Mobile app development that people keep on their home screen

Android and iOS mobile app development using React Native and modern cross-platform stacks — one codebase, both stores. From customer-facing apps to delivery, booking, and internal staff apps for businesses across West Bengal and India.

We're a product-minded app studio in Bardhaman (Burdwan), West Bengal — shipping Android and iOS apps for founders and businesses across Durgapur, Asansol, Kolkata, and Siliguri, and for startups in the US, UK, Europe, Australia, and the Middle East. One React Native codebase, both stores, native-quality feel — designed to be opened tomorrow, not just downloaded today.

One codebase · two stores

Write it once. Ship it everywhere it matters.

Building Android and iOS separately means paying for the same app twice. We build on React Native and Expo (or Flutter, when it fits), so a single, shared codebase compiles to a real, native app on both stores — with platform-perfect gestures, navigation, and polish on each.

iOS

Anatomy of an app people love

Every screen earns its place on the home screen

Downloads are easy; retention is the hard part. We design the whole journey — the first ten seconds, the daily loop, and the moment of payment — so the app is worth opening again tomorrow.

Onboarding that gets out of the way

No forced sign-up walls. We design a first run that shows value before it asks for anything — one-tap social login, sensible permissions requested only when they're needed, and a home screen that already feels personal.

02 · The daily loop

A home that rewards the second visit

The screen users see most gets the most care — fast, thumb-friendly, and personalised. Smart defaults, saved state, and instant search mean the app feels quicker every time it's opened.

Apps we build

One team, every kind of app

From a founder's first MVP to a multi-role platform — if it lives on a phone, we've built one like it. Here are the app types businesses ask us for most.

Parcels ready for dispatch — food, grocery, and on-demand delivery app development

Delivery & on-demand apps

Food, grocery, medicine, and courier apps with live order tracking, driver and rider apps, route maps, and real-time status — the full three-sided build: customer, partner, and admin.

Team scheduling on screens — booking and appointment app development

Booking & appointment apps

Salons, clinics, gyms, and services — slot booking, reminders, staff calendars, and in-app payments that cut no-shows and phone tag.

Boutique clothing rail — commerce and D2C brand mobile app development

Commerce & D2C brand apps

Native shopping apps for retailers and D2C brands — wishlists, push offers, one-tap reorder, and a checkout that outperforms the mobile web.

Analytics dashboard on a laptop — fintech and wallet mobile app development

Fintech & wallet apps

Wallets, lending, and finance apps built to the standard money demands — biometric auth, encryption, KYC flows, and audit-ready transaction logs.

People reviewing progress together — health and fitness app development

Health, fitness & lifestyle apps

Trackers, tele-health, and habit apps — wearable and HealthKit/Google Fit sync, streaks, and reminders that build a daily routine.

Warehouse shelving — staff, field, and internal operations app development

Staff, field & internal apps

Internal tools your team actually opens — field data capture, attendance, inventory, and dashboards that work offline and sync when there's signal.

Built in, not bolted on

The hard parts of a great app, handled by default

Push notifications

Segmented, scheduled, and deep-linked push via FCM and APNs — with in-app messaging and analytics on what actually re-engages.

Offline-first

Local caching and background sync so the app keeps working with no signal and reconciles cleanly when connectivity returns.

Payments

UPI, cards, netbanking, and wallets via Razorpay for India; Stripe, Apple Pay, and Google Pay for global — PCI-safe by design.

Maps & location

Live tracking, geofencing, and route optimisation with Google Maps and Mapbox for delivery, mobility, and field apps.

Auth & security

Social and OTP login, biometric unlock, encrypted storage, and role-based access — secured to store and data-protection standards.

Analytics & crash reporting

Funnels, retention, and events wired from day one with Firebase and Amplitude, plus Sentry crash reporting so nothing ships blind.

Over-the-air updates

Ship fixes and features without waiting on store review, using CodePush / EAS Update — users stay current automatically.

Backend & APIs

Node.js and serverless backends, real-time sync, and clean REST/GraphQL APIs — or we plug neatly into the systems you already run.

Already have an app?

App crashing, slow, or costing too much to maintain? We fix that.

A free, honest technical review of your current app — stability, speed, store compliance, and maintenance cost — with a clear plan to fix, modernise, or rebuild cross-platform. Whether or not you hire us.

How we work

From idea to the App Store, in five clear steps

No black boxes and no surprise invoices — a fixed quote, a working build every two weeks, and one senior team accountable from the first sketch to the first five-star review.

  1. Discover

    Week 1

    A free consultation about your users, your goals, and the one job the app must do brilliantly — followed by a fixed, itemised quote and a milestone plan.

  2. Design

    Weeks 1–3

    User flows, a clickable prototype, and a full UI kit shared as an interactive preview — you tap through the real app before a line of code is written.

  3. Build

    Weeks 3–10

    Two-week sprints with a working build in your hands every fortnight via TestFlight and Play Console — features on both platforms at once, tested on real devices.

  4. Ship

    Launch

    Store listing optimisation, screenshots, review submission, and phased rollout — we handle App Store and Play Store approval so you don't have to.

  5. Grow

    Ongoing

    Crash-free monitoring, OTA updates, A/B tests, and new features on a roadmap — we stay accountable for retention and ratings, not just the launch.

FAQ

Mobile app development, answered

The questions founders and business owners ask before trusting us with their app — answered straight, with no fine print.

How much does it cost to develop a mobile app?

It depends entirely on scope — a focused first version costs far less than a multi-role platform with delivery tracking and payments. We don't publish fixed prices because no two apps are the same; instead, after a free consultation you get a fixed, itemised quote with a milestone timeline, so you know the full cost before we start. No hourly billing, no surprises.

Do you build for both Android and iOS?

Yes — and usually from a single codebase. We build with React Native or Flutter so one project compiles to real, native apps on both the Play Store and the App Store, with platform-appropriate design on each. You get both platforms for close to the cost and timeline of one, and every future feature lands on both at once.

How long does it take to build an app?

A well-scoped first version typically launches in 6–12 weeks; larger, multi-role platforms take longer. You get a milestone timeline before we start and a working build in your hands every two weeks through TestFlight and the Play Console, so you're never waiting in the dark.

Should I choose native, React Native, or Flutter?

For most business and startup apps, React Native or Flutter is the smart choice — one codebase, both stores, and near-native performance. Fully native (Swift/Kotlin) makes sense for graphics-heavy games or apps leaning hard on the newest platform APIs. In your free consultation we recommend the approach that fits your product and budget, even when it means the leaner option.

Will you publish the app to the App Store and Play Store for me?

Yes. We handle the full submission for both stores — developer account setup, app icons and screenshots, store descriptions optimised for search (ASO), privacy declarations, review submission, and a phased rollout. If your app is rejected for any reason, we resolve it and resubmit at no extra charge.

Can you build a food delivery, taxi, or other on-demand app?

Yes — on-demand apps are a speciality. We build the full three-sided system: a customer app, a partner or driver app with live location, and an admin panel for dispatch, pricing, and payouts, all with real-time tracking, maps, and integrated payments. The architecture is designed to scale from your first city to many.

Do you design the app, or do I need a designer first?

We design it end to end. Our team maps the user flows, designs every screen, and shares a clickable prototype you can tap through before development begins — no separate design agency required. If you already have designs or a brand kit, we'll build to them faithfully.

What happens after the app launches?

Launch is the start, not the end. Every project includes a post-launch support window, crash-free monitoring, and over-the-air updates for fast fixes. Most clients continue on a maintenance plan covering OS updates, store compliance, security patches, and new features — plus analytics reviews to keep ratings and retention climbing.

Can you update or rebuild my existing app?

Yes. We take over apps built by other teams — fixing crashes and performance, modernising an outdated codebase, or rebuilding cross-platform to cut maintenance cost. We start with a free technical review of your current app and a clear, honest plan before recommending any rebuild.

Do you work with international clients and startups?

Yes. Alongside businesses across West Bengal and India, we build apps for founders in the US, UK, Europe, Australia, and the Middle East. Projects run remotely with fortnightly builds, guaranteed working-hours overlap, and communication over Zoom, Slack, or WhatsApp — you always know exactly where the build stands.
