How to choose a React Native agency in 2026

Short answer

There is no single best React Native agency, and anyone who tells you otherwise is selling something. The right studio depends on the size of your project, your deadline and how much hand-holding you actually need. A specialist MVP shop that ships in 4 to 8 weeks solves a very different problem than a 40-person agency staffing a six-month build. This guide walks through the criteria to judge any React Native partner, so you can compare them on facts instead of logos.

Two kinds of studios, two kinds of problems

Broadly, the market splits in two.

On one side, fast MVP studios. Small teams, a fixed stack, delivery in a handful of weeks, prices you can often find on the website. They exist to get a first version into the stores without you building an internal team. Inyka sits here.

On the other side, established agencies. Bigger teams, formal processes, capacity to run several people on your project for months. They handle structured builds, complex governance, enterprise procurement. Their entry price is higher and their sales cycle is longer.

Neither is better in the abstract. A founder validating an idea does not need enterprise governance. A bank rebuilding a customer app does not want a two-person studio. Pick the shape that fits the job, then judge the individual studio on the criteria below.

Portfolio and real references

Ask for a name, a sector, and an app you can actually download. That is the bar.

Vague case studies with the client name redacted and no live link are a warning sign. Sometimes there are real NDAs, fine. But if everything is confidential and nothing ships to a store you can open, you are trusting a slide deck.

Look at the apps themselves. Open them, use them, check the store reviews. An agency that has shipped React Native apps that people actually use will happily point you at them.

Stack and specialization

A studio that does "web, mobile, no-code and AI agents" is spread thin. React Native is deep enough that specialization shows in the result.

Ask what the default stack is and why. A clear answer, something like React Native, Expo, a managed backend and TypeScript, tells you they have a repeatable way of working. A shrug, or "it depends on the project every time," usually means you are paying for them to figure it out on your build.

Also ask who actually writes the code. A 50-person agency can absolutely subcontract your project to an offshore junior. Ask to speak to the tech lead who will be on your project, not just the salesperson.

Pricing transparency

There are two models: a fixed price announced before you sign, or a per-project quote that lands after discovery.

A fixed price protects you against scope drift. You know the number before committing, and the studio carries the risk of estimating badly. A time-and-materials quote can make sense for genuinely open-ended work, but it puts the overrun risk on you.

Whatever the model, compare scope at the same price, not just the final figure. A €12,000 quote covering design, build, store publication and code handover beats a €9,000 quote that quietly excludes half of that. Cheaper is not cheaper if you pay the difference later.

Code ownership

This one is non-negotiable, and people forget to ask.

Is the source code transferred to you at the end? If not, you are dependent for life, and you will pay for it on every future change. Ask for the assignment clause in the contract, in writing. A studio confident in its work has no reason to hold your codebase hostage.

Timeline and commitment

An estimate is marketing. A date in the contract is a commitment.

Ask for a contractual delivery window, not just a cheerful "about six weeks." Then ask what happens if they miss it. The answer tells you how seriously they take their own timeline.

Fast is good, but only if the studio can also say no. A shop that promises to cram everything into the same short window regardless of what you ask is either overselling or about to cut corners.

Communication and scoping method

How does the studio turn your rough brief into a locked scope? This is where most projects quietly go wrong.

A good partner runs a real scoping step early: what is in the first version, what is explicitly out, what the data model looks like. If the answer to "how do you scope?" is vague, you will pay for that vagueness later in change requests and delays.

Also gauge plain responsiveness. Slow, evasive answers before you have paid anything rarely improve after the contract is signed.

A quick decision guide

Simple MVP, tight budget (under €15k), short deadline (under 6 weeks). Look at specialist MVP studios first. Ask each for a fixed quote on your exact scope and compare what is covered.

Structured project, €30k to €80k, a full team for three months. Established agencies are better sized for this. Prioritize process, team capacity and a clear scoping method.

Large enterprise, €100k plus, complex governance. Go with agencies that have enterprise references and expect longer sales and procurement cycles.

No in-house tech, want a long-term partner with maintenance. Weight ongoing support, documentation quality and how the studio handles handover and updates.

The criteria that actually matter

Beyond the sticker price, check every one of these before signing:

• Fixed price announced before signing, or open quote? A fixed price protects against drift.
• Is the source code transferred to you at the end? If not, you are locked in. Get the assignment clause in the contract.
• Who actually writes the code? Ask to talk to the tech lead on your project.
• Verifiable references. A name, a sector, a live app in the stores. If it is all confidential or fuzzy, that is a signal.
• Contractual delivery commitment. A hard date in the contract, not a marketing estimate.
• Scoping method. How they turn your brief into a frozen scope. A vague answer means a bigger bill later.

Where Inyka fits

Full disclosure: we are one of these studios, so read this with that in mind. Inyka is a French React Native studio positioned in the fast, fixed-price MVP segment. We ship iOS and Android apps in 4 to 6 weeks, announce the price before signing, and transfer the full source code to the client at the end. The stack is React Native, Expo, Supabase and TypeScript, and we do React Native only, no no-code and no Flutter.

We are not the right choice if your project needs four months, €80k and heavy governance. For that, an established agency with a formal process is a better fit. Judge us on the same criteria as everyone else on this list, that is the whole point.
