React Native App Development for Startups, Enterprises, and Healthcare
WTT Solutions is a React Native app development company with a decade of cross-platform mobile engineering across healthcare, fintech, marketplace, and enterprise verticals. React Native's JavaScript/TypeScript foundation lets your existing web team contribute to the mobile codebase from day one — sharing 70–85% of logic while rendering real native UI components on both iOS and Android, without the cost of maintaining two separate native engineering teams.
Healthcare is our deepest vertical. We ship React Native apps for US clients who require HIPAA-compliant architecture, EHR integrations (HL7/FHIR), and App Store compliance for regulated categories — industry depth lives on our healthcare landings below. Our engineering teams cover the full delivery cycle: discovery, architecture, UX, development, native module bridging, QA, store submission, and post-launch support. For stack-agnostic strategy, see our custom mobile app development hub, or explore our dedicated Flutter app development company page for a direct comparison.
React Native App Development Services We Offer
- FULL-CYCLE REACT NATIVE APP DEVELOPMENT FROM DISCOVERY TO STORE LAUNCH We own the entire delivery — product discovery, solution architecture, UI/UX design, React Native engineering, backend API integration, QA, App Store and Google Play submission, and post-launch iteration. One accountable React Native development company, not a chain of contractors.
- HEALTHCARE & HIPAA-COMPLIANT REACT NATIVE APPS FOR REGULATED INDUSTRIES HIPAA BAA-ready React Native architecture, FHIR and HL7 integrations, biometric auth, AES-256 encrypted local storage (Keychain on iOS, Keystore on Android), TLS 1.3 networking, and App Store regulated-category submission. We have delivered React Native mHealth apps and telemedicine platforms for US healthcare clients who cannot afford compliance shortcuts.
- ENTERPRISE REACT NATIVE APP DEVELOPMENT WITH SSO, OFFLINE SYNC, AND INTEGRATIONS React Native field-force tools, B2B mobile platforms, and enterprise productivity apps with SSO, offline-first architecture, push notifications, role-based access, and deep ERP or CRM connectivity. These enterprise React Native app development services are delivered as dedicated engineering pods for long-running programmes.
A serious React Native practice covers discovery, UX, architecture, JS/TS engineering, native module bridging, QA, store submission, and post-launch support. The value is accountable delivery: one team that owns performance, Bridge vs New Architecture decisions, backend contracts, and compliance when your product requires it.
At WTT Solutions, React Native delivery covers greenfield MVPs, growth-stage feature programmes, and regulated healthcare apps. When pixel-identical custom UI matters more than JS reuse, we may recommend our Flutter app development company practice instead — and we will say so in discovery.
If you are still comparing frameworks at a strategy level, start with our mobile app development services hub, then return here when React Native is the decided stack.
Relevance comes from the New Architecture (JSI / TurboModules / Fabric), Expo and bare-workflow maturity, and a large hiring market for React engineers who can contribute to mobile. It is not the default for every product: pixel-identical custom UI often favours Flutter, and deep hardware or MDM-heavy apps may still need native modules or full native.
WTT Solutions ships React Native, Flutter, and native Swift/Kotlin. We recommend React Native when JS/web reuse and dual-store velocity align with your economics — not because a blog post ranked it first this year.
Discovery always precedes commitment. We would rather lose a deal than start a React Native engagement with undefined scope, missing compliance owners, or an unspoken expectation that every native API has a maintained npm package.
Choose Flutter when you are starting greenfield without a large React codebase, when pixel-consistent UI across iOS and Android is a product requirement, or when complex custom animations dominate the experience. Choose native Swift/Kotlin when you need deep platform APIs (ARKit, HealthKit edge cases, Android enterprise MDM) that cross-platform abstractions still approximate poorly, or when you intentionally ship one platform only.
WTT Solutions ships all three. This page owns React Native. Compare stacks on our Flutter app development company page or the mobile app development services hub when you need a technology-agnostic recommendation.
Discovery always precedes commitment. We would rather lose a deal than force React Native into a product that needs Flutter UI consistency or deep native hardware.
MVP — $40,000 to $90,000 / 3–4 months. Dual-platform React Native MVP with core flows, auth, API integration, analytics, and store submission.
Growth — $90,000 to $180,000 / 5–8 months. Richer UX, offline sync, payments, push, CI/CD, and multiple third-party integrations.
Enterprise / Healthcare — custom quote. HIPAA/BAA, SSO, FHIR/HL7, dedicated pod, and audit readiness typically start above $200,000 depending on team size and programme length.
We estimate after a paid discovery phase. Fixed quotes before architecture are marketing theater — not engineering.
The largest cost driver is backend complexity and compliance — not whether the UI is React Native or Flutter. A simple CRUD React Native app is inexpensive. A telehealth client with real-time video, FHIR sync, and biometric auth is a different engineering problem entirely.
For a stack-agnostic cost framing, see our mobile app development services page.
Compliance is framework-independent — the risk is vendors who treat React Native as a UI kit and ignore PHI. For industry positioning, see our healthcare app development services and custom mHealth app development pages. This React Native spoke owns the engineering stack; those pages own healthcare intent.
Discovery always precedes commitment. We would rather lose a deal than start a regulated engagement with missing compliance owners or an unspoken expectation that npm packages alone solve HIPAA.
Staff augmentation fits when you already have mobile leadership and need capacity. Full-cycle delivery fits when you want accountable ownership from discovery to stores. For embedded engineers only, see our IT staff augmentation offering.
Discovery always precedes commitment. We would rather lose a deal than staff a React Native engagement with undefined scope or missing product ownership on your side.
Regulated apps add 2–4 weeks for HIPAA architecture, BAA setup, and store documentation. Undefined requirements are the number-one cause of slip — which is why we insist on paid discovery before locking a launch date.
We mitigate slip with a written discovery pack: user flows, API contracts, analytics events, Bridge vs New Architecture plan, and a compliance checklist signed before sprint one. That document is the single best predictor of on-time React Native launches.
If the previous vendor is gone, we can usually onboard a healthy React Native app in 2–4 weeks. If the codebase is structurally unsound, we scope a stabilisation phase before new feature velocity.
Modernisation paths we execute include migrating from the legacy Bridge to the New Architecture, replacing abandoned navigation or state libraries, introducing Detox or Maestro flows for critical journeys, and splitting monolithic JS modules into maintainable packages.
Stakeholders receive a living backlog in the tool you already use — Jira, Linear, or Azure DevOps — with acceptance criteria written so QA and product can validate without translating tribal knowledge.
New Architecture (JSI / TurboModules / Fabric) readiness is a discovery deliverable, not an end-of-QA surprise. Dependency audits run throughout delivery. That discipline is part of what separates a serious React Native engineering partner from a screen shop.
Tooling includes Expo or bare React Native CI patterns, GitHub Actions or Bitrise pipelines, Firebase Crashlytics or Sentry, and store-ready build flavors for staging versus production.
Native still wins for some hardware-heavy or OS-deep experiences. We flag those cases in discovery instead of forcing React Native into a bad fit — and we may point you to Flutter or native when that is honest.
We also profile JS-thread jank, startup time on mid-tier Android devices, and battery impact before release. React Native performance issues are usually architecture, list virtualisation, and Reanimated discipline — not the framework ceiling.
Rejection risk drops when compliance is designed up front. Treating store review as a final checklist is how launch dates slip.
Discovery always precedes commitment. We would rather lose a deal than start a React Native engagement with undefined scope, missing compliance owners, or store metadata left for the last week.
If your product needs a broader mobile strategy beyond React Native, use our mobile app development hub or the Flutter app development spoke.
Stakeholders receive a living backlog in the tool you already use — Jira, Linear, or Azure DevOps — with acceptance criteria written so QA and product can validate without translating tribal knowledge.
If someone sells you hybrid as 'the same as React Native but cheaper,' ask about animation budgets, offline reliability, and store rejection history. We recommend hybrid only when the product constraints truly match.
Discovery always precedes commitment. We would rather lose a deal than start a React Native engagement that should have been a simple internal Capacitor tool — or the reverse.
Most growth-stage and healthcare clients choose dedicated pods. Fixed-scope works when requirements are crisp. Augmentation works when your tech lead is ready to direct day-to-day work — often via the same IT staff augmentation bridge used for other mobile stacks.
Changing models mid-programme is possible: many clients start fixed-scope for MVP, then convert to a dedicated React Native pod once product-market fit is clear.
We offer basic maintenance, growth iteration, and managed product partnership tiers so support matches product maturity.
OS major releases from Apple and Google land every year. Budget 10–20 hours monthly for basic maintenance even if feature work pauses — or ratings and crash-free sessions will quietly decay.
For healthcare, React Native apps can sit on top of FHIR R4 APIs and HL7 interfaces when the integration layer is designed correctly. The hard part is rarely JavaScript — it is vendor quirks, auth scopes, and PHI handling. Our healthcare mobile engineers bring those patterns so React Native UI work is not blocked by integration surprises — industry depth for regulated products stays on our healthcare landings linked in the HIPAA FAQ above.
If your primary need is stack-agnostic mobile strategy rather than React Native specifically, start on our mobile app development services hub and we will route stack decisions from there.
