How to choose a React Native development company
A strong React Native development company proves production ownership: live app links, backend/API role, store-release process, QA, maintenance and pricing after discovery. Do not choose by hourly rate or sales deck alone - ask for a scorecard, references and a post-launch responsibility plan.
Why an agency ranking is not enough
Directories such as Clutch and DesignRush help you build a shortlist: you can see reviews, location, rates and typical budgets. That is a good start, but a ranking does not answer whether a company can deliver your app, backend, store release and post-launch maintenance.
Toptal and similar platforms are useful for finding individual React Native experts. That is a different decision from choosing a product delivery company. A freelancer or contractor can be excellent on a small scope, but does not automatically own discovery, QA, App Store review, ERP integrations and maintenance planning.
Choosing a partner should therefore look like risk assessment, not a portfolio contest. The best vendor can show production evidence and say what they do not know before DDT.
7 questions before you sign
Good answers are specific: app names, team roles, publication timeline, sample QA report. Avoid agencies that say “we did similar” with no store link.
GMI Software: 50+ store apps, React Native with Expo and TypeScript, DDT plus fixed price after discovery, full code handover. We also deliver NestJS/Medusa backend and publication - one partner instead of vendor ping-pong.
- Show live App Store and Google Play apps - with links, not mockups.
- Who builds backend, ERP integrations and mobile API?
- Do you offer fixed price after discovery (DDT) or T&M only?
- What is store submission, compliance (privacy, data safety) and update process?
- Who owns code and repositories after delivery?
- How do you measure quality - E2E tests (Maestro/Detox), crash-free rate, code review?
- Industry experience (commerce, B2B, health, IoT)?
Scorecard: how to score a React Native partner
Use a simple 0-2 scorecard per criterion. Zero means no evidence, 1 means a claim or weak example, 2 means concrete proof: a link, document, process demo, reference call or sample deliverable from a past project.
Five criteria predict project success most: live store apps, discovery before pricing, backend/API ownership, release plus QA process and post-launch maintenance plan. Maximum score: 10. A partner below 7 points is risky for commerce, B2B and payment-heavy apps.
Do not score hourly rate alone. A lower rate without QA, architecture and release ownership often becomes the more expensive project after the first App Store rejection or after integrating with an unstable API.
Red flags when picking an RN agency
Portfolio is landing pages and screenshots only with no store links. Production React Native must pass Apple/Google review - an agency with no live apps failed that test.
No TypeScript and no New Architecture migration plan. In 2026 maintaining older architecture without an upgrade roadmap is technical debt you pay after a year.
“Backend on client side” with no clear API contract. If the mobile agency does not own API and your team has no capacity - integration eats months and budget.
Quote without discovery: fixed price on a 2-page brief is guessing. Real fixed price needs DDT with mocks, integration list and test plan.
No QA on the team or no E2E tests in the offer. Manual clicking before release will not catch checkout regressions after an Expo SDK upgrade.
Stack and skills your partner should have
Expo EAS (builds, OTA updates, credentials), TypeScript end-to-end, React Navigation, state management (Zustand/Redux - consistency matters, not fashion), REST/GraphQL integration, push (FCM/APNs), deep linking and analytics (Firebase/Amplitude).
Publication experience: App Store Connect, Google Play Console, data safety form, privacy nutrition labels, update and rollback process. First submission without an experienced partner means weeks of delay.
Backend under one roof: NestJS or Medusa API, shared monorepo types, API contract tests. GMI pairs React Native with TypeScript backend - API changes break the mobile build before production.
QA: Maestro or Detox on critical flows (login, cart, payment), Sentry for crash-free monitoring, code review before merge. Not a premium option - minimum for commerce and payments.
Agency, freelancer, staff augmentation or product team?
A freelancer makes sense when scope is small: a fix, prototype, 1-2 screens, ready API and someone on your side owns QA and release. Risk rises when the freelancer must also design architecture, backend, tests and submission.
Staff augmentation makes sense when you already have a product owner, tech lead, QA, release process and architecture. You buy capacity, not product responsibility. It is strong for a mature team, weak for a company creating its first mobile channel.
A product team or ownership-driven agency fits when the app affects revenue, retention, operations or brand reputation in stores. The partner should then deliver discovery, UX, React Native, backend/API, QA, release and maintenance.
Nearshore vs local agency vs offshore
Nearshore (e.g. Poland for EU/UK/US clients): time overlap, rates 30-50% lower than US at same seniority, English delivery, EUR/USD invoices. GMI works with clients from Germany, UK, US and Nordics in this model.
Local agency in client country: higher cost, easier on-site meetings. Makes sense when full on-site is mandatory for the whole project - rare with React Native and agile.
Cheapest offshore rates: communication, team rotation and code review quality risk. On ERP integrations and compliance (PCI, medical) rate savings are often illusion after rework cost.
What matters: not country, but store references, DDT process, fixed price and whether the partner owns backend and release.
Pre-RFP checklist
GMI runs this process with clients regularly - if you have a brief, we reply with ranges in 48h and propose DDT for fixed price.
- App type, integration list, publication deadline, compliance needs.
- Whether backend exists, budget range and who will be product owner on your side.
- Shortlist 3 agencies with live store apps - compare offers after DDT, not hourly rate alone.
- Clutch/G2 and a reference call (not just a logo on the website).
- PL/EN requirement for content if the app or sales assets are bilingual.
Next step: shortlist audit
If you have a shortlist of 2-3 React Native companies or an app brief, GMI can help evaluate scope, risks and realistic budget. Within 48h we reply with ranges and a recommendation on whether to enter DDT for fixed price.

Frequently asked questions
- Agency or freelancer?
- Freelancers cost less on tiny scope (1-2 screens, ready API). Agencies reduce risk on integrations, QA, store submission and post-launch care. For commerce and payments we recommend an agency with fixed price after DDT.
- How do you verify React Native agency references?
- Ask for App Store/Google Play links, not PDF portfolios. Check last update date, rating and reviews. Ask: “Who built that app’s backend?” and “How long did first store publication take?”
- Does GMI also build app backends?
- Yes - NestJS, MedusaJS, ERP integrations. One TypeScript team for mobile and API, shared types, lower integration risk. Our recommended model for commerce and B2B.
- What does an app from a good RN agency cost?
- GMI ranges: loyalty MVP EUR 18k-32k, commerce EUR 38k-70k, B2B with integrations EUR 55k-95k. Initial estimate in 48h, fixed price after DDT.
