Mobile app development is the process of planning, designing, building, testing and publishing software for smartphones and tablets, together with the backend services the app depends on. VOCSO handles the whole lifecycle for iOS and Android. We start with discovery to agree on users, core features, integrations and success metrics, then recommend native development (Swift for iOS, Kotlin for Android) or a shared Flutter or React Native codebase, with the trade-offs in writing. Our designers produce a clickable prototype before development begins. Engineers then build the app, its APIs and admin panel in sprints, with installable test builds along the way. Every release is tested on real devices and taken through App Store and Google Play review. After launch we monitor crashes, keep the app current with new OS versions and store policies, and ship new features. The work is done in-house by 25+ engineers, designers and QA specialists under ISO/IEC 27001 certified processes.
Mobile app UI/UX design. Design is available with development or as a standalone engagement: user research, user flows, wireframes and Figma prototypes that follow Apple's Human Interface Guidelines and Google's Material Design. We also redesign existing apps whose navigation or onboarding is costing them users. Browse our UI/UX design portfolio.

Transparency on every decision Talented Team of AI Engineers Smooth Collaboration & Reporting Efficient & Adaptive Workflow Strict Privacy Assurance with NDA 12 Months Free Post-Launch Support On-time Delivery, No Surprises ISO 27001 Certified EngineeringA mobile app development company turns an app idea into a published, maintained product. At VOCSO that means discovery and scoping, UI/UX design, iOS and Android development (native or cross-platform), the backend, APIs and admin panel, quality assurance on real devices, App Store and Google Play submission, and support after launch. You work with one in-house team and a project manager instead of coordinating separate designers, developers and testers. We have built software since 2009 and delivered 600+ projects, including mobile apps such as Avantha's employee communication app, the Photobecho stock-photo app and the ConsultEase expert consultation app.
Build cross-platform (Flutter or React Native) when you need iOS and Android on one budget and the app is mainly screens, forms, payments, chat and notifications; that covers most business apps. Build native (Swift and Kotlin) when the app depends on heavy graphics, AR, real-time media or the newest OS features, or when peak performance on low-end devices is essential. The table below summarises the trade-offs. Our hybrid app development page goes deeper into Flutter, React Native and Ionic, and we put our recommendation and its reasoning in every proposal.
| Factor | Native (Swift / Kotlin) | Cross-platform (Flutter / React Native) |
|---|---|---|
| Codebases | Two, one per platform | One shared codebase |
| Build and maintenance cost | Higher | Lower for most apps |
| Performance | Best, especially for graphics-heavy apps | Close to native for typical business apps |
| New OS features | Available immediately | Sometimes need a native module |
| Best for | Games, AR, media, deep device integration | MVPs, marketplaces, booking, internal and e-commerce apps |
Mobile app projects at VOCSO start at a $10,000 minimum engagement, and most complete apps fall between $30,000 and $150,000. The main cost drivers are the number of platforms and user roles, the depth of UI design, the backend and admin panel, integrations such as payments, maps or video calling, offline support and security or compliance requirements. A cross-platform build usually costs less than two separate native apps. We work on fixed scope, as a dedicated team billed monthly, or on time and materials. For an early ballpark, use our project cost estimator, then ask us for a scoped quote.
Yes. You can hire VOCSO as a mobile app design company for UI/UX alone, or combine design with development. A design engagement typically covers user research, user flows, wireframes, visual design and a clickable Figma prototype that follows Apple's Human Interface Guidelines and Google's Material Design. You receive design files and a component library that any development team can build from. We also audit and redesign existing apps when ratings or retention suffer from confusing navigation or onboarding. Examples of our interface work are in the UI/UX design portfolio.
Yes. Almost every app needs a backend for sign-in, data storage, push notifications, payments and an admin panel to manage users and content, and we build it with the app. Our usual stack includes Node.js, Strapi, PostgreSQL and Firebase, hosted on AWS or your own cloud. For ConsultEase we built the Android and iOS apps alongside the web platform, real-time calling with Agora and a wallet with per-minute billing. If you already have a web system or CRM, we connect the app to it through APIs, and our backend development services team handles larger server-side builds.
VOCSO is certified to ISO/IEC 27001 for information security and ISO 9001:2015 for quality management, and those controls apply to every mobile project. We sign an NDA before you share details, keep code in access-controlled repositories, use encrypted storage and HTTPS for app data, and follow platform guidance on authentication, permissions and secure storage on the device. Payment flows use PCI-compliant gateways such as Stripe, Razorpay or PayU rather than handling card data ourselves. You own the complete source code, designs and intellectual property, and we recommend publishing under your own Apple and Google developer accounts.
After launch we offer support and maintenance on a monthly plan or as needed. That covers bug fixes, updates for new iOS and Android versions and changing store policies, crash and performance monitoring, security patches and new features based on user feedback. Many apps launch as an MVP and grow through regular releases, so we plan a post-launch roadmap with you. If you need ongoing capacity, you can retain a dedicated development team that knows your codebase. A project manager stays your single point of contact, and every request is tracked through to release.
VOCSO combines India-based rates with an established, certified team: building software since 2009, 600+ projects delivered, 25+ in-house engineers, designers and QA specialists in Faridabad, and ISO/IEC 27001 and ISO 9001:2015 certification. We build native Android and iOS apps as well as cross-platform apps, so our platform advice is not tied to one technology. Our work includes StackRoom, our own asset-tracking product shipped on iOS, Android and the web. Engagements start at $10,000, with fixed-scope, dedicated-team and time-and-materials options.
