Ask AI about this service

We design, build, and maintain mobile apps that work on poor networks, integrate with the systems behind them, and survive years of OS updates. Native or cross-platform is chosen on the merits of your product, not our preference.

Backend and integration

APIs, push, analytics, and links into ERP, CRM, and device data.

Release and operations

Store submission, crash monitoring, and an upgrade path for each OS release.

Typical apps.

From customer-facing products to tools for people working away from a desk.

Field service

Inspections, checklists, and work orders that sync when connectivity returns.

Industrial · Utilities

Customer apps

Accounts, orders, and support in one app, backed by your systems.

Enterprise · Retail

Companion apps

Control and monitor connected devices from a phone.

IoT · Hardware

A tappable prototype on a phone in 7 days.

From the day you engage us, not from a kickoff weeks later. Every milestone is a result you can see.

  1. Day 3

    User flows and platform approach agreed

  2. Day 7

    Interactive prototype on real devices

  3. Day 45

    Store-ready first release with analytics and crash reporting

  • Fixed scope

    Scope, price, and milestones are agreed before work starts.

  • No surprises

    Weekly demos and plain-language status. Changes are priced before they are built.

  • Compliance from day one

    Privacy permissions, secure storage, and store-policy checks are handled in the first sprint, not at submission.

  • You own the IP

    Code, models, and documentation transfer to you on successful handover.

Know the price, the date,
and the exit before we start.

Fixed-scope project. A defined deliverable at a fixed price and date. Payment is released as each milestone is accepted. The same terms are written into every statement of work for mobile app development, so there is nothing to discover later.

  • Quote Within 5 working days Price per milestone, dates, and named architect
  • Priced One price per milestone Third-party costs listed separately, at cost. Invoiced in USD for international clients
  • Paid On accepted working software Not on calendar dates or hours logged
  • Changes Written and priced first Cost and date impact before work starts
01 · The payment ledger

You fund accepted work, never a promise.

Drag to move through the engagement. Money is released only as each gate is accepted, so what you have paid never runs ahead of what you can use.

02 · The stress test

When something goes wrong, who pays?

Every project meets surprises. What matters is who carries them. Pick one and compare how three commercial models respond.

Time & materials

The hours keep running while the team investigates. You pay for the surprise.

Conventional fixed price

A change request is raised, usually priced at a premium and argued over.

Our contract

We verified it before quoting, and the risk register held an allowance. Any overrun beyond it is ours.

03 · The anatomy of the price

One price, built in the open.

The proposal itemises every feature or milestone, names its assumptions, and keeps a risk register with allowances. Allowances you never use are not billed.

What moves the price
  • Number of user journeys and screens
  • Integrations and third-party SDKs
  • Platforms and devices supported
  • Security and compliance needs
Assumptions written into the SOW (open one to see what happens if it is false)
Designs and user flows are signed off at the end of sprint one.

If falseLate changes to signed-off flows are a costed change request.

Third-party APIs and SDKs are verified before we quote.

If falseIf one behaves differently than documented, the overrun is ours, not yours.

Acceptance criteria per feature are written into the SOW.

If falseEach feature is accepted against its own criteria, not a general impression.

Billed at cost, never marked up
  • Cloud hosting
  • Store and developer-account fees
  • Third-party licences

Invoiced in USD for international clients, with the currency fixed in the SOW. You own it. Code, models, documents, and credentials transfer on payment.

Technology

Built on a production-grade stack.

We pick tools proven in production and maintainable over long lifecycles - not whatever is trending. These are a few we reach for here; explore the full stack behind our engineering.

Straight answers on timelines, price, risk, and ownership, the same terms that appear in every proposal.

01What is Mobile App Development?

Mobile app development for iOS and Android: product design, native and cross-platform engineering, backend integration, and long-term support.

02How quickly does Mobile App Development deliver a first result?

A tappable prototype on a phone in 7 days. Typical milestones are Day 3: user flows and platform approach agreed; Day 7: interactive prototype on real devices; Day 45: store-ready first release with analytics and crash reporting. Exact dates are written into the statement of work before you commit.

03How is Mobile App Development priced?

Fixed-scope project: one price per milestone, with a first-release date, itemised in a statement of work within five working days of scoping. Payment is released as each milestone is accepted against written criteria. Cloud hosting, licences, and model usage are passed through at cost. International clients are invoiced in USD. The main price drivers are number of user journeys and screens, integrations and third-party SDKs, platforms and devices supported, security and compliance needs.

04What happens if the scope changes or the work overruns?

The price stays fixed. A change to scope is quoted in writing, with its cost and date impact, and starts only after you approve it. If our own estimate was wrong, the overrun is ours, not yours. You see the budget position against milestones at every demo.

05Who owns the code, models, and documentation?

You do. Code, models, and documentation transfer to you on successful handover. Code, architecture documents, deployment scripts, and credentials transfer on payment, with no licence back.

06How are security and compliance handled?

Privacy permissions, secure storage, and store-policy checks are handled in the first sprint, not at submission.

07Do you work with clients outside India?

Yes. We are based in Noida and work with clients around the world, delivering remotely. Calls and demos are scheduled in your time zone, proposals and contracts are in English, international clients are invoiced in USD, and every engagement follows the same fixed-scope terms regardless of where you are.

08When would you decline to fix a price?

If the scope is not yet defined, we do not guess a number. We propose a short, time-boxed discovery with its own fixed price, then quote the build.
