India's startup-first mobile app development company

Xenotix Labs is a mobile app development company in India that specializes in shipping production-grade iOS and Android apps for venture-funded startups, D2C brands, and SMB platforms. We have delivered 50+ mobile apps across categories — D2C subscription commerce (Veda Milk, our Country-Delight-class dairy platform), real-time sports (Cricket Winner with WebSocket score sync at 10M+ events/day), dating (Bolcall), legal-tech (Legal Owl), insurance ops (ClaimsMitra with 114+ REST endpoints), and home-services (Cremaster, Housecare).

Most of our mobile work ships on Flutter — iOS and Android from a single Dart codebase, with platform channels for native depth where it matters (push, biometric auth, payments). For teams that already have a React/JS organization, we deliver in React Native with the same engineering rigor. When the use case demands platform-specific performance — heavy AR, high-FPS games, audio DSP — we ship native Swift/Kotlin.

Every mobile engagement at Xenotix follows the same path: Figma design system → Flutter or React Native frontend → Node.js + PostgreSQL backend → AWS infrastructure with CloudFront, S3, and managed Postgres → CI/CD via GitHub Actions → App Store + Play Store publish under our DUNS-verified developer account. We do not hand off code mid-build. The same engineers who design the architecture write the code, write the tests, and respond to incidents post-launch.

If you are a founder evaluating a mobile app development agency in India, the question is not "can they build the app" — most can. The question is whether the team that ships your MVP will still be there when you scale to 100k users and the data model bends. Xenotix is built around answering yes to that question.

Sub-services

What we ship inside mobile app development

Real engagements, real case studies — not a feature list. Each sub-service is one we have shipped to production.

Tech stack reasoning

Why our default mobile stack is Flutter + Node.js + PostgreSQL + AWS

When a founder asks us "should I build my app in Flutter or React Native?", our answer is shaped by what we have shipped. 18 of our 50+ mobile apps are Flutter, 8 are React Native, the rest are native. Flutter wins for us because the rendering engine paints the entire UI itself — no platform widget translation — which means visual parity between iOS and Android is automatic. For pre-Series-A startups burning runway, this is the difference between one mobile engineer and two.

On the backend, Node.js with PostgreSQL is our default because every single one of the 33+ products we have shipped that needed transactional integrity (subscriptions, payments, bookings, claims, fantasy contests) has stayed on this stack from MVP to scale without a rewrite. We reach for MongoDB only when the data model is genuinely document-shaped (Cricket Winner, FYZ — high-volume video/event metadata).

For background jobs, the choice is RabbitMQ vs Kafka. We use RabbitMQ for booking/order/notification flows where each job is independent (Veda Milk, Nursery Wallah, ClaimsMitra). We use Kafka when the system needs replayable event streams at high volume (Cricket Winner, FYZ, Growara). Picking wrong here is a six-month rewrite — picking right is invisible.

AWS is the deployment target for every app we ship. ECS Fargate for stateless services, RDS Postgres with Multi-AZ for primary data, S3 + CloudFront for video and asset delivery, SES for transactional email. Infrastructure-as-code via Terraform; nothing clicked in the AWS console. This means a different engineer can rebuild your environment from scratch in under an hour — including your future engineer if Xenotix ever stops being your team.

Common Questions

Frequently Asked Questions

Everything you need to know about mobile app development services

How much does it cost to build a mobile app in India in 2026?

For a Starter MVP on a single platform, ₹4-8 lakh ($5k-$10k). For a Growth build covering iOS + Android with payments, push, and an admin panel, ₹10-25 lakh ($12k-$30k). For a multi-app marketplace or sports/gaming-grade platform, ₹25-60 lakh+. We publish full tier breakdowns on this page, not behind a sales call.

How long does it take to develop a mobile app?

Starter MVPs ship in 6-10 weeks. Growth builds run 3-5 months. Scale builds with multiple apps and real-time features take 5-9 months. Timelines we quote are honored — every Xenotix engagement runs on a fixed-scope, fixed-timeline contract with weekly demos.

Should I build my app in Flutter, React Native, or native?

For most pre-Series-A startups, Flutter wins. One Dart codebase, two stores, automatic visual parity, faster iteration. Choose React Native if your org is already React-heavy and code-share with web matters. Choose native (Swift / Kotlin) only when you genuinely need platform-specific capabilities — heavy AR, high-FPS games, audio DSP, deep OS integration.

Do you handle App Store and Play Store submission?

Yes, end-to-end. We submit under our DUNS-verified Apple and Google developer accounts when needed, or under your accounts. Includes ASO research, screenshot generation, listing copy, review-response setup. Average first-time review pass: 2.4 days.

Who owns the IP and source code?

You own everything from day one — code, design files, infrastructure, AWS account credentials. We sign mutual NDA before sharing scoping documents and the engagement contract is explicit on IP transfer. No surprise licensing.

Do you provide post-launch support?

Yes. We offer monthly maintenance contracts (15-20% of build cost annually) covering OS-compat passes, crash-rate SLAs, performance budgets, and a dedicated Slack channel. 12+ shipped apps are on active maintenance with us today.

Can you sign an NDA before discussing my idea?

Yes. We sign mutual NDAs as a default before any scoping conversation. The same NDA covers any team member who joins your project. Founders share their roadmaps with us — that trust is earned by our process, not asked for.

What happens if my app needs to scale to a million users?

The stack we ship on (Flutter / Node.js / Postgres / Kafka or RabbitMQ / AWS) is the same stack we run for Cricket Winner, which sustains live IPL-match traffic. We design for the next two orders of magnitude from day one — no rewrite when you grow.
