Which is the best mobile app development company in Kolkata?

Seven Web Tech is a mobile app development company building Android, iOS and cross-platform apps for Kolkata startups and businesses, from design to store submission.

Should I build a native app or a cross-platform app?

If your budget and timeline are tight and you need both Android and iOS, a cross-platform app built with Flutter or React Native usually makes sense. If your app depends heavily on device-specific performance, native development is the better route, and we'll tell you honestly which fits your case.

How much does mobile app development cost in Kolkata?

Cost depends on screens, backend and admin needs, real-time features, language support and platforms. We share a clear breakdown after scoping.

Will you handle Play Store and App Store submission?

Yes, we handle the entire submission process including store listing, screenshots, privacy policy requirements and responding to any review rejections until your app is live.

Do you provide app maintenance and updates after launch?

Yes, we offer ongoing maintenance for bug fixes, OS compatibility updates, and new feature additions as your app grows and user feedback comes in.

Mobile App Development in Kolkata

An App That Survives Past Launch Day

App ideas from Kolkata founders are usually practical and well-grounded. Apps fail through crashes on budget phones, slow screens or confusing onboarding, especially for users more comfortable in Bengali.

We build mobile apps for Kolkata businesses across categories, for example a retailer ordering app for a Burrabazar wholesaler, a sweet shop delivery app built for festive rushes, or a patient app for a hospital group. Each gets the right approach and language support.

Release day is only the start. We plan store listing, Bengali and English onboarding and the first round of updates with you.

How We Build Your App in Kolkata

A simple, transparent process our clients can follow at every stage

Step 1: Understanding your app idea and users

Communication

We start by understanding who your app is for, what problem it solves, and what success looks like six months after launch.

Step 2: App wireframe and platform strategy

Strategy Creation

We decide between native and cross-platform, map the core screens, and plan the backend your app will need.

App Design and Development

Our designers and developers build the UI and backend in parallel so you see real progress every week, not just at the end.

Customization

We refine screens, flows and features based on your feedback until the app feels like what you actually pictured.

Testing

We test on real Android and iOS devices, including budget phones, to catch crashes and slow screens before your users do.

Launch and Maintenance

We handle App Store and Play Store submission, then stay on for updates, bug fixes and new features post-launch.

Kolkata Industries We Build Apps For

We have hands-on experience building mobile apps for these industries:

Healthcare & Medicine

Appointment booking and patient management apps for Kolkata clinics, hospitals and diagnostic centres. Kolkata's hospitals along the EM Bypass and in Mukundapur serve patients from across Eastern India and the North-East.

E-commerce

Shopping apps with cart, checkout and order tracking for Kolkata's retail and D2C sellers. From Burrabazar wholesalers to Gariahat saree stores, Kolkata retailers are building online sales, especially around Puja season.

Real Estate

Property browsing and site-visit scheduling apps for Kolkata builders and real estate consultants. New Town, Rajarhat and the southern fringes are where most Kolkata homebuyers now compare projects.

Travel & Tourism

Booking and itinerary apps for Kolkata tour operators and travel agencies. Darjeeling, Sikkim and Puri trips make Kolkata one of the busiest markets for hill and beach holidays.

Logistics & Transport

Live tracking and delivery apps for Kolkata's transport, courier and logistics companies. Kolkata's port and trading hubs like Posta connect goods to the North-East, Bangladesh and Nepal.

Beauty & Wellness

Booking apps for Kolkata salons, spas and wellness centres with appointment reminders built in. Durga Puja and wedding seasons create booking peaks for salons across Ballygunge, Salt Lake and Behala.

What Our Clients Say

Our delivery app kept crashing with the old developer. Seven Web Tech rebuilt it and it's been stable since launch, our riders actually use it now.

They helped us cut our first version down to what actually mattered instead of building everything we asked for. Launched faster and cheaper because of it.

Got our app approved on the App Store on the first try. They handled all the paperwork and rejections we would've had no idea how to fix.
