React Native Development Services for Startups and SMEs

What this service is and who needs it

React Native development services cover building a mobile app from a single codebase that runs on both iOS and Android, using the React Native framework maintained by Meta. This is for startups that need to launch on both app stores without building two separate native apps, and for SMEs or SaaS companies that already have a web product and want a mobile app without doubling their engineering team.

If you are comparing "build native twice" against "build once in React Native," you are really deciding how much budget and time you can spend before your first mobile release. For most companies outside of gaming or apps with heavy camera and sensor work, one React Native codebase is the faster, cheaper path to a real product in the App Store and Google Play.

What you get: deliverables and scope

A proper React Native engagement is not just code handed over at the end. It should include:

• A working app on both platforms built from one shared codebase, typically 90-100% shared code depending on how much native functionality your app needs
• UI/UX design or conversion of your existing designs into working screens, with attention to platform differences between iOS and Android
• API integration connecting the app to your backend, whether that is an existing system or one built alongside the app
• Native module bridging for anything React Native does not cover out of the box, such as certain payment SDKs, biometric login, or hardware-specific features
• Testing across real devices and OS versions, not just simulators
• App store submission handling Apple and Google's review requirements, provisioning profiles, and store listings
• Source code and documentation, handed over in full, with no vendor lock-in

What is usually not included unless you specify it upfront: ongoing app store account management, paid marketing or ASO (app store optimization), and ongoing maintenance past an agreed warranty window. Ask about these before you sign anything, because some agencies quietly bundle them in while others charge separately.

If your app needs more than mobile, our cross-platform app development services page covers how React Native fits alongside web and backend work in a single project.

How the engagement runs

A React Native project that goes well follows a predictable shape. Here is the order most competent teams use:

1. Discovery (1-2 weeks) - scoping features, reviewing any existing designs or backend, and writing down what "done" means for version one
2. Design (1-3 weeks) - wireframes and UI screens, often running partly in parallel with discovery for simple apps
3. Build (6-16 weeks) - development in sprints, usually 1-2 week cycles with a demo at the end of each
4. QA and testing (ongoing through build, plus 1-2 weeks dedicated at the end) - functional testing, device testing, and regression checks before submission
5. Launch - app store submission, which can take anywhere from a few days to a couple of weeks depending on Apple and Google's review queues
6. Support - a warranty period (commonly 30-90 days) for bug fixes, followed by an optional ongoing maintenance arrangement

You should expect a single point of contact, usually a project manager or lead developer, even if 3-5 people are touching the code behind the scenes. Weekly check-ins and a shared task board (Jira, Trello, Linear, whatever the team uses) are the minimum bar. If a prospective vendor cannot tell you who you will talk to day-to-day before you sign, that is a warning sign, not a detail to sort out later.

A functioning MVP with 8-12 core screens, basic auth, and one or two backend integrations is a realistic scope for a first release. Anything beyond that is a second phase, not a bigger version one.

What it costs

Cost bands for React Native work are driven by hours, and hours are driven by how many screens, how much custom logic, and how much native work (camera, payments, push notifications, offline mode) the app needs. Using a realistic blended rate for this kind of work, here is what the bands actually look like:

What moves these numbers up or down:

• Design-from-scratch versus design-in-hand adds 15-25% of the budget if you need UI/UX built, not just implemented
• Native modules (custom camera processing, Bluetooth, certain payment gateways) add hours that pure React Native screens do not
• Backend work, if you do not already have an API, is usually a separate line item on top of the app itself
• Testing depth - a team doing device-by-device manual QA across both platforms costs more hours than one relying mostly on simulators and automated tests
• Ongoing maintenance after launch typically runs separately, often billed monthly or on a smaller retainer basis once the initial build is done

Fixed price versus time-and-materials is worth a real decision, not a default. Fixed price protects your budget if scope is well-defined upfront. Time-and-materials suits projects where you expect to learn and adjust scope as you build, which is common for first-time products.

How to judge a provider for this work

Ask any agency, including us, these questions before you commit:

• How many React Native apps have you shipped to production, not just started? Ask to see one live in the App Store or Google Play.
• What percentage of your codebase is typically shared between iOS and Android on past projects, and why does it vary?
• Who writes the tests, and what gets tested before you submit to app stores?
• What happens when React Native or a major library you depend on gets a breaking update after launch? This tells you whether maintenance is a real plan or an afterthought.
• What is not included in your quoted price? Get this in writing, specifically around app store fees, third-party SDK licensing, and post-launch support.
• Can I speak to the actual developers, not just a salesperson, before signing?

If you want a deeper walkthrough on vetting agencies specifically, we have covered this in more detail in Choosing a React Native App Development Agency and React Native Development Agency: How to Choose One. Both are worth reading before you take a call with anyone, including us.

Our own engineering team's take: the agencies that struggle on React Native projects are almost never the ones who lack React skills. They struggle because they underestimate native bridging work and app store review delays, then both show up late and over budget.

React Native versus the alternatives

React Native is not the only path to mobile, and it is not always the right one. Here is how it stacks up against the common alternatives:

React Native's own documentation, maintained by Meta, states the framework is designed so teams can "build apps with native capabilities using JavaScript and React," which is exactly the trade-off most business apps are looking for: native feel without maintaining two codebases.

Proof points worth knowing

Dignizant Technologies LLP works with startups, SMEs, SaaS companies, and businesses worldwide on custom web, mobile, AI, and software development. React Native sits inside a broader mobile and cross-platform practice, not as a standalone offering disconnected from design, backend, QA, or AI work. If your app needs AI features like a chat assistant or automated support, our ChatGPT integration services pair naturally with a React Native build. If your app handles payments or financial data, our fintech software development work covers the compliance and security layer that financial apps need on top of the mobile build itself. And once the app is built, quality does not end at launch, which is why dedicated software testing and QA services matter as much as the initial build.

How to start

If you have an app idea or an existing product that needs a mobile version, the next step is a conversation, not a proposal written in the dark. Bring whatever you have, whether that is a rough sketch, a full spec, or just a problem you know needs solving, and reach out to Dignizant Technologies LLP to talk through scope, timeline, and real numbers before anything is signed.
