App development company in India

App development
company in India.

Mobile apps for iOS and Android, designed around the people who use them.

An app development company in New Delhi, India, building native and cross-platform mobile apps for consumers, field teams and enterprises — from first concept and interface design through build, testing, app-store release and the backend behind it.

01

Consumer apps

Apps people choose to open every day: fast, obvious to use, respectful of attention. We decide with you what the app must do well and cut what it need not.

02

Field and operations apps

Apps for people who are not at a desk — sales teams, technicians, inspectors, drivers — that work offline, sync when they can, and capture what the business needs without getting in the way.

03

Enterprise and employee apps

Approvals, requests, dashboards and workflows on a phone, connected to the systems you already run and respecting the permissions you already have.

04

Product and interface design

Flows, screens and interaction designed before a line is written, tested with real people early, and refined with real usage after.

05

Backend, APIs and data

The server side that makes an app more than a screen: APIs, authentication, storage, notifications and the integrations with your other systems — on infrastructure you control.

06

Release and after

App-store submission, crash and performance monitoring, analytics that answer real questions, and the updates an app needs to stay alive.

02The practice behind it

What the same team brings.

Each of these is a practice of its own; on your project they work as one.

App Development

Mobile apps for iOS and Android, designed around the people who use them.

  • Apps for iOS and Android
  • Product and interface design
  • Build, testing and release support
The full story

A mobile app lives in someone's pocket. It has to be fast, reliable and obvious to use, or it is deleted.

We design and build mobile apps for iOS and Android, from first concept to release. We focus on the few things the app must do well, and build them properly.

02.a.6

Brand & UX

Identity, interface and experience design.

  • Brand identity
  • Interface and interaction design
  • Experience design across products and channels
The full story

How something looks and how it feels to use are part of whether it works. A clear identity and a well-designed interface earn trust before anyone reads a word.

We design brand identities, interfaces and end-to-end experiences. We start from the people who will use the product and work towards a design that is clear, consistent and yours.

02.a.3

Software Development

Custom platforms and internal tools, from specification to production.

  • Custom platforms and internal tools
  • Clear specification before build
  • Delivery through to production
The full story

Some work is too specific for off-the-shelf software. Teams patch together spreadsheets and workarounds, and the organisation carries the cost.

We build custom platforms and internal tools that fit how your organisation works. We start with a clear specification, build in stages you can see and test, and take the system through to production.

Where intelligence would help, we can build it in from the start.

Image · placeholderSecurity Testing
02.a.4

Security Testing

Penetration testing, vulnerability assessment and secure code review.

  • Penetration testing within an agreed, authorised scope
  • Vulnerability assessment
  • Secure code review
The full story

Every system has weaknesses. The question is whether you find them before someone else does.

We test your applications and infrastructure the way an attacker would, within a scope agreed with you in writing and only with your authorisation. Penetration testing probes for ways in. Vulnerability assessment maps known weaknesses across your estate. Secure code review looks for flaws in the code itself.

You receive clear findings, explained in plain language, with practical steps to fix them.

Image · placeholderAnalytics & Optimisation
02.b.6

Analytics & Optimisation

Measurement that shows what is working, and changes that act on it.

  • Measurement and tracking set-up
  • Regular analysis and reporting
  • Recommendations acted on, not just reported
The full story

Marketing data is plentiful and often unclear. Without careful measurement, it is hard to know what is working.

We set up measurement that tracks what matters, and use the swarm to read the results and propose changes. Every campaign should teach you something, and the next one should be better for it.

03How we work

Why it is different.

01

Specification first

Before anything is built, you get a written specification: what it does, what it does not, how we will know it works. Scope changes are written down too.

02

Stages you can see

Work ships in short, visible steps — a working piece every week or two — so you steer early rather than discover late.

03

You own it

Code, designs, infrastructure configuration and documentation are yours. No lock-in by hosting, licence or silence.

04

Built by a team that builds intelligence

The same engineers who build enterprise AI systems build your product. Where intelligence would help, it can be designed in from the start rather than bolted on.

The steps

  1. 01

    Discover

    We learn the business, the audience and what success means, before deciding what to build or run.

  2. 02

    Design

    Structure, interface and message, shaped with you and tested early.

  3. 03

    Build

    Engineering and creative produced in short, visible steps, with AI doing the heavy lifting and people doing the judging.

  4. 04

    Launch

    Shipped carefully, measured from day one.

  5. 05

    Improve

    We keep tuning what we built against real results.

Questions

How much does it cost to develop an app in India?

It depends on what the app does, how many platforms it runs on and what sits behind it, and anyone quoting a figure before writing the scope is guessing. We write the specification first and quote against it, including the backend and the cost of running it after launch.

Native or cross-platform — which should we choose?

Cross-platform when the app is mostly screens and data and you want one codebase for both stores; native when it leans hard on the device — camera, sensors, background work, heavy graphics — or needs the last ounce of polish. We recommend one per project and explain why.

Do we need an app at all, or would a website do?

An app earns its place when people use it repeatedly and it does something a website cannot: notifications, offline use, the camera, a daily habit. If not, a well-built web app is cheaper to run and easier to change. Our guide on choosing between a website, web app, mobile app and custom software walks through it, and we will tell you honestly which you need.

How long does app development take?

A focused app: a few months from specification to store, delivered in visible stages. Design comes first and is tested early; the build then ships working pieces every week or two rather than a single reveal at the end.

Do you build the backend as well?

Yes. Most apps are half server, and we design and build the APIs, data, authentication and integrations behind them — on infrastructure you own or choose, so the app does not depend on us to keep running.

Who owns the app and its code?

You do: source code, designs, store listings, infrastructure and documentation. We can keep maintaining it under a separate, cancellable arrangement, or hand it to your team.

Do you work with clients outside Delhi NCR?

Yes, across India and internationally. Design and build happen remotely as well as in person. Being in New Delhi helps for organisations in the region that want to sit with us for discovery and testing.

Tell us what the app has to do.

Who uses it, what they must be able to do, and what sits behind it. We come back with a specification and a plan, not a pitch.
