React Native app development agency: One codebase. Both phones.
We build your Android and iOS app from one React Native codebase, and the API, website and admin panel behind it. One team, one TypeScript stack, kept running.
Built for Trustiva Laboratory’s patients and sample collectors, and for RaasPaas.

React Native apps we built for Android and iOS, each with the website, admin panel and API behind it, built by the same team.
5.0 on Google · 21 reviews01 · Why it matters
The app is only half the job.
- An Android developer
- An iOS developer
- A separate web and API team
- One React Native team
Every app talks to a server: bookings, reports, users and payments live there, and your website and admin panel read the same data. When the app, the server and the website come from different suppliers, each change waits for all of them. A react native agency that only builds the app leaves that gap open. As a React Native app development agency, we build the whole thing in one TypeScript stack, from our office in Ahmedabad.
01
“The app and the website show different things.”
One API serves the app, the website and the admin panel, so a change shows up everywhere at once.
02
“Every fix needs two developers.”
Android and iOS share one React Native codebase: a fix is made once and goes into both apps.
03
“Our web team doesn’t know the app.”
The same people write the app, the server and the web system, in one language: TypeScript.
04
“If the agency goes, we’re stuck.”
You own the code, the database and every login. React Native and TypeScript are widely used, so another team can pick the code up.
02 · What we build
What our React Native app development agency builds
The app on the phone and the system it talks to, written by one team. As a React app development agency, we use React on the web and React Native on the phone.
On the phone
One codebase, two platforms.
Built with React Native and Expo.
Android and iOS from one codebase
The two apps share their screens and rules, so they look the same and change together.
Customer and staff apps
An app for the people who book and buy, and one for the team who visit, collect and report.
Testing and release
Builds you try on your own phone at each stage, then the release of both apps together.
The same team, the same code
The server and the web system.
What the app talks to, in TypeScript too.
API and database
A NestJS server and a PostgreSQL database that hold your data and rules for every screen.
Website and admin panel
A Next.js website, web app or admin panel on the same API, so your team and your customers see one set of data.
Hosting and fixes
The server runs on ZD Host, our own platform, with nightly backups, automatic rollback and fixes by the people who wrote it.
03 · When it fits
When to hire a React Native mobile app development company
React Native suits most business apps. Here is when it fits, with an app we built for each, and when another tool is the better choice.
React Native fits
Your users carry both phones.
And the app works with your own system.
Customers who book and follow up
Trustiva Laboratory: patients book tests and get reports in an Android and iOS app linked to the lab’s own system.
Staff who work away from the office
Trustiva Laboratory: a field app for the staff who collect samples at patients’ homes, on the same system.
Many users in several languages
RaasPaas, our Navratri pass platform: one app for Android and iOS in English, Gujarati and Hindi, beside its website.
Another tool may suit
We’ll tell you so.
A plan should start from the job, not the tool.
Games and heavy 3D
A game engine is built for that work; a business app framework is not.
Small changes to a native app
If your app is already written in Kotlin or Swift and needs only a few changes, its own language is simpler.
A team already on Flutter
If your own developers work in Flutter and will run the app, staying with it can make more sense.

How our React Native development agency works
Step 01
Brief
Tell us what you need, what you sell and where.
Step 02
Plan
We reply within two working days with one plan for your marketing and tech, priced in ₹.
Step 03
Screens and data
We draw the app’s screens and agree what the server keeps for each one, so the app and the API fit from day one.
Step 04
Stages on your phone
You try each stage on your own Android phone or iPhone. Then we release both apps and look after them and the server.
05 · Selected work
React Native apps, and the systems behind them
Two live projects on our Work page, each an app with its own server, website and admin panel. The pictures show the systems the apps talk to, with made-up data.
Build facts
Two apps, one lab system
Trustiva’s customer app and field app run on one NestJS and PostgreSQL system with 145 written requirements behind it.
Three languages, one codebase
RaasPaas: one React Native app for Android and iOS, beside a website, an installable web app and an admin portal.
One stack in both
Expo and React Native on the phone, NestJS and PostgreSQL on the server, Next.js on the web.
Hosted by the builders
Both run on ZD Host, with nightly backups and automatic deploys that roll back if a check fails.
06 · Comparison
Why choose Zero Dimensions for React Native
Most businesses compare a react native app agency with two native developers, or with a studio that builds only the app. Here is how they differ.
| What matters | Zero Dimensions | Separate native developers | App-only studio |
|---|---|---|---|
| Android and iOS | One codebase, one team | Two codebases to keep in step | Often one codebase too |
| Server, website and admin panel | Built by the same team | Usually a third supplier | Left to your web supplier |
| One change | Planned and shipped together | Made twice, plus the server | Waits for two suppliers |
| Who owns the code | You do: app, server and data | Agree it in writing | Agree it in writing |
| After launch | We host and fix app and server | Each one fixes their own part | The app only; hosting is yours |
Separate native developers make sense for a game or an app built around one phone’s own features. For most business apps, one team and one codebase cost less to build and to change.
07 · No lock-in
Yours, from the first screen.
What you can check at every stage of the build.
- The screens and the data each one needs, agreed in writing before any code.
- A build of each stage on your own Android phone or iPhone.
- One codebase for both apps, and one stack for the app, the server and the web.
- The code, the database and every login are yours.
- Hosting, nightly backups and fixes by our team, if you want them.
- Start with one app on your current system, and add more later.
08 · Cost
What does a React Native app development agency cost?
One React Native codebase usually costs less than two native apps, but the price still depends on the job. We don’t publish rates. Five things set it.
How many screens, and who uses them: customers, staff or both.
Whether the server, website and admin panel exist already or are built with the app.
What the app connects to: payments, SMS, maps, lab machines or your current software.
How many languages the app speaks.
Hosting, updates and fixes after launch.

React Native app development agency FAQs
It builds Android and iOS apps from one React Native codebase: the screens, the app’s logic, testing and release, then updates. As a react native app agency, we also build the server, website and admin panel the app works with, so one team answers for all of it.
For most business apps, yes. React Native draws the phone’s own buttons and lists, so the app looks and feels at home on Android and on iOS. Trustiva Laboratory’s two apps and RaasPaas are each one codebase for both. Games and heavy 3D are the exception.
Both make Android and iOS apps from one codebase. We choose React Native because it uses TypeScript and React, the same as our servers and websites, so one team writes the whole system. If your own developers already work in Flutter, staying with it can make sense.
Yes, we build with Expo, which still allows native code when an app needs it. On the web we are a React app development agency too: we build in Next.js, which is React, so the website, web app or admin panel comes from the same team and the same server as the app.
Often, yes. The app talks to your system through an API. If your system has none, we build one with NestJS, or we build the system and the app together, as we did for Trustiva Laboratory.
You do. For apps we build for you, you own the code of the app and the server, the database and every login, whether or not we host it.
It depends on the screens, the kinds of user, whether the server and admin panel are built too, the connections and the care after launch. We don’t publish rates. Tell us what you need and we send one plan, priced in ₹.
It depends on what the app and its system must do. We agree the screens and data first, then build in stages you can try. A large system, such as Trustiva’s lab platform with two apps, is built in phases.
In Ahmedabad, on the 4th floor of i-Hub, inside KCG Campus, Navrangpura, Monday to Saturday, 9:30 am to 6 pm. Our React Native development agency builds apps for businesses across India.
“Top” lists are often paid, so judge the work. Ask any react native agency for apps that are still running, who built the server behind them, who hosts and fixes them, and who owns the code. Ours are on our Work page.
