter, chosen by your team's existing stack and the product's animation and platform-API needs. Either way, both iOS and Android ship from the same project, with CI/CD pipelines handling parallel store submissions.

For most business and SaaS applications, cross-platform performance is comparable to native solutions. Where a feature genuinely needs deeper access — heavy animation or platform-specific APIs — we add native modules rather than compromising the experience. We weigh those needs when choosing between React Native and Flutter, so performance-critical paths are identified during scoping instead of discovered after launch.

We ensure good mobile user experience by designing mobile-first UX, testing on real devices, and optimizing performance and interactions for touch-based usage. Cross-platform builds pair with design system work, so screens stay consistent across iOS and Android while respecting each platform's conventions. Testing on physical devices, not just simulators, catches the gesture, keyboard, and performance issues that emulators miss.

Cross-platform development is ideal when you want faster time-to-market and shared functionality across iOS and Android. One codebase means one team, shared business logic, and features that land on both platforms simultaneously through parallel store submissions. It suits most business and SaaS applications; if your product depends on heavy animation or deep platform-API access, we assess whether native modules or a native build fits better.

We primarily use modern frameworks such as React Native to balance speed, performance, and maintainability, and we also build with Flutter where it fits better. The choice depends on your team's existing stack and the product's animation and platform-API needs. Both frameworks ship iOS and Android from a single codebase, with platform-specific native modules added only where the product requires them.
