Cross-platform vs native app development for startups
Native vs cross-platform: which one should you build?
For most startups and business apps, cross-platform is the sensible pick. Native still wins for a few kinds of apps. Here's the quick comparison.
| Cross-platform | Native | |
|---|---|---|
| Codebases | One | Two (Swift and Kotlin) |
| Build cost | Lower | Higher |
| Time to launch | Both stores together | Often one platform first |
| Performance | Close to native for most apps | Best possible |
| Maintenance | One update for everyone | Two apps to update |
| Good for | MVPs, business, e-commerce, booking apps | Games, AR, heavy hardware use |
Flutter vs React Native for business apps
Flutter or React Native? We build in both.
Both are solid choices. The better one for you usually depends on your team and what else you're building.
Flutter
React Native
JavaScript and TypeScript · real native UI components · shares code with React websites.
Pick it when: your web team already works in React.
Cross platform app development services
Cross platform mobile app development, start to finish.
Flutter app development company · React Native app development company · hybrid app development company. Different names, same idea: one app, every platform.
01
Flutter app development
We build your app in Flutter using Dart, so one codebase runs on Android, iOS, the web and even desktop. The design is fully custom and looks the same on every device.
02
React Native app development
We build in React Native with TypeScript, so the app uses real native components on each phone. Small fixes can go out as over-the-air updates without waiting for store review.
03
Hybrid app development
Already have a web app? We package it as a mobile app for Google Play and the App Store, then add native features like push notifications, camera and offline access.
04
Multi platform app development
One codebase that covers phones, the web, Windows and macOS. Useful when your staff use desktops in the office and phones in the field.
05
Cross platform MVP development
A first version with only the features you need to test your idea, launched on both app stores. It's built on a proper foundation, so you can keep adding to it later.
06
AWS / Firebase backend
We set up the backend your app runs on. Firebase handles login and the database for simpler apps, and AWS covers APIs and hosting for bigger ones. Both come with an admin panel.
07
Cross platform eCommerce app
A shopping app with your product catalogue, cart, UPI and card payments, and order tracking. Customers get the same experience on Android and iPhone.
08
Cross platform CRM app
A mobile CRM for your sales team to manage leads, follow-ups and field visits. It works offline and syncs once the phone is back online.
09
Service aggregator app
Apps for platforms that connect customers with service providers, like home services or bookings. You get a customer app, a provider app and an admin panel to manage bookings and payouts.
10
Cross platform app migration
If you're maintaining two separate native apps or an outdated hybrid app, we move it to a single Flutter or React Native app in stages, without taking it offline.
11
Maintenance and support
After launch, we keep your app running smoothly with OS updates, framework upgrades, bug fixes and new features each month.

Share your app idea with us. We'll recommend whether Flutter or React Native suits it better and how to set up the backend.

Cross-platform apps by industry
Healthcare
Appointments · teleconsults · reports · reminders.
Fintech
Wallets · loans · KYC · secure payments.
eCommerce

For startups
Cross platform MVP development for startups
Short on time and money? A cross-platform MVP gets you on both stores at once. Launch with the core features, see what users do, then build more.
MVP development cost depends mostly on the number of screens and the backend. Most MVPs take 8 to 12 weeks.
For enterprises
Is cross-platform app development good for enterprise apps?
Yes, for most internal and customer apps. Field-force tools, approval apps and customer portals all work well. We add SSO, role-based access, offline sync and MDM support.

FAQ
Cross-platform app questions
What is cross platform app development?
Building one app that runs on both Android and iPhone from a single codebase, usually with Flutter or React Native.
Can I build an Android and iOS app with one codebase?
Yes. Most of the code is shared, with a few small platform-specific parts. You publish to Google Play and the App Store from the same project.
What is the cost of cross platform app development in India?
It depends on screens, backend and integrations. A simple MVP costs far less than a multi-app platform. We share an itemised quote after a short call.
Flutter vs React Native: which is better for business apps?
Pick React Native if your team already uses React. Pick Flutter if you want the exact same look everywhere or need a desktop app too.
Is cross platform as fast as native?
For most apps, users can't tell the difference. Native still has the edge for games, AR and very graphics-heavy apps.
Can you convert my existing native apps to cross-platform?
Yes. We migrate in stages, screen by screen, so your app stays live and updates keep going out.
Who owns the app and source code?
You do. Code, store listings and backend are all in your name.
