Overview

Mobile app development company: what this is, in plain words

As a mobile app development company, we default to cross-platform for a reason: one codebase, two stores, roughly half the cost of building native twice. We build with React Native (Expo) or Flutter depending on your product, and we are honest when a feature genuinely needs native code.

We handle the parts founders underestimate: authentication, offline behaviour, push notifications, payments, crash reporting, App Store and Play Store review, and the release pipeline that lets you ship updates weekly instead of quarterly.

Your app is published under your own Apple and Google developer accounts. Their fees go to the stores, and store review times are theirs, so we plan for review and cannot promise approval dates.

Who it is for

  • Startups launching a first app and needing an MVP in one quarter
  • Businesses adding a customer or field-team app to an existing service
  • Teams rescuing an app that was outsourced and never finished properly

What you get

  • A single codebase your team can maintain, with the native pieces documented
  • Store-ready builds with review checklists handled before submission
  • Over-the-air updates so fixes reach users in hours, not weeks
  • Source code, store accounts and signing keys all in your name

Signs you need it

Problems our mobile app development work fixes

If one of these sounds familiar, you are in the right place.

  1. You have an idea but no planWe turn the idea into a short list of features for a first release, so you launch sooner and learn from real users.
  2. An earlier app was never finishedWe review the code first and tell you plainly whether it is worth fixing or rebuilding.
  3. You need iOS and Android on one budgetA cross platform build with React Native or Flutter covers both stores with one team and one codebase.
  4. The app works but nobody uses itWe look at onboarding, speed and the first session, and fix the places where people drop out.

Quick answers

About cost and timing

The things people ask right after they see a price.

Prices depend on your market and scope; see the plans on this page. Payments, real-time features, an admin panel and complex back-ends all raise the cost. We scope it on a call and fix the price in writing before work starts. Flexible on scope. Firm on price.

Plan on 8 to 16 weeks from kickoff to store submission. The range depends on features, integrations and how quickly your accounts and content are ready. Store review adds time that we do not control. You get a dated plan before we start. Smaller apps land near the short end.

How we contract

Clear terms, before you spend anything

The commercial side in plain words. The full wording is in our terms, and your proposal sets the details.

  1. A written proposal comes firstScope, deliverables, milestones, price and timeline, in writing. Work starts when you accept it.
  2. The price does not moveOnce agreed, the number in the proposal is the number on the invoice. Changes to scope are quoted as a written change request and only built once you approve them.
  3. You pay by milestoneProjects are paid in milestones set in your proposal. No project is billed in full upfront. Invoices are payable within 14 days unless your agreement says otherwise.
  4. You own the workCode, designs and accounts are registered to your company from day one. We keep our own pre-existing tools and methods.
  5. No lock-inEither side can end a project with written notice, and you pay for the work done up to then. Retainers run month to month with 30 days written notice.
  6. 30 days of fixes after launchDefects in what we delivered are fixed for 30 days after launch. New features and third-party changes are quoted separately.

Not necessarily. What matters is seeing working builds often and owning the code. We are based in Noida and meet Delhi NCR clients in person; everyone else gets a weekly build on their own phone, a shared channel and calls in their time zone.

You get a working iOS and Android app, the back-end it needs, and help submitting it to both stores. That covers discovery, design, development, testing and release setup. The source code, signing keys and store accounts are in your name, with documentation so another team could continue the work.

You see a working build every week, on your own phone. We are online Monday to Saturday, 09:00 to 21:00 IST, and every message gets a reply within 12 hours. You talk to the senior engineers doing the work. Milestone payments follow agreed, visible progress. Bigger requests are planned into the next calendar.

For most apps, one cross-platform codebase is faster and cheaper to build and maintain. We pick React Native or Flutter based on your product and team. Fully native makes sense for heavy graphics or deep device features. We recommend one on the first call and explain why.

You publish under your own developer accounts, and the stores review every release. We prepare the build, screenshots and policy answers to avoid common rejections. Review times and decisions are theirs, so nobody can promise an approval date. If an app is rejected, we fix it and resubmit.

You do. The developer accounts, signing keys, source code and back-end accounts are registered to your business from day one. We work inside them as collaborators. If we part ways, nothing needs to be handed back, because nothing was ever held by us. You never need to ask us for access to your own app.

Every project includes 30 days of fixes after launch. Phones and operating systems keep changing, so most clients then agree a monthly maintenance plan for updates, upgrades and small features. It is optional, and the code is yours either way. You can also run the app alone, since nothing depends on us.

The usual risks are store rejections, features that grow mid-build and slow feedback. We agree scope in writing, show builds weekly and flag problems early. Not included unless agreed: store and hosting fees, paid tool subscriptions, marketing, and content writing. The proposal lists them. Anything outside the scope gets a price before work starts.

Yes, often. We review the code first and tell you plainly whether it is worth fixing or rebuilding. Sometimes the foundation is fine and only the last stretch is missing. Other times a restart is cheaper, and we will say so before you commit. You decide after seeing our honest review.
