We design and develop native iOS & Android apps, cross-platform solutions with React Native and Flutter, and lightning-fast Progressive Web Apps — all built with a UI/UX-first philosophy for measurable engagement and retention.
A successful mobile or web application is far more than a polished interface. It is a living product that solves a specific user problem, integrates seamlessly with your backend systems, and continuously earns its place on the user's home screen. At Vianmax, we treat every engagement as a product partnership — not just a development contract. We invest time in understanding your users' real journeys before a single line of code is written.
Many businesses struggle with apps that look great in demos but fail in the wild — slow load times, confusing flows, poor offline behaviour, and zero analytics instrumentation. We solve these problems systematically. Our UI/UX team runs competitor analysis, wireframing, and usability testing before development begins, ensuring that the product we ship matches real user expectations.
Whether you need a native iOS app for a premium brand experience, a cross-platform Flutter solution to halve your development cost, or a PWA that works on any browser with offline-first functionality — our Chennai-based team delivers end-to-end, from concept to App Store submission and beyond, with post-launch monitoring and iterative improvement cycles built into every engagement.
Six pillars that separate a Vianmax-built app from a generic agency deliverable.
Purpose-built in Swift (iOS) and Kotlin (Android) to fully exploit each platform's capabilities — Face ID, push notifications, ARKit, background processing — delivering performance no hybrid wrapper can match.
Platform-perfect UX & performanceOne codebase, two stores. We use Flutter for pixel-perfect UI parity and React Native when JavaScript ecosystem integration is a priority — cutting cost without sacrificing the native feel users expect.
~40% lower build cost vs two native appsInstallable, offline-capable, and push-notification-enabled web apps that load in under 2 seconds on any device. Ideal for reach-first strategies where App Store friction is a barrier to acquisition.
No app store approval delaysUser personas, information architecture, wireframes, interactive Figma prototypes, and user-testing sessions conducted before development. We validate ideas early so you don't rebuild late.
Fewer revision cycles post-launchSeamless connection to REST and GraphQL APIs, payment gateways (Razorpay, Stripe), broker APIs, CRM systems, and third-party data providers — all handled with secure token management and robust error handling.
Fully connected, production-ready appsEvery app ships with Firebase Analytics, Mixpanel event tracking, and Crashlytics/Sentry error monitoring pre-configured so you have full visibility from day one — no retrofitting required after launch.
Data-driven iteration from launch dayA disciplined process that removes ambiguity and keeps every stakeholder aligned from the first sketch to the first App Store review.
We interview target users, audit competitor apps, map user journeys, and define success metrics. Deliverables: persona documents, flow maps, and a signed functional specification.
High-fidelity Figma prototypes — every screen, every state — validated by real users before engineering begins. Eliminates costly post-development redesigns.
Two-week sprints with daily standups, a shared Jira board, and weekly demo builds distributed via TestFlight / Firebase App Distribution so stakeholders test on real devices continuously.
Device matrix testing across 20+ device/OS combinations, penetration testing for auth and API layers, load testing for backend APIs, and Lighthouse/Core Web Vitals audits for PWAs.
We handle App Store and Google Play submissions, ASO (App Store Optimisation) metadata, phased rollouts, and post-launch monitoring with monthly analytics reviews for 90 days.
Carefully chosen technologies that are battle-tested, well-supported, and right for each layer of the stack.
Real-time market data apps, portfolio trackers, broker-integrated trading dashboards, and personal finance management tools with bank-level security and sub-second data refresh.
Student-facing LMS apps, assessment tools, video lecture streaming, live quiz modules, and progress dashboards — designed for engagement and optimised for low-bandwidth Indian networks.
Mobile-first storefronts, real-time inventory management, barcode scanning, loyalty programme apps, and seamless Razorpay/UPI checkout flows with one-tap repeat orders.
Patient appointment apps, lab result portals, medication reminder tools, and teleconsultation platforms built with HIPAA-aligned data handling and accessibility standards.
Internal tools for field sales teams, asset tracking apps, maintenance workflow apps, and HR self-service portals that work reliably on low-end Android devices with offline-first architecture.
Traders needed live P&L dashboards, strategy performance analytics, and one-tap order management on mobile — with sub-200ms data latency during market hours.
Flutter app with WebSocket-driven live data, background fetch for alerts, Zerodha/Upstox broker API integration, biometric auth, and a fully offline-capable portfolio view.
📈 Achieved <180ms data refresh in live market conditions. 4.7★ rating across both stores.
Students across 30+ colleges needed offline video access, live quiz participation, and certificate downloads — on a wide range of Android devices from budget to flagship.
React Native app with offline video caching (Expo AV), adaptive bitrate streaming, push notification reminders for deadlines, and DRM-protected content for premium courses.
🎓 93% course completion rate for offline-capable courses vs 61% for web-only students.
We don't just write code. We think in retention rates, conversion funnels, and App Store rankings — then build accordingly.
Every project begins with a validated prototype before any development starts — eliminating the most expensive type of rework.
iOS, Android, PWA, and web — delivered by the same team with a shared design system, consistent UX, and unified backend.
Having built AlphaSync™ — a live trading platform used by thousands of traders — we understand the performance, security, and latency demands of financial apps.
Vianmax Academy's mobile infrastructure serves students across more than 30 institutions, proven to handle concurrent usage spikes during live sessions.
We handle all App Store Connect and Google Play Console submissions, including ASO, review response strategy, and phased rollout planning.
Retainer-based growth support with monthly analytics reviews, feature prioritisation workshops, and rapid iteration sprints included post-launch.
It depends on your priorities. Native (Swift/Kotlin) is best for apps that need deep platform integration — hardware features like ARKit, ultra-low latency, or a flagship brand experience. Flutter or React Native are excellent for most business apps, reducing cost by 30–40% while delivering a near-native feel. During our discovery phase, we assess your feature list, budget, and target audience to recommend the right approach — not the most expensive one.
A straightforward app with 8–12 screens typically takes 10–14 weeks from kickoff to App Store approval. Medium-complexity apps (20–30 screens, custom backend, payment integration) run 16–22 weeks. Enterprise-grade apps with complex data models and custom hardware integrations can take 6–9 months. We give firm timelines after the discovery phase once the full feature scope is signed off — not before.
Yes, fully. We prepare all submission metadata — screenshots, preview videos, App Store description with keyword-optimised copy, privacy policy documentation, age ratings, and data disclosure forms. We manage the review process, respond to reviewer queries, and handle resubmissions if needed. We've maintained a near-100% first-submission approval rate by following platform guidelines strictly during development rather than retrofitting at submission time.
Absolutely. App modernisation is a significant part of our workload. We audit your existing codebase for technical debt, outdated dependencies, and architectural problems, then present a phased modernisation plan. Depending on the state of the existing app, this may involve a UI refresh on the existing codebase, a complete rewrite in Flutter, or a gradual module-by-module migration strategy that avoids disrupting your existing user base.
This is a critical consideration for the Indian market. We test every build on a physical device matrix that includes entry-level Android devices (2GB RAM, MediaTek processors) as well as flagships. We use image compression pipelines, lazy loading, background data prefetch, and adaptive quality settings to ensure smooth performance across the full device spectrum. Our EdTech apps, for example, are optimised to run on Android Go devices used by students in Tier 2 and Tier 3 cities.
All projects include a 90-day post-launch warranty covering bug fixes and critical patches at no charge. Beyond that, we offer monthly retainer plans covering OS version compatibility updates, analytics review meetings, feature prioritisation workshops, and sprint-based feature development. We typically recommend retainers for apps in active growth phases where rapid iteration based on user data drives significant improvements in retention and conversion.
Most apps are deleted within 30 days. Ours aren't — because we start with the user, not the feature list. Let's design something people genuinely want.
