React Native app development cost in 2026
In 2026, a production React Native app typically costs EUR 18,000 - 32,000 for a loyalty MVP, EUR 38,000 - 70,000 for mobile commerce and EUR 55,000 - 100,000+ for B2B, IoT or compliance-heavy apps. API readiness, integrations, QA, store release and post-launch maintenance drive the difference.
What affects mobile app cost?
React Native app cost is not “screen count”. It is feature scope, backend integrations (REST, GraphQL), in-app payments, push notifications, offline mode, compliance (GDPR, PCI, medical MDR) and quality of the existing API the app connects to.
React Native ships iOS and Android from one codebase, but it does not remove product work: discovery, UX, testing, store release, analytics, crash monitoring and maintenance still need budget. If the backend does not exist or needs rewriting, app cost grows by the API layer, for example NestJS or Medusa.
Poland nearshore vs US rates: hourly-rate difference can be large, but the buyer should care more about the full accountability model. GMI prices scope after DDT, works in English with EU/UK/US clients and combines React Native, backend and app-store release in one team.
Ranges by app type
Loyalty MVP (account, points, push, basic catalogue, analytics): EUR 18,000 - 32,000. Timeline: 3-4 months. Assumption: ready API or a simple backend without complex business rules.
Mobile commerce app (catalogue, cart, payments, headless/Medusa integration, CRM, push, offline cache): EUR 38,000 - 70,000. Timeline: 4-6 months. This is the typical range for brands that want an owned sales channel, not just a website wrapper.
B2B or operational app (price lists, limits, approval workflows, roles, offline, ERP/WMS/CRM sync): EUR 55,000 - 95,000. Timeline: 5-8 months. Needs stable API, regression tests for business rules and a clear process owner on the client side.
IoT/BLE, medical or financial compliance (audit trail, encryption, certification, custom native modules): EUR 70,000 - 100,000+. Each regulatory requirement creates a separate QA, documentation and release-risk block.
What competitor guides show well, and what they usually miss
Spdload gives a useful simple / mid-range / complex app split and team-location benchmarks. Appinventiv correctly reminds buyers that maintenance is often estimated around 20% of development cost per year. Those are good starting points, but too generic for commerce or B2B buyers.
The biggest gap in cost articles: few show what is inside the price and what is excluded. Two EUR 40,000 quotes can mean very different things: one includes UX, QA, store release, Sentry and payment integration; the other covers only Figma-screen implementation.
This article therefore breaks cost down by business type and operational risk. A loyalty app, commerce app, B2B ERP app and regulated app have different cost drivers even if they have a similar number of screens.
Project phases and what is included
Discovery (DDT): 1-3 weeks, EUR 3,500 - 12,000 depending on complexity. Output: UX mocks, architecture, integration list, test plan, risk map and a fixed-price build quote. Without this, a cheap quote is usually guessing.
Build: 2-week sprints, demo each iteration, code review, E2E tests (Maestro/Detox), CI/CD via Expo EAS. Backend enters scope only when agreed in DDT: NestJS, ERP integrations, Medusa API, webhooks, data migration.
Release: App Store and Google Play submission, compliance review (privacy policy, data safety form), push setup (FCM/APNs), crash monitoring (Sentry) and analytics. GMI guides clients through first submission and plans the update process.
Post launch: run EUR 2,000 - 6,000/month (SLA, monitoring, small iterations) or dedicated developer from EUR 5,200/month. We usually plan Expo SDK and React Native upgrades 1-2 times per year before they become an emergency project.
Hidden costs that should be in the budget
A low quote often skips things you will pay for later: Apple Developer and Google Play accounts, CI/CD setup, staging/production environments, error monitoring, product analytics, privacy policies, Data Safety form, App Store review and SDK update planning.
Expo is not “free app hosting”. The official EAS pricing has a Production plan at USD 199/month plus usage, build credits and update-MAU limits. This is small compared with development, but it should be explicit in TCO.
The most expensive hidden cost is a weak API. If the app waits for endpoints, duplicates business logic or handles unstable ERP data, mobile cost rises even when React Native code quality is good.
Comparison: nearshore, US agency, freelancer
Freelancer: lower rate, but without QA, PM and architect delay and rework cost rise. Makes sense on very small scope (1-2 screens, ready API).
US agency: competitor benchmarks often show USD 150-200/h for the US/Canada. This can make sense for market proximity and onsite workshops, but PM, QA and senior architecture cost must be included.
GMI nearshore (Poland): EUR/USD fixed price after DDT, 50+ store apps, full code handover. One partner for React Native, NestJS/Medusa backend and release - less vendor ping-pong.
How to spot a quote that is too cheap
A quote below EUR 15,000 can be realistic for a prototype or very simple MVP, but rarely for a production commerce app with payments, store release and maintenance. If a vendor says “we can do everything” but does not ask about API, analytics, QA and release process, it is not an estimate yet - it is selling hope.
- No separate line for discovery and architecture.
- No QA, regression testing or App Store / Google Play submission.
- No questions about backend, data source and API ownership.
- No post-launch maintenance or SDK update plan.
- No clear answer on who owns source code and developer accounts.

Frequently asked questions
- How long for an MVP?
- Typically 3-5 months to store production with RN plus Expo, depending on integrations and API readiness. B2B with ERP: 5-7 months.
- Does the cost include backend?
- Depends on DDT scope. GMI often delivers React Native plus NestJS/Medusa in one fixed price - one partner, shared TypeScript types, lower integration risk.
- What does app maintenance cost after launch?
- SLA with monitoring and small iterations: EUR 2,000 - 6,000/month. Dedicated developer: from EUR 5,200/month. We plan OS and Expo SDK upgrades proactively.
- Can I get a fixed price for the app?
- Yes - after DDT we issue a fixed-price guarantee on agreed scope. Technical blockers inside scope are on GMI.
