Mobile App Development Company in Chennai
We build apps that ship. Fixed scope, weekly builds you can install on your own phone, and full source handover including the signing keys — the thing most agencies quietly keep.

Most app projects don’t fail at build. They fail at scope.
The commonest app story we hear: eighteen months, three developers, and an app that never reached the store.
It usually starts the same way — a feature list written before anyone asked what the app is actually for. Everything is version one. Nothing ships. The budget goes on features nobody uses while the one thing users needed is still in the backlog.
The fix isn’t better developers. It’s deciding what version one isn’t, in writing, before the first line of code.
Native or cross-platform?
This decision sets your cost for the life of the app. Most Chennai businesses are better served by cross-platform — we’ll tell you when you’re not.
| Cross-platform (Flutter / React Native) | Native (Swift / Kotlin) | |
|---|---|---|
| Typical cost | ₹4,50,000–9,00,000 | ₹8,00,000+ per platform |
| Time to launch | 12–18 weeks | 16–24 weeks per platform |
| One codebase, both stores | Yes | No — two teams, two builds |
| Performance | Excellent for most apps | Best |
| Heavy device features | Good — camera, GPS, notifications | Best — AR, ML, background audio |
| Right when | Standard business app, both platforms, sane budget | Games, AR, heavy processing, or platform-specific UX matters |
| Wrong when | You need bleeding-edge OS features on day one | Budget only stretches to one platform — you’ll orphan half your users |
What every app build includes
Store submission included. It’s where a surprising number of projects stall.
Get a fixed quoteWhat version one is, and explicitly what it isn’t. Signed by both sides.
Screens designed and approved before build, following iOS and Android conventions rather than fighting them.
Built by us or integrated with what you have. Documented either way.
TestFlight and Firebase App Distribution. You use it on your own phone from week four.
App Store and Play Store listings, screenshots, privacy declarations, and handling rejections.
Configured before launch, not bolted on when something breaks.
Source code, store accounts in your name, and the keystore. Without those you cannot publish an update without us.
The keystore question
Ask any agency quoting you: “who holds the Android keystore and the Apple signing certificate?”
If the answer is “we do, don’t worry about it”, walk away. Those keys are what let you publish updates. Without them you cannot update your own app — you would have to publish a brand new listing and lose every review and install.
Ours go in your accounts from day one, and we walk you through backing them up. It costs us nothing and it’s the single most common way app clients get trapped.
Sixteen weeks, seen weekly
Scope and fixed quote
What version one does, what it deliberately doesn’t, which platforms, and what the backend needs to handle. Price fixed against it.
Design
Every screen, following platform conventions. Approved before development starts.
Build
Two-week sprints. From week four you get an installable build on your own phone after every sprint.
Testing
Real devices, not just simulators. Older Android handsets included — that’s most of the Indian market.
Store submission and handover
Listings, screenshots, privacy declarations, review responses. Then full handover including keys.
What an app costs
Apps are the most under-quoted service in this market, usually by leaving out backend, store submission and testing. These figures include all three.
MVP
One core job, done well. For validating an idea before scaling it.
- Cross-platform, both stores
- Up to 8 screens
- Basic backend and auth
- Store submission included
- 12–14 week delivery
Business app
Full product with accounts, payments and admin.
- Everything in MVP
- Payments (Razorpay / in-app)
- Push notifications
- Admin dashboard
- Analytics and crash reporting
- 16–20 week delivery
Platform
Multi-role apps, ERP integration or heavy device features.
- Native where it’s justified
- Multiple user roles
- ERP / CRM integration
- Offline-first sync
- 20–28 week delivery
Apple charges $99/year and Google a one-off $25 for developer accounts, paid directly by you. Server hosting is separate. Full pricing →
Eighteen months in, nothing shipped
A Chennai business came to us with an app that had been in development for eighteen months across two previous teams. The feature list ran to sixty items and none were finished. We cut version one to four screens covering the single job users actually needed, shipped it in fourteen weeks, then added features based on what people used rather than what had been assumed.
When you shouldn’t build an app
We turn down more app enquiries than we take. Usually for one of these reasons.
A website would do it
If people use it once a month, they won’t install an app for it. A fast mobile website costs a fifth as much and needs no download.
No budget for year two
Apps need maintenance — OS updates break things annually. Budget roughly 15–20% of build cost per year or don’t start.
No one owns it internally
Apps need someone answering reviews and deciding what ships next. Without that they go stale within a year.
Straight answers
How much does it cost to build an app in Chennai?
An MVP covering one core job starts at ₹4,50,000. A full business app with payments, notifications and an admin dashboard is ₹8,50,000 upwards. Multi-role platforms with ERP integration start around ₹15,00,000. Quotes well below these usually exclude the backend, store submission or real-device testing — check what’s in scope before comparing numbers.
How long does it take?
Twelve to fourteen weeks for an MVP, sixteen to twenty for a full business app, twenty to twenty-eight for a platform. From week four you get an installable build after every sprint, so you’re using it long before launch rather than waiting for a demo.
Flutter, React Native or native?
Cross-platform for most business apps — one codebase, both stores, and performance that’s indistinguishable for anything that isn’t a game. Native when you need AR, heavy on-device processing, or platform-specific UX that genuinely matters. If your budget only covers one native platform, cross-platform is almost always the better call.
Do I own the app and the signing keys?
Yes, and the keys matter more than people realise. Store accounts are created in your name from day one, and the Android keystore and Apple signing certificate live in your accounts. Without those you cannot publish an update — you’d have to launch a new listing and lose every review and install. Any agency holding them is holding you.
Do you handle App Store and Play Store submission?
Yes, included. Listings, screenshots, descriptions, privacy declarations and data-safety forms. If a submission gets rejected we handle the response — first-time rejections are common and usually about privacy disclosures rather than the app itself.
What happens after launch?
Thirty days of support is included for bugs. After that, apps need ongoing maintenance in a way websites don’t: iOS and Android ship breaking changes annually, and an unmaintained app eventually stops installing on new devices. Budget roughly 15–20% of the build cost per year, whether with us or anyone else.
Tell us what the app is for
Not the feature list — the job it does. We’ll come back with a scope, a fixed price, and an honest view on whether you need an app at all.
