iOS app development company in Kolkata.
We build iPhone and iPad apps from our Chowringhee Road office — Swift where it needs to be native, cross-platform where it does not — and we handle App Store submission ourselves rather than handing it back to you.
How we build iOS for Kolkata businesses.
Native, hybrid or iPad. What the app has to do on the device decides which of these is right, and we will show you the working out.
Native iOS apps
Swift and SwiftUI against the current SDK. The right answer when the app leans on the camera, background location or on-device processing, and it is written at a desk you can visit.
12–16 weeksExplore iOS app developmentHybrid iOS apps
One React Native codebase for iPhone and Android, built at our Chowringhee Road office, with Swift dropped in only where the hardware demands it.
10–14 weeksExplore hybrid app developmentiPad and universal apps
One build that behaves like an iPad app rather than a stretched phone screen. Split views, keyboard shortcuts and multitasking, reviewed in person before it ships.

Time to first value is a spec item with a number against it. That is where installs are lost, long before anyone finds a bug.

Privacy manifest, tracking permission and account deletion are settled in week one. Left to submission week, any of them forces a rework.

Om Tower on Chowringhee Road, ten minutes from Park Street metro. Walk in and see the bench — design reviews happen at a desk rather than over a screen share.

Swift is not always right. We scope and cost both routes, and a third of the apps we ship turn out not to be native at all.

What the first release does not do.
One session across a desk on Chowringhee Road to cut the list, then a fixed written scope. Native Swift and React Native are both costed, so the route is decided on requirements rather than preference.
The first ninety seconds, drawn first.
Onboarding before anything else, because that is where installs are lost. Screens follow Apple's Human Interface Guidelines, and the review happens in the room rather than over a screen share.
A TestFlight build every fortnight.
Working builds on your own phone from week five. The privacy manifest, tracking permission and account deletion go in as they are built rather than being bolted on before submission.
Through App Store review, first time.
Listing, screenshots at every required size, the privacy questionnaire, review notes and a demo account. We submit and we answer review rather than handing you a rejection to interpret.
Two weeks of cover, then your call.
Crash triage, responses to store reviews and the first read on where new users drop out. If you are in the city, that read happens over a coffee rather than in a slide deck.
Recent client work.
A sample of what we have shipped for clients across product, web and commerce. The portfolio has the rest.
Karomi Crafts
Handwoven jamdani turned into contemporary womenswear by a Kolkata label that refuses to greenwash. The store already existed; what it lacked was a path from admiring the craft to buying it.

Kampura
Award-winning organic ceremonial cacao, grown and stone-ground in Guatemala with no middlemen. A static WordPress brochure became a store, without losing a single one of the informational pages the brand had built its authority on.

Stride Ahead
Psychometric career guidance for students in grades 8 to 12, built on real assessment science rather than a marksheet. A custom platform: thirty assessments, a database of 1,500 careers, mentor programmes and school deployments.

Thread Fairy Co
Organic muslin swaddles, hooded towels and kidswear for Indian parents who read the label before they read the price. Moved off WooCommerce onto a store merchandised for gifting as much as for browsing.

Soreze Care
Silicone barrier gels that prevent bedsores, sold to families caring for elderly relatives. A category where nobody buys before they understand, so the store teaches first and sells second.

Syscodes handled our migration from WooCommerce to Shopify exceptionally well, despite having a large store with many pages and products. They ensured we didn’t lose our search rankings during the migration and, in fact, helped us grow both organic traffic and sales after the launch. Excellent work from start to finish.
Great experience working with Syscodes on our CRO-focused website redesign. They understood our goals, improved the user flow, and delivered a better design. Communication was smooth, deadlines were met, and the whole process was very professional. Would definitely work with them again.
Syscodes did an excellent job redesigning our eCommerce website. The new site looks polished, modern, and much more aligned with our brand. Professional throughout the entire process, and we’ll definitely be working with them again.
Syscodes did a great job migrating our eCommerce store from WooCommerce to Shopify and improving the overall conversion experience. The migration was handled smoothly, the new Shopify store performs much better, and the project was completed successfully.

iOS questions Kolkata clients ask us.

hello@syscodes.in+91 70034 16634Book a callThere is no price list, because scope sets the number rather than the platform. A single-purpose iPhone app and one with offline sync, background location and a backend behind it differ by an order of magnitude. We scope it after a free consultation and put the figure in writing, along with what would move it.
Yes, and more clients do than you would expect. Our office is at Om Tower on Chowringhee Road, ten minutes from Park Street metro. Scoping sessions and design reviews happen across a desk, and you can see who is actually going to write the Swift.
Ten to fourteen weeks for most first releases, with your team installing the first TestFlight build in week five. App Store review usually adds one to two weeks, which is worth putting in the plan rather than discovering at the end.
It depends on what the app asks of the phone. Camera work, background location, HealthKit, on-device processing and heavy animation point to native Swift. A product that is mostly screens, forms and data, and that needs Android too, is usually better served by one React Native codebase with Swift only where the hardware demands it. We cost both before you decide.
That is what we plan for, and we handle the submission ourselves. The items that cause avoidable rejections are settled in week one: the privacy manifest, tracking permission, account deletion, permission strings that explain themselves, and a demo account for the reviewer.
You do, both, from the first commit. The app is published under your organisation's Apple Developer account rather than ours, and the repository is yours. If you leave us, nothing about the listing has to move.
