BulkBeings is a mobile app development company in Chennai, India, building native iOS and Android and cross-platform apps that follow your users to every edge — fast at 60fps, offline-capable, real-time, AI-powered on-device, biometric-secured, and shipped to the App Store and Play Store with the reliability of real engineering.
A mobile app is the hardest surface in software to get right. It runs on a device you don’t control, on a network that comes and goes, under a battery budget and an app-store reviewer — and users abandon it in seconds if it stutters or leaks their data. Most “app development” treats this as a template job. As a mobile app development company in Chennai, India, we treat it as engineering, and we do both sides of the platform: native iOS in Swift and SwiftUI, native Android in Kotlin and Jetpack Compose, and cross-platform in React Native, Flutter and Expo — one engineered codebase or two, chosen for your product.
We build native app development when the platform matters — deep hardware access, buttery 60fps rendering, biometric auth, wearables, IoT companion apps, AR/VR and super-app surfaces — and cross-platform app development when one codebase should serve both stores faster, with the choice driven by your product, not our comfort. Every build is offline-first with conflict-safe real-time sync, hardened with biometric authentication and secure on-device storage, wired for push notifications and deep linking, and instrumented so you can see how it behaves in the wild, not just the simulator.
And because intelligence is in our DNA, we put AI mobile app development where it belongs — on the device. On-device and edge ML inference with Core ML and TensorFlow Lite power private, low-latency features, on-device LLMs that run without a round-trip, and app experiences that get smarter without shipping your users’ data to someone else’s API. From custom mobile app development for startups to enterprise mobile app development at scale, we own the mobile backend, the BaaS layer, the real-time APIs and the CI/CD pipeline that keeps releases boring.
It all ships certified and compliant with SOC 2, ISO 27001 and GDPR — with HIPAA or PCI-DSS layered in where the app touches health records or payments, so fintech app development and healthcare app development pass their audits, not just their demos. We handle app store optimization (ASO), staged rollouts and App Store and Play Store submission end to end, and instrument every release with crash analytics and performance telemetry. That is the difference between an app that uses AI and one that’s engineered with it — the difference teams get when they hire mobile app developers in India who ship like a product team, not a template shop.
From the first native screen to the last app-store submission, every layer is engineered in-house so your app isn’t a template you rent by the month.
Swift and SwiftUI on iOS, Kotlin and Jetpack Compose on Android — native app development that uses the platform to the fullest, holding a smooth 60fps where every millisecond, gesture and haptic matters.
One engineered codebase serving iOS and Android with near-native performance — React Native, Flutter, Expo and Kotlin Multiplatform, the right call when speed to both stores beats platform-specific depth, without shipping a webview in disguise.
Local-first data, conflict-safe real-time sync and graceful degradation so the app keeps working in a tunnel, a warehouse or a flight — and reconciles cleanly the instant the signal returns.
On-device and edge ML inference with Core ML, TensorFlow Lite and on-device LLMs, plus cloud AI when it’s warranted — private, low-latency intelligence that runs in the binary, not a black-box API.
Biometric auth, secure storage, push notifications and the real-time GraphQL and WebSocket APIs behind the app — a mobile backend and BaaS layer certified and compliant with SOC 2, ISO 27001 and GDPR, with HIPAA or PCI-DSS where the app demands it.
CI/CD for mobile with Fastlane, staged rollouts, deep linking, app store optimization (ASO), crash and performance monitoring, and App Store and Play Store submissions that pass review the first time.
watchOS and Wear OS wearable apps, IoT companion apps for connected hardware, and AR/VR surfaces — the connected-device experiences that extend your product beyond the phone.
Rescue and re-platform legacy apps — hybrid-to-native rebuilds, Objective-C to Swift, Java to Kotlin, and PWA or super-app strategies — modernized for performance, security and the current OS matrix.
A disciplined path from your concept to an app running on real devices in real hands — every stage measured, nothing hand-waved.
We start from the user and the outcome, not the framework — what job the app does, on which devices, under what compliance constraints. That defines native versus cross-platform before a line is written.
We build the critical flows early on real hardware, because an app lives or dies on how it feels in the hand — cold-start, scroll and gesture — not how it looks in a mockup.
Architecture, offline data model, real-time sync, state and the native or cross-platform foundation — built once, properly, so the app scales in features without collapsing under them.
On-device AI, mobile backends, sync, push notifications, deep linking and payments come together behind the interface — grounded in your systems, secured with biometrics, and instrumented from the start.
Performance passes to 60fps, device-matrix testing, security hardening against your compliance bar, crash-proofing, ASO and store submission — the app lands in the App Store and Play Store, not a build folder.
Crash analytics, performance telemetry and staged releases keep quality holding as OS versions, devices and user load change over time.
We’re platform-agnostic — we pick native or cross-platform for what the product needs and own the whole pipeline around it, security and compliance included.
Why teams that could buy an app-template shop choose to engineer the app with us instead.
Whether it’s Swift, SwiftUI, Kotlin, Jetpack Compose, React Native or Flutter, the app feels native — fast cold starts, a steady 60fps and gestures users never think about.
Offline-first architecture with real-time sync means the app keeps doing its job in a dead zone and reconciles cleanly when the signal returns — not a spinner and an error.
On-device intelligence, biometric auth and secure storage give you private, low-latency features certified and compliant with SOC 2, ISO 27001 and GDPR — the applied-AI and security depth we bring to every build.
We build mobile apps where they measurably move the numbers — in regulated, operationally demanding sectors, not toy demos.
HIPAA-ready clinical and patient apps that work offline at the bedside, protect data on-device with biometrics and cut administrative load for care teams.
Mission-critical apps for crews and ground ops that stay usable off-network, sync in real time and turn field data into real-time foresight.
PCI-DSS-ready B2B and B2C financial apps with hardened biometric auth, on-device protection and audit-ready flows users trust with money.
Industrial and IoT companion apps for the floor and the field — offline-first capture and machine-vision checks that work where Wi-Fi doesn’t reach.
The questions teams ask before they build a mobile app with us.
We build the app itself — native iOS in Swift and SwiftUI, native Android in Kotlin and Jetpack Compose, or cross-platform in React Native and Flutter — along with the secure mobile backends, real-time sync and on-device AI behind it, shipped to the App Store and Play Store. That’s different from a template shop: we engineer the whole stack to your product, not a boilerplate.
Cost depends on scope — platforms, feature depth, offline and real-time needs, AI, and compliance bar. A focused native or cross-platform MVP is a very different number from an enterprise app with HIPAA or PCI-DSS. We scope custom mobile app development to your outcome and give you a clear, staged estimate before engineering starts, so there are no surprises mid-build.
Yes — both stores, every engagement. We ship native iOS in Swift and SwiftUI and native Android in Kotlin and Jetpack Compose, or one cross-platform codebase in React Native or Flutter that serves both, and handle App Store and Play Store submission end to end.
It depends on the product, and we help you choose. Native app development gives the deepest platform integration, 60fps performance and hardware access for wearables, IoT and AR/VR; cross-platform app development with React Native or Flutter lets one codebase reach both stores faster and cheaper. We frame that decision around your users, timeline and feature depth before we write a line.
Both are excellent — we’re a React Native development company and a Flutter development company, so we’re not selling you a single hammer. React Native suits teams with JavaScript and TypeScript depth and heavy native-module needs; Flutter gives pixel-perfect UI and consistent performance from one Dart codebase. We recommend the one that fits your team, timeline and UI ambition.
Yes — offline-first is a default, not an add-on. We build local-first data models with conflict-safe real-time sync so the app keeps working in a tunnel, a warehouse or a flight, then reconciles cleanly the instant the connection returns.
Yes. AI mobile app development is in our DNA — we embed on-device and edge ML inference with Core ML, TensorFlow Lite and on-device LLMs for private, low-latency features that run without a round-trip, and add cloud AI only when the problem warrants it.
A prototype of the critical flows can be in your hands in weeks; a production app on the stores typically takes a few months, depending on platforms, scope and compliance. We prototype the feel early on real hardware, engineer the core once, then harden and ship — so timelines are staged and visible, never a black box.
Yes — we own delivery end to end: CI/CD with Fastlane, staged rollouts, app store optimization (ASO), and App Store and Play Store submissions engineered to pass review the first time, with crash analytics and performance telemetry wired in from day one.
Security is engineered in, not bolted on: biometric authentication, secure on-device storage, encrypted sync and hardened backends, certified and compliant with SOC 2, ISO 27001 and GDPR — with HIPAA or PCI-DSS layered in where the app handles health records or payments, so healthcare and fintech apps pass their audits.
Yes — from startup MVPs to enterprise mobile app development. Startups get a lean, well-architected app that can raise on and scale without a rewrite; enterprises get the security, compliance and reliability their bar demands. Either way you hire mobile app developers in India who ship like a product team.
We’re headquartered in Chennai, India, and work with teams worldwide. Engagements run remotely with clear cadence, and our work is enterprise-grade from the first commit.
