Mobile App Development
Native and Cross-Platform Mobile Applications Built for Performance, Retention and Scale
A mobile application is not just a smaller version of your website. It is a context-sensitive, always-on interface that has to work flawlessly in inconsistent network conditions, across a fragmented device landscape, within the constraints of two distinct operating systems and under the constant scrutiny of App Store and Google Play review processes. Building it correctly requires engineers who have shipped mobile applications in production — not developers who learned React Native from a YouTube course.
Vrintra Labs builds native iOS and Android applications for products where performance, hardware integration and platform-native UX are non-negotiable. We build cross-platform applications using React Native and Flutter for products where time-to-market and shared codebase efficiency justify the trade-offs. The framework decision is made based on your specific product requirements — not on what is easiest for us to staff.
Every application we ship includes UX design, full test coverage on real device labs, App Store and Google Play submission management and a post-launch monitoring setup that surfaces crashes, ANRs and performance regressions before your users report them in the reviews. Engagement models are flexible — fixed-scope for MVP builds, monthly retainer for ongoing feature development and dedicated engineer allocation for product teams that need embedded senior mobile engineering capacity.
What You Get
- Native iOS development (Swift, SwiftUI, Objective-C) and native Android development (Kotlin, Jetpack Compose)
- Cross-platform development using React Native and Flutter — one codebase, two platforms, native performance
- UX and UI design — wireframes, interactive prototypes, design system and production-ready screens for both platforms
- Backend and API development — RESTful APIs, GraphQL, real-time WebSocket connections and mobile-optimised data models
- Third-party integrations — payment gateways (Stripe, Braintree), mapping (Google Maps, Mapbox), analytics, push notifications and biometric authentication
- Offline functionality, background sync and local data persistence — apps that work when connectivity does not
- App Store and Google Play submission management — app review compliance, metadata, screenshots and release management
- Post-launch monitoring — crash reporting (Sentry, Firebase Crashlytics), performance metrics and iterative release management
Who This Is For
Startups building their first mobile product and needing a senior engineering team to own the entire build from UX to App Store submission. Enterprises adding a mobile channel to an existing platform. Product teams with an existing mobile app that needs performance engineering, a rewrite or additional feature velocity from senior engineers. Businesses with a web application that needs a native mobile companion.
Frequently Asked Questions
Everything you need to know about our mobile app development service.
We make this recommendation based on your specific product requirements. Native is the right choice when your app needs deep hardware integration (ARKit, complex camera processing, NFC), demands the absolute highest performance, or when your product strategy has different feature sets on each platform. Cross-platform is the right choice when your MVP needs to reach both platforms quickly, when your feature set is interface-driven rather than hardware-intensive, and when maintaining a single codebase matters for your team structure and budget. We will give you a clear technical recommendation with the trade-off analysis in writing.
Discovery and architecture (week 1–2): requirements, user flows, technical architecture and API contracts. Design (week 2–4): wireframes, UX flows and production-ready screens. Development (week 4–12+ depending on scope): two-week sprints with working builds delivered to TestFlight and Firebase App Distribution every sprint. QA and device testing (overlapping): automated tests plus manual testing on physical device lab covering the 20 most common device configurations. App Store and Google Play submission and review management. Post-launch monitoring setup.
Yes. We audit your existing API for mobile compatibility — response times, payload sizes, offline handling and authentication flows — before we begin. Where the existing API needs changes to support mobile patterns, we document those requirements and can implement them or work alongside your backend team. We design mobile clients defensively, never assuming the API is perfectly reliable.
We have managed hundreds of App Store submissions and we build rejection prevention into every engagement — reviewing every guideline that applies to your app before submission, resolving any compliance issues during development rather than after rejection, and preparing your review notes proactively. On the rare occasion a rejection occurs, we typically resolve and resubmit within 48 hours.
Three options: fixed-scope MVP build (defined features, agreed timeline and price — we commit to the scope, you commit to the decisions), monthly retainer for ongoing product development, or dedicated senior mobile engineer embedded into your team. Most early-stage products start with a fixed-scope MVP and move to a monthly retainer once they have market validation and a clear product roadmap.
