01The practice

Four routes to an app. Which one fits depends on what it does offline and how hard marketing will push it.

What decides whether an app survives · Week one

  • A cold start that feels instantBudgeted
  • An install spike from paidLoad tested
  • Attribution wired before launchNot after
  • Works on patchy signalOffline-first
  • Store submission handledBoth stores
  • Keys and source are yoursFull ownership

02Services

What we build for Mumbai brands.

Cross-platform

React Native or Flutter, when both platforms need the same product on one budget and one team.

Native iOS and Android

Swift and Kotlin, for apps leaning on the camera, sensors, background sync or heavy offline storage.

Commerce apps

A storefront app tied to the same catalogue and stock as your website, not a second system to maintain.

App MVP

A first version in eight weeks, in front of a real user group before the roadmap hardens.

03Included

What we deliver.

01Built for the install spike

A Mumbai launch usually has paid behind it. Backend and onboarding are load-tested at campaign volume, because the spike is the test.

02Attribution wired before launch

If you cannot tell which campaign produced a retained user, the spend is guesswork. Tracking is built in, not retrofitted in month two.

03Onboarding measured, not assumed

Most installs are lost in the first ninety seconds. We instrument that path and treat drop-off there as a bug.

04One catalogue, not two

A commerce app shares stock, pricing and content with the website. Two systems diverge within a quarter and someone gets blamed.

05Tested on the phones people own

A device pass across the Android versions and screen sizes in actual use, not just the newest flagship.

06Handover with nothing withheld

Source, signing keys and both store accounts in your name. Nothing about the app depends on us staying.

04Working from Mumbai

We are a Kolkata studio. Here is what that actually means for a Mumbai client, stated plainly.

Working with Syscodes from Mumbai.

01

Compliance review as a stage

Where your copy or product needs legal or compliance sign-off, we plan that review as a scheduled stage rather than discovering it a week before launch.

02

D2C at Mumbai volumes

Sale-day traffic, warehouse feeds and returns are where most Mumbai commerce builds actually strain. We load-test for the spike, not the average.

03

Media and campaign timelines

Launch dates here are set by a campaign, not by a sprint board. We work to the date that has already been bought.

04

Your hours, your standups

IST throughout, so a 10am standup in Mumbai is a 10am standup for us. No overnight handoff and no waiting a day for an answer.

05

GST invoices in rupees

Every invoice carries our West Bengal GSTIN. IGST applies across state lines, and the input credit is claimable. No offshore paperwork.

06

Remote by default, and set up for it

Everything runs on video, in your tracker, with a staging URL you can open whenever you like. Nothing about the work depends on being in the same room.

05Process

How a Mumbai app gets shipped.

Five stages, a scope fixed in writing, and a launch worked backwards from your media date.

01ScopeWeek 1

We agree what the first release does not do. Who opens the app, on what handset, and the one job it has to finish. Then we cut the rest, because a launch date does not move for a feature list.

02DesignWeeks 2–3

Onboarding designed as carefully as the home screen. Clickable flows at real device sizes, with the first ninety seconds treated as the most important screen in the product, because it is.

A signed build on your phone every fortnight. Two-week sprints, each ending with an internal build your team installs and uses. Code lands in your repository as it is written.

Real handsets, and the backend at spike volume. A device lab pass, a battery and performance run, and a load test of the backend at the install volume your media plan predicts.

Bean-to-bar chocolate and nut-butter machinery sold to craft producers in over a hundred countries. A deep, technical catalogue that buyers could not navigate, restructured around how a chocolate maker actually shops for equipment.

Crystals, incense and sound-therapy pieces sold across the UAE and the wider Gulf. A poorly built store replaced with premium storytelling visuals and a checkout path that stops asking the customer to work.

Handmade Spanish padel bags built to go from court to office to dinner without changing. A small, considered range, so the store is written as a story rather than laid out as a catalogue.

09FAQ

App questions Mumbai clients ask us.

The ones that come up most in a first conversation.

Do you work with Mumbai clients from Kolkata?

Yes. We are a Kolkata studio working on IST, with the same hours as your team. Weekly video calls, your tracker, and a staging URL you can open whenever you like.

Can the app handle a paid install spike?

That is what we test for. The backend and the onboarding path are load-tested at the volume your media plan predicts, before the campaign runs.

Will we be able to tell which campaign works?

Yes, if attribution is wired during the build rather than added later. We treat that as part of the launch, not an afterthought.

Should the app share a catalogue with our website?

If it is a commerce app, yes. Two systems holding the same stock and pricing diverge within a quarter and someone gets blamed for it.

Native or cross-platform?

If the app leans hard on sensors, background work or heavy offline storage, native. If both platforms need the same product on one budget, React Native usually wins.

Do you handle App Store and Play submission?

Yes, including listing copy, screenshots, the data-safety declaration and review. Both accounts stay in your name.

How long does an app take?

An MVP is about eight weeks, a full product twelve to eighteen. If you have a media date, we scope backwards from it.
