A React Native app development company builds one codebase that runs on iOS and Android. The framework is mature, and Meta and Microsoft both list it in their own products on the official React Native showcase. The harder question for a buyer is which team to trust with it. This guide shows what to check, in the order that saves you the most risk.
Much of the 2026 advice on this topic comes from agencies that sell React Native work, including Devico and GMI Software, both cited below. We treat it as informed opinion from people with something to sell, not neutral research, and we say so where it matters.

Why the way you vet a React Native team has changed
React Native 0.76, released in October 2024, turned on the New Architecture by default, according to the official release post. Devico’s 2026 guide adds that React Native 0.82 removed the fallback to the old architecture, so every current app runs on the new one.
The practical effect is that a portfolio full of older apps tells you less than it used to. A team can have years of React Native work and still never have migrated a production app off the old bridge. Devico cites the 2025 State of React Native survey (3,501 responses): 74% of respondents had used the New Architecture, but only 24% had built a Turbo Native Module. Running on the new architecture and understanding it are different things, so ask what the team has actually built or migrated.
If you are still weighing frameworks, our guide on the differences between native, hybrid and web apps and the piece on the future of cross-platform app development explain where React Native fits. Our React Native glossary entry covers the basics.
Five checks before you compare quotes
- Live apps, not mockups. GMI Software tells buyers to ask for App Store and Google Play links. Production apps have passed store review, and landing pages and screenshots have not.
- New Architecture experience. Ask which libraries broke during a migration, what changed after cutover and what showed up in crash reports. Devico says engineers who did the work answer with specifics, and the rest speak in generalities.
- Native skills. Devico recommends engineers who can write Swift and Kotlin, not only wire up packages, because custom native modules are where projects stall.
- Release and QA process. Ask who handles store submission, privacy and data-safety forms, end-to-end tests and crash monitoring. GMI names Maestro or Detox for tests and Sentry for crash reports as reasonable minimums.
- Ownership. Confirm in writing that you own the code, the repositories, the signing credentials and the store accounts. Both sources flag this as a cheap thing to settle before you sign and an expensive one to fix later.
Pick the engagement model before the vendor
Devico’s framing is simple: decide who owns technical direction in your company. The three usual models are below, summarized from its guide.
| Model | Best for | Who manages delivery | Main trade-off |
|---|---|---|---|
| Staff augmentation | Teams with an engineering process that need more React Native capacity | Your team | You keep control but carry the management load |
| Dedicated team | Ongoing mobile roadmap with no full mobile team in house | The vendor, against your priorities | Less day-to-day control |
| Fixed scope project | A clear migration, first version or standalone module | The vendor, to an agreed scope | Predictable start, costly changes later |
If nobody on your side can review an architecture decision, staff augmentation tends to drift. A dedicated team with its own technical lead is the safer pick in that case.
Red flags worth walking away from
- A portfolio of screenshots with no store links.
- A fixed price on a two-page brief. GMI says a real fixed price needs a discovery phase with mockups, an integration list and a test plan.
- No test engineer on the team and no end-to-end tests in the offer.
- No plan for upgrading to the current React Native version.
- Resistance to meeting the delivery lead. Devico points out that a polished proposal shows the vendor can sell, not that the assigned engineers can build.
Where to look for shortlists
Directories such as Clutch and DesignRush help you build a shortlist, as GMI notes, but a ranking does not prove a team can ship your app. Use them to find names, then run the five checks above. You can also browse vetted agencies on our top companies directory and our list of top custom software development companies.

Budget and timeline
We have not quoted prices here because we could not verify current figures from an independent source. Our separate guide on the cost to develop a React Native app covers what drives the number, and the post on mobile app development ROI helps you judge whether the spend makes sense.
On timing, Devico says a mid-market vendor selection commonly takes four to eight weeks, plus one to three weeks after signing before a new team is productive. If you want to validate the idea first, building an MVP first keeps the early commitment small.
Frequently asked questions
What does a React Native app development company do?
It designs, builds, tests and releases mobile apps for iOS and Android from a shared JavaScript or TypeScript codebase, and usually handles store submission and maintenance. Backend and API work varies by firm, so ask who owns it.
How do I choose a React Native development company?
Check live store apps, New Architecture experience, native Swift and Kotlin skills, release and QA process and code ownership. Compare price after those five.
Is React Native still worth choosing over Flutter?
Devico says both are mature and the gap is narrower than many comparisons suggest. If your team already uses React on the web, React Native can make it easier to move engineers between web and mobile. Our guide on hiring Flutter developers covers the other side.
Should I hire a freelancer or a company?
A freelancer suits a small, well-defined task. For an app you expect to run for years, a company gives you replacement capacity, reviews, QA and contractual continuity, which reduces the risk of one person holding all the context.
Do I need New Architecture experience for a new app?
New projects run on it by default, so the question is depth. A team that has migrated production apps is more likely to spot library and native module problems early.
How much does a React Native app cost?
It depends on scope, platforms, integrations and the team. We do not quote figures we cannot verify. Ask for an itemized quote that includes testing, store release and maintenance.
How long does it take to pick a vendor?
Devico puts a typical mid-market process at four to eight weeks, with staff augmentation often faster and regulated companies often slower.
