Cross-Platform App Development in India
Cross-platform app development means building one codebase that runs on both Android and iOS, using frameworks like Flutter or React Native, so you launch on the Play Store and App Store without paying to build two separate apps. I am Amit Kumar, CEH and CRTA certified, based in Hisar, Haryana, and I build cross-platform apps for clients across India. This approach usually saves 30 to 40 percent versus native and gets you to both stores faster, which is why most startups choose it.

What Cross-Platform Development Means
Normally, to be on both Android and iOS you would build two separate apps, one in Kotlin and one in Swift, which means paying for the same work twice. Cross-platform development solves this by using a single codebase that compiles to both platforms. You write the app once with Flutter or React Native, and it runs as a real installable app on both the Play Store and the App Store. Unlike a plain website wrapped in an app, modern cross-platform apps render native-quality interfaces and can access the camera, GPS, notifications, payments and offline storage. The result is one team, one codebase, one set of updates, and two app stores covered. For most Indian startups and businesses, this is the fastest and most cost-effective way to launch, because you reach every smartphone user without doubling your build budget. I handle the full app: the shared codebase, the backend, payments, testing on both platforms, and publishing to both stores.
Cross-Platform Apps I Build
I build cross-platform apps across many categories. Startup MVPs that need to test an idea on both Android and iOS quickly and cheaply. Commerce and delivery apps with catalogues, cart, Razorpay or UPI checkout and order tracking. Booking and service apps for clinics, salons, gyms and tutors. Education apps that stream and protect lessons, which I know well from running my academy. Social and community apps with feeds, chat and notifications. Business dashboards and internal tools that staff use on whatever phone they own. Because one codebase serves both platforms, you get consistent design and behaviour everywhere, and future updates ship to both stores at once. I begin by defining the core screens and the smallest useful first version, so you launch on both platforms, gather real feedback, and grow from there. This keeps your upfront cost low while still reaching the entire market.
Flutter, React Native and My Stack
I build cross-platform apps in Flutter (Dart) or React Native (JavaScript), choosing based on your project. Flutter gives beautiful, consistent UI and excellent performance, and is Google-backed. React Native is JavaScript-based, has a huge ecosystem, and is a great fit if your team already knows web technologies. For the backend I use Node.js or Firebase with a proper database. Payments go through Razorpay and UPI, the methods Indian users trust. Push notifications run on Firebase Cloud Messaging, and login can be phone OTP, Google or email. Being security certified, I encrypt sensitive data, secure your API tokens, and follow both stores' rules so the app passes review. A key strength of cross-platform is that I test and ship to Android and iOS from one codebase, so bug fixes and new features reach both platforms together, which keeps long-term maintenance cheaper than juggling two separate native apps.
Cross-Platform vs Native: The Honest Comparison
Here is the trade-off, stated plainly. Cross-platform (Flutter, React Native) gives you both Android and iOS from one codebase, cutting build cost by roughly 30 to 40 percent and getting you to both stores faster, with a single team maintaining one app. The cost is a small dip in raw performance and occasional limits with very device-specific features, though for the vast majority of apps this difference is invisible to users. Native (separate Kotlin and Swift apps) gives maximum performance and deepest access to platform features, but you pay to build and maintain two codebases. My honest rule: for startups, MVPs, business apps, e-commerce and most everyday apps, cross-platform is the smart choice, and it is what I recommend to most clients. Choose native only if you are building something performance-critical like a heavy game, an AR app, or something that leans hard on cutting-edge device hardware. I will tell you honestly which category your app falls into.
My Process From Idea to Both App Stores
My process is clear and paced. We start with a discovery call to list screens and features and agree what version one must do. I send a fixed scope and quote. I design the screens and get your sign-off before coding. Then I build the shared codebase in short cycles, sending you a testable app for both Android and iOS every week or two, so you see progress early. I test on real Android and iPhone devices, harden security and fix bugs. Then I publish to both stores: I set up your Google Play account (one-time 25 USD) and Apple Developer account (99 USD per year), prepare both listings, and manage the reviews until your app is live on both. After launch I stay available for updates that ship to both platforms at once. You get the full source code, so you own your app completely. You can reach me directly on WhatsApp at 75175 72000 throughout.
Cross-Platform App Pricing in India
Because one codebase covers both platforms, cross-platform is cost-effective. A simple app for both Android and iOS with a few screens, login and basic content starts around ₹60,000. A mid-range app with payments, accounts, notifications and an admin panel typically runs ₹1,10,000 to ₹1,80,000 for both stores. A complex app with real-time features, maps and multiple roles can reach ₹2,50,000. Compare that with native, where building the same app twice would cost significantly more. On top of the build, budget for the one-time Google Play fee (25 USD, about ₹2,000), the yearly Apple fee (99 USD, about ₹8,300) if you want iOS, and backend hosting of ₹500 to ₹3,000 a month. I give a fixed quote after the scope call, and I can phase the build so you launch a core app first and add features as you grow.
Why Build Cross-Platform With Me
You work directly with me, the developer who writes your code. I am CEH and CRTA certified, so security is built into your app from the start, which matters for anything handling payments or personal data. I know the Indian market: UPI, Razorpay, OTP login, low-network handling and budget devices are things I design for by default. Cross-platform is where I save clients the most money, because one codebase covers both stores and future updates ship once. My pricing is fixed and honest, with no hidden charges, and I explain the native-versus-cross-platform trade-off in plain language instead of pushing the pricier option. You get the full source code and documentation, so you own your app outright. I am based in Hisar, Haryana, and work with clients across India over calls and WhatsApp. If you want to reach both app stores affordably, message me at 75175 72000 for a free chat about your idea.

Frequently Asked Questions
How much does a cross-platform app cost in India?
A simple cross-platform app for both Android and iOS starts around ₹60,000, a mid-range app with payments and an admin panel runs ₹1,10,000 to ₹1,80,000, and a complex app can reach ₹2,50,000. Because one codebase covers both stores, it costs 30 to 40 percent less than building two native apps. I quote a fixed price after a scope call.
How long does cross-platform app development take?
A simple cross-platform app takes about 4 to 6 weeks for both platforms. A mid-range app with payments and a backend usually takes 7 to 11 weeks. Complex apps take 3 months or more. Because it is one codebase, you get both Android and iOS in roughly the time a single native app would take.
Cross-platform vs native: which is better for my app?
For startups, MVPs, business apps and most everyday apps, cross-platform is better because one codebase covers both stores and cuts cost 30 to 40 percent, with performance users won't notice a difference in. Choose native only for performance-heavy apps like games, AR or hardware-intensive products. I will tell you honestly which category your app fits.
Should I use Flutter or React Native?
Both are excellent. Flutter (Dart) gives beautiful, consistent UI and strong performance and is Google-backed. React Native (JavaScript) has a huge ecosystem and suits teams that already know web technologies. I pick based on your project's needs, your existing team, and the specific features you want. For most business apps, either works very well.
Does a cross-platform app feel as good as a native app?
For the vast majority of apps, yes. Modern Flutter and React Native render native-quality interfaces and access the camera, GPS, payments and notifications directly. The small performance gap only shows up in very demanding cases like heavy games or AR. For commerce, booking, education and business apps, users cannot tell the difference.
Do you publish to both the Play Store and App Store?
Yes. I set up your Google Play account (one-time 25 USD) and Apple Developer account (99 USD per year), prepare both store listings, and manage both reviews until your app is live on both. Since it is one codebase, future updates ship to both stores together, which keeps maintenance simpler and cheaper.
Kya ek hi app Android aur iPhone dono par chalega?
Haan, bilkul. Cross-platform development mein main ek hi codebase Flutter ya React Native mein banata hoon jo Play Store aur App Store dono par asli app ki tarah chalta hai. Isse do alag apps banane ki zaroorat nahi padti, aur aapki cost 30 se 40 percent tak kam ho jaati hai. Dono stores par ek saath launch ho jaata hai.
Can you add UPI and Razorpay payments to a cross-platform app?
Yes. I integrate Razorpay and UPI, the payment methods Indian users trust most, into your cross-platform app, so the checkout works identically on both Android and iOS. I handle the full flow, order confirmation and secure transaction handling, plus wallets, cards and net banking through Razorpay.
Will future updates cost double for two platforms?
No, that is a key advantage. Because there is one shared codebase, new features and bug fixes are built once and ship to both the Play Store and App Store together. This makes long-term maintenance noticeably cheaper than keeping two separate native apps in sync, which is a big reason startups choose cross-platform.
Do I get the source code and post-launch support?
Yes. You receive the complete source code and documentation, so you own your app fully and are never locked to me. After launch I stay available for updates, new features and maintenance across both platforms. You can reach me directly on WhatsApp at 75175 72000, not a call centre.
