Mobile apps your users actually want to use.
Cross-platform iOS and Android apps built with React Native — performance-first, pixel-perfect, and delivered on schedule. From patient-facing portals to operations dashboards.
Mobile is not a second-class channel. For most of our clients' users — patients checking appointments, hotel guests managing reservations, field staff updating records — mobile is the primary interface. We treat it accordingly.
Flexonixs builds cross-platform mobile apps with React Native, allowing us to ship to iOS and Android from a single codebase without sacrificing the native performance or platform conventions that users expect. Our apps pass App Store and Play Store review on the first submission, every time.
We've built healthcare apps that handle sensitive patient data with biometric auth and offline mode. Hospitality apps that manage room status for housekeeping staff across multiple properties. Startup apps that went from whiteboard to App Store in 8 weeks. The use case changes — the quality standard doesn't.

Common questions
Do you build native (Swift/Kotlin) or cross-platform apps?
We build cross-platform apps with React Native. For 95% of use cases, React Native delivers native-quality performance and user experience at significantly lower cost than two separate native codebases. For the rare use cases requiring hardware-level access or extreme performance (AR, heavy video processing), we evaluate native development separately.
How long does mobile app development take?
A focused MVP with core features typically takes 6–10 weeks. A full-featured app with complex integrations, admin dashboards, and thorough QA takes 12–20 weeks. We define scope precisely before committing to a timeline.
Do you handle App Store and Play Store submission?
Yes. We handle the complete submission process — app certificates, provisioning profiles, store listings, screenshots, and metadata. We've never had an app rejected on first submission.
Can you add mobile to our existing web product?
Yes. If your web product has a well-structured API, adding a React Native mobile app is straightforward. We evaluate the existing API during discovery and flag any changes needed to support mobile-specific requirements (push notifications, offline sync, etc.).
