Best Mobile App Development Company in India for iOS, Android & Cross-Platform Apps

Innovative AI Solutions is a mobile app development company that designs, builds and ships Android, iOS, Flutter and React Native apps for businesses across India — covering UI/UX, backend, APIs, AI integration and app store deployment under one team. We're based in Delhi NCR and work in person with local businesses, alongside remote clients across India and international markets, taking apps from an initial idea through to a live product on the Play Store and App Store.

Mobile app development services in Delhi

A mobile app development company designs the interface, builds the app for Android and/or iOS, connects it to a backend and set of APIs, tests it on real devices, and manages submission to the app stores. As a mobile application development company in Delhi, we handle each of those stages in-house rather than outsourcing pieces of the build, so the app, its backend and its deployment stay consistent from the first sprint to launch.

We take on projects at any stage — a first-time founder with a rough idea, a business that needs to digitize an existing process into an app, or a team that already has an app and needs it rebuilt, extended or stabilized. Depending on what the project needs, work is scoped as native Android and iOS development, a single Flutter codebase, or a React Native development build, with the recommendation based on your timeline, budget and feature list rather than a default technology preference.

Every engagement starts with a discovery conversation, not a quote — we go through what the app needs to do, who it's for, and which parts of the idea matter for a first release versus a later update. That scope becomes the basis for wireframes, a platform recommendation, and a fixed-feature build plan, so you know what you're getting and roughly when, before any development work begins.

Android, iOS, Flutter & React Native app development

Yes — we build both Android and iOS apps, either as two native codebases or as one cross-platform codebase with Flutter or React Native, depending on what fits your app and budget.

Android App Development

Kotlin-based Android development for apps that need deep integration with Android-specific hardware, background services, or performance that a cross-platform layer can't guarantee. As an Android app development company in Delhi, we build for the current Play Store guidelines and target the device range your users actually carry.

iOS App Development

Swift-based iOS development following Apple's Human Interface Guidelines, for apps that need tight integration with iOS frameworks, camera/ARKit features, or App Store distribution requirements that benefit from native tooling. As an iOS app development company in Delhi, we also manage certificates, provisioning and App Store Connect setup.

Flutter App Development

One Dart codebase compiled to native Android and iOS apps, which is usually the right call for MVPs, business tools and apps without heavy platform-specific requirements. As a Flutter app development company in Delhi, this is our default recommendation whenever a client needs both platforms without doubling the build effort.

React Native App Development

A JavaScript/TypeScript codebase rendering real native UI components, a strong fit if your team already works in React or your product needs to share logic with an existing React web app. See our dedicated React Native development services page for the full breakdown of that service.

Cross platform app development or native — which fits your app?

Cross-platform app development (Flutter or React Native) gets you to both app stores from one codebase and is the more cost-effective path for most business apps. Native development is worth the extra cost when the app is performance-critical, graphics-heavy, or depends on hardware and OS features a cross-platform layer doesn't expose cleanly.

In practice, most MVPs, internal tools, booking apps and content-driven apps are better served by cross-platform app development — a single codebase means one team builds and maintains one product instead of two, which lowers both the initial cost and the ongoing maintenance bill. Apps built around continuous camera processing, complex animation, background audio, or deep hardware access (fitness trackers, AR features, POS/payment hardware) tend to perform and feel better as native builds. We scope this during the discovery call rather than assuming an answer up front, and we're equally set up to deliver either path.

What goes into building the app

Beyond the app screens themselves, a production mobile app needs a design system, a backend, a set of APIs, and the plumbing for accounts, payments and notifications — all of which we build as part of the engagement.

Mobile UI/UX design — wireframes and high-fidelity screens designed around each platform's conventions, reviewed with you before development starts so there are no surprises at build time.

Mobile backend development — the server-side application, database design and business logic that powers the app, built in Node.js, Python/FastAPI or another stack that fits your team's needs.

API development & integration — REST or GraphQL API development for the app's own backend, plus integration with third-party services like maps, SMS, CRMs or payment gateways.

Authentication & user management — sign-up/login flows including email, phone OTP and social login, role-based access where an app needs different permission levels (customer, staff, admin).

Payment integration — Razorpay, Stripe or similar gateways wired into checkout, subscriptions or in-app purchases, with the transaction and refund logic handled server-side.

Push notifications — transactional and marketing notifications via Firebase Cloud Messaging, including topic-based segmentation so users only get notifications relevant to them.

Firebase integration — Firebase Authentication, Firestore, Cloud Messaging, Crashlytics and Analytics wired in where they're the right fit, giving the app real-time data sync and crash visibility out of the box.

AI integration in mobile apps — chat assistants, recommendation logic, document/image processing or voice interfaces added to the app in partnership with our AI & Automation team.

Mobile application development services by use case

Most projects we take on fall into a handful of patterns. Here's what mobile app developers on our team typically build within each:

Ecommerce mobile apps

Product catalogs, cart and checkout, order tracking and payment integration, usually paired with push notifications for order updates and offers.

EcommerceRetail

Booking apps

Appointment, table or service booking flows with calendar/slot logic, reminders, and payment or deposit collection at the time of booking.

ServicesHospitality

Education & EdTech apps

Course content, video lessons, quizzes and progress tracking, often with an AI tutor or doubt-solving assistant built into the app.

Education

Workforce & field apps

Internal tools for field teams — attendance, GPS check-in, task assignment and reporting, built for reliable use with patchy connectivity.

ManufacturingLogistics

Business & enterprise apps

Internal dashboards, approval workflows and operations tools that connect to your existing systems rather than replace them.

Enterprise

MVP mobile app development

A focused first version built around the two or three features that prove the idea, so you can get in front of real users and investors quickly, then expand from there.

Startups

Testing, app store deployment and ongoing support

Yes — we handle both Play Store and App Store deployment as part of every engagement, along with the QA and maintenance work that comes before and after launch.

Mobile app testing & QA

Functional testing across real Android and iOS devices, plus checks on slower networks and older OS versions so the app doesn't just work on the developer's phone.

App Store & Google Play deployment

Store listing setup, screenshots, privacy disclosures, and submission — including responding to review feedback until the app is approved and live.

Mobile app maintenance & support

Post-launch support for OS updates, bug fixes, dependency upgrades and new feature requests, so the app keeps working as Android and iOS evolve.

Security & scalability

Secure authentication, encrypted data in transit, and a backend architecture designed to handle growth in users without a rebuild.

Mobile app development process

1

Scope & platform choice

Define the core features for launch and decide cross-platform vs. native based on your requirements and budget.

2

UI/UX design

Design screens reviewed with you before development, following each platform's design conventions.

3

Development & backend

Build the app and its backend API in parallel, with regular builds you can test on a real device.

4

QA & store submission

Test across devices, then handle App Store and Play Store submission and review feedback.

How much does mobile app development cost in Delhi?

There's no fixed price list — cost depends on how many screens the app has, whether it's native or cross-platform, and how much backend and integration work it needs. An MVP with a handful of screens costs meaningfully less than a full-featured production app with custom backend and multiple integrations, and a short scoping call gives you an accurate range for your specific project.

Number of screens and feature complexity — more screens and custom user flows mean more design, development and QA time.

Android, iOS, or both platforms — a single-platform launch costs less than shipping to both stores on day one.

Flutter, React Native, or fully native development — cross-platform generally costs less than building two separate native apps.

Depth of custom UI/UX design — a highly bespoke visual design takes longer than working from a clean, standard component system.

Backend and database complexity — simple CRUD screens cost less than an app with real-time data, complex permissions or heavy business logic.

Number and complexity of API integrations — each external system the app talks to adds integration and testing work.

Payment gateway integration — checkout, subscriptions and refund handling add scope beyond a basic content app.

Push notifications and Firebase services — straightforward to add, but segmentation and triggers add some setup time.

Third-party integrations — maps, SMS, CRM or logistics APIs each bring their own documentation and edge cases to handle.

AI features, if any — a chatbot or recommendation engine adds meaningful scope beyond a standard CRUD app.

QA scope and device coverage — testing across more devices and OS versions takes longer than testing on one reference device.

Post-launch maintenance — ongoing support for OS updates and new features is usually quoted separately from the initial build.

Because of how many variables affect the final number, we don't publish a fixed price list — it would either be misleadingly low for a real project or overpriced for a simple one. A short scoping call is enough for us to size the project accurately and put a number against it.

How long does it take to build a mobile app?

An MVP with a focused feature set typically takes a few weeks to a couple of months. A full production app with a custom backend, multiple integrations and thorough QA takes longer, usually a few months from kickoff to store submission.

Timeline is driven by the same factors as cost — screen count, platform choice, and how much backend/API work is involved. Cross-platform builds (Flutter or React Native) are generally faster to reach both app stores than building two separate native apps in parallel, since there's one codebase to design, build and test rather than two. We give a concrete timeline once the feature scope is locked during the discovery phase.

A rough guide: a lean MVP with 6–10 screens, basic authentication and a simple backend is usually the fastest path to a live app. A mid-size app with payments, notifications and several third-party integrations takes longer to design and QA properly. A larger enterprise or multi-role app — with admin dashboards, complex permissions and multiple integrated systems — takes the longest, since more of the build depends on backend work that has to be right before the app layer can be finished and tested.

Mobile app developers in Delhi NCR — and beyond

We're based in Delhi and work in person with businesses across Delhi NCR, including Noida, Greater Noida, Gurugram and Ghaziabad, alongside remote engagements with clients further afield.

Being based in Delhi means in-person discovery sessions, design reviews and demos are straightforward for local clients, which tends to speed up decision-making during a build. As a mobile application development company in Delhi NCR, we also work with founders and teams who prefer to run the entire project remotely — the process and deliverables don't change, only how the check-ins happen.

We work with businesses and teams across India and international markets through remote collaboration, using the same scoping, design-review and testing process regardless of where the client is based. If you're outside Delhi NCR, project communication runs through video calls, shared design files and a staging build you can test on your own device at each milestone.

The mix of local and remote clients shapes how we scope projects: a founder in Gurugram can sit through a design review in person, while a client abroad gets the same review as a recorded walkthrough with comments logged against each screen. Either way, you see working builds throughout the project rather than a single reveal at the end, which is what makes remote collaboration practical for something as detail-heavy as a mobile app.

Shiv Lal Manpower — a real, live mobile app we built

Rather than list generic claims, here's an actual project: a workforce management app for Shiv Lal Manpower, a staffing and manpower services business, live on the Google Play Store today.

The problem — a manpower and staffing business needed a reliable way for field employees to mark attendance, request leave and access payslips from their phone, replacing manual, paper-based HR processes that don't hold up across scattered job sites.

The build — a React Native (Expo) app for Android and iOS with GPS- and selfie-verified attendance check-in/out, attendance history, leave requests and leave balance, payslip access, push notifications and employee profile management, built for reliable use out in the field.

Technology — React Native with Expo, React Navigation and Redux Toolkit on the mobile side, with Expo's camera and location modules powering the selfie- and GPS-verified check-in flow.

Status — live and published on the Google Play Store under the package in.shivlal.manpower.

Frequently asked questions

What does a mobile app development company do?
A mobile app development company designs the app's UI/UX, builds it for Android and/or iOS, develops the backend and APIs behind it, tests it on real devices, and manages submission to the Play Store and App Store — then supports it after launch.
How much does mobile app development cost in Delhi?
Cost depends on the number of screens, platform choice (native vs. Flutter/React Native), backend complexity and integrations like payments or AI. A scoping call gives an accurate estimate for your specific project.
How long does it take to build a mobile app?
An MVP typically takes a few weeks to a couple of months. A full production app with a custom backend and multiple integrations usually takes a few months from kickoff to store submission.
Can you develop both Android and iOS apps?
Yes — either as two native codebases (Kotlin for Android, Swift for iOS) or as one cross-platform codebase using Flutter or React Native, depending on what fits your project.
Flutter vs React Native — which is better?
Both render native-quality UI from a single codebase. Flutter tends to suit teams without an existing React codebase and apps needing highly custom UI; React Native is a natural fit if your team or web product already uses React. We recommend based on your specific situation.
Should I choose a native app or cross-platform?
Cross-platform (Flutter or React Native) is right for most business apps and MVPs since it covers both stores from one codebase. Native makes sense for performance-critical or deeply platform-specific apps — we'll recommend based on your requirements.
Can you build the backend for a mobile app?
Yes — backend development, database design and API development are part of our mobile app development services, built alongside the app rather than handed off to a separate vendor.
Can you integrate AI into a mobile app?
Yes — a chat assistant, recommendation engine, document/image processing or voice interface can be built into the app, working with our AI & Automation team.
Do you handle Play Store and App Store deployment?
Yes — we manage store listing setup and the submission process, and respond to review feedback until the app is approved and live.
Do you provide support after the app launches?
Yes — ongoing support for OS updates, bug fixes and new feature development is available after launch, on a support plan sized to your app.
Is Innovative AI Solutions a mobile app development company in Delhi NCR?
Yes — we're based in Delhi and work in person with businesses across Delhi NCR, including Noida, Greater Noida, Gurugram and Ghaziabad, alongside remote clients across India and international markets.
Do you work with clients outside India?
Yes — we work with businesses and teams across India and international markets through remote collaboration, using the same design, development and testing process as in-person projects.
Can you add payment and push notifications to my app?
Yes — payment gateway integration (Razorpay, Stripe and similar) and push notifications via Firebase Cloud Messaging are both standard parts of our mobile app builds.
I only have a rough idea, not a finished spec — can you still help?
Yes — the discovery phase exists for exactly this. We work with you to turn a rough idea into a scoped feature list and wireframes before any development starts, so the build plan reflects what actually matters for launch.
Can you take over or extend an app another agency built?
Yes — we regularly pick up existing Android, iOS, Flutter and React Native codebases to fix bugs, add features or rebuild parts that have become hard to maintain.
