Mobile App Development Company Building for iOS and Android
We build cross-platform apps in Flutter and React Native, wire up the backend, push, and offline sync, and hand them to the App Store and Play Console for you. A senior team in Noida, flat INR quotes, and a written scope before any code.
Apps we have actually shipped
Start with something real. For Jai Shri Balaji Store, a grocery business in Delhi NCR, we built two mobile apps that run every day. The customer app is Flutter, one codebase for iOS and Android, with push notifications for order updates, live tracking, and Razorpay checkout. It is on the Play Store now. The delivery driver app is a second Flutter app, Android only, where drivers get orders assigned in real time, navigate with GPS, and capture proof of delivery with a photo and signature.
Those two apps, plus a web storefront and a Node.js backend, took the store from about 30 orders a day to 150 and up, without the owner drowning in messages. Both apps are built on Flutter and share a codebase, so we did not build the same thing twice. That is the kind of work this page is about: apps a real business depends on, not a prototype that dies after the demo.
Apps we build
Most of what we take on falls into four buckets. The stack and the effort change a lot between them, so it helps to know which one you are.
Storefronts, booking, content feeds, loyalty. A clean catalogue or feed, accounts, payments through Razorpay, and push notifications that bring people back. iOS and Android from one Flutter or React Native codebase.
Apps your own team uses: order taking, inventory, inspections, attendance, service tickets. These live or die on offline behaviour, because your staff will be in a basement warehouse or a rural site with no signal.
Driver and rider apps with real-time order assignment, GPS tracking, route sequencing, and proof of delivery. We shipped exactly this for Jai Shri Balaji Store and can walk you through how it works.
Wallets, payment flows, dashboards, and statements on top of a licensed provider's rails. We build the app and the integration. We do not build the core lending or banking licence platform itself, and we say so early.
The stack, and the parts people forget
For the app itself we use Flutter or React Native. Flutter is our default when the UI is custom and you want it to look identical on both platforms; it is what both Jai Shri Balaji apps run on. React Native is the better pick when you already have a React web team or lean on JavaScript libraries, since the skills and some code carry over. Either way you get true iOS and Android builds from a single codebase, not a website in a wrapper.
The app is the visible half. The other half is the backend, and that is usually where the real work is. We build the API on Node.js or Laravel, with PostgreSQL or MongoDB behind it, hosted on AWS. Push notifications are wired in so an order update or a message actually reaches the phone. Offline support means the app keeps working on the metro or in a dead-zone warehouse and syncs when the connection comes back, which for a field-ops app is not optional.
We also handle the last mile that is easy to underestimate: App Store and Play Console setup, signing, store listings, screenshots, privacy declarations, and the review back-and-forth. First submissions get bounced for small reasons, and we deal with that so your launch date does not slip by two weeks.
Why teams pick a small senior studio
We are a small studio in Noida, Sector 62, founded in 2021. Ravi Rai leads the engineering, with a project manager, a designer, and an SEO specialist. That is the whole team, and it is on purpose.
- Senior engineers on your app from day one. No junior offshore team behind an account manager, no handoff after you sign.
- Direct access to the people writing the code. You talk to the developer, not a layer that relays your questions and loses half of them.
- Both app stores handled end to end, including signing, listings, and the review process, so you are not learning Play Console under deadline.
- Flat INR quotes against a written scope, turned around in 24 hours. We can invoice in USD to a foreign parent entity if you need that.
- 56 plus projects shipped for clients in India, the USA, Canada, the UK, and the UAE, so this is not our first launch.
- Honest scoping. If you need one app and not three, or a web app instead of a native one, we will tell you before you spend.
How a build runs
Four stages, with something you can see at the end of each. You are never left wondering what is happening for three weeks.
We map the screens, the backend, the integrations, and which platforms you actually need. You get a written scope and a flat INR number within 24 hours, before any code.
The designer lays out the real screens and you sign off. In parallel we agree the API contract so the app and backend are never guessing about each other.
We build in short sprints with a working build at the end of each. You install it on your own phone and use it, so feedback is real, not theoretical.
We submit to the App Store and Play Console, handle the review, and launch. After that you get the code, the accounts, and an optional maintenance plan. No lock-in.
What it costs, and what we do not do
Pricing is a flat INR quote against a written scope, not an hourly meter. Send us the brief, we write the scope, and you get back one flat INR number, with the exact figure inside 24 hours. If you are a foreign parent company, we can invoice that entity in USD. What the number reflects is the build in front of us, not a clock running quietly in the background.
Your number depends on how many screens, how many integrations, and how many platforms you truly need. We would rather scope you down to what earns its keep than sell you three apps by default.
One honest limit: we do not build heavy native game engines or 3D-heavy titles. That is a Unity or Unreal specialism, and it is not us. We also do not build the core licensed platform behind a lending or banking product; we build the app and integrate a provider who holds that licence. If your project is one of those, we will tell you on the first call instead of taking the brief and struggling.
Frequently asked questions
Flutter or React Native, which one should I pick?
Flutter if your UI is custom and you want it to look and behave identically on iOS and Android from one codebase; it is what we used for both Jai Shri Balaji apps. React Native if you already have a React web team or depend on JavaScript libraries, because the skills and some code transfer. For most first apps we lean Flutter. On our call we pick based on your team and your UI, not a house preference.
Do you build native iOS and Android, or only cross-platform?
We build cross-platform in Flutter or React Native, which compile to real native iOS and Android apps from a single codebase. For the vast majority of business apps that is the right call: one team, one codebase, both platforms, lower cost. We are not the right studio if you specifically need fully separate Swift and Kotlin native codebases or a heavy native game engine.
Do you handle App Store and Play Console submission?
Yes, end to end. That includes developer account setup if you do not have one, app signing, store listings, screenshots, privacy and data-safety declarations, and the review back-and-forth with Apple and Google. First submissions often get bounced for small reasons, and we handle that so your launch does not slip.
How much does a mobile app cost in India?
A flat INR quote against a written scope, never an hourly meter. Send us the brief, we write the scope, and you get back one flat INR number, with the exact figure inside 24 hours. If you have a foreign parent company, we can invoice that entity in USD. What moves the number is how many screens, integrations, and platforms you actually need, not a clock.
How long does it take to build an app?
It depends on the build, so the real timeline goes in the written scope rather than a stock number here. We work in short sprints with a working build at the end of each, so you see progress the whole way instead of waiting months for a big reveal. The backend and the integrations, not the number of screens, are what move a timeline most.
Do you build the backend and API as well?
Yes, and usually we should. We build the API on Node.js or Laravel with PostgreSQL or MongoDB, hosted on AWS, plus push notifications wired in. If you already have a backend, we integrate against it and agree the API contract up front. An app without a solid backend is the most common reason a launch drags.
Can the app work offline?
Yes, and for field-ops apps it has to. We build local storage and a sync layer so the app keeps working with no signal and reconciles when the connection returns. This matters for delivery, inventory, inspection, and attendance apps where staff are in basements, warehouses, or rural areas.
Do I own the code and the store accounts?
Yes. You keep the full source code, and the App Store and Play Console accounts are registered under your business, not ours. There is no lock-in. After launch you can keep us on an optional maintenance plan or take it in-house. Your app, your accounts, your call.
