05Process
How a Kolkata app gets shipped.
Five stages, a fixed scope, and a senior engineer you can meet in person.
01DefineWeek 1–2
We cut the first version to what proves the idea. A working session on who uses it, what they must be able to do, and what can wait. Most first versions are half the size the brief suggests.

Archival twentieth-century American photography printed onto coasters, mugs and canvases, each scannable to reveal the story behind the image. Rebuilt on evidence, with a dark and light mode because the imagery reads differently in each.

Alcohol-free kava and kratom tonics, positioned as the drink you have instead. Google would not show the site at all, not even for the brand name, because it was buried in duplicated AI-written content. We stripped it, rewrote it, and rebuilt on Shopify.

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.

Do you build native or cross-platform?
Usually cross-platform, because it halves the cost and most apps never need more. We say so plainly when native is the right call, and explain what it changes.
How long does an app take?
Ten to sixteen weeks for a first version, depending on how much backend sits behind it. We agree the scope and the date in writing before starting.
Can we meet at your office?
Yes. Om Tower, 7th Floor, 32 Chowringhee Road, ten minutes from Park Street metro. Scoping goes faster in person and you meet the engineers.
Who owns the code?
You do. IP is assigned on payment and the repository is yours from the first commit, not handed over at the end as a favour.
Do you handle Play Store submission?
Yes. We prepare the listing, submit, respond to review queries and stay on call through the first release. Seven days of support is included.
Do you build Android apps in Kolkata?
Yes. Android is where most Indian usage sits, so we test on the mid-range handsets your customers actually carry rather than only on a flagship.
Do you build for iOS as well?
Yes. Usually one cross-platform codebase covers both, which halves the cost. We go fully native only when the app genuinely needs it, and we say why.
What should you look for in an app development company in Kolkata?
Ask who owns the code, who is on the build day to day, and what happens to the app after launch. Ask to meet the senior lead first.
How much does mobile app development cost in Kolkata?
The build drives the number, not the city: whether one codebase serves both platforms, how much has to work offline, and how many systems the app talks to. We quote a fixed scope after a discovery call rather than a day rate. The ranges are set out in what mobile app development costs in India.
