Mobile App Development for iOS, Android, and Cross-Platform

Native performance where it matters, cross-platform speed where it counts

We build native iOS and Android apps, cross-platform apps with Flutter and React Native, and progressive web apps — choosing the approach based on your budget, timeline, and performance requirements, not a one-size-fits-all default. Every app we ship is built with the App Store and Play Store review guidelines in mind from day one, so launch isn't held up by avoidable rejections.

Native & Cross-Platform

Swift/Kotlin for native performance, Flutter and React Native for shared-codebase speed and budget efficiency.

Store-Ready Compliance

Built against App Store and Play Store guidelines from the start, reducing review rejections and delays.

Security & Compliance Built In

PCI-DSS, HIPAA, and GDPR-aware development for apps handling payments or sensitive user data.

Choosing the Right Approach for Your App

The native vs. cross-platform decision shapes your budget, timeline, and how the app feels in a user's hand. We help you choose based on your actual requirements — camera-heavy AR features usually need native, most business apps do fine cross-platform.

Talk to Our Team

Native iOS Development

Swift and SwiftUI builds for apps needing deep hardware integration or the smoothest possible iOS-native feel.

Native Android Development

Kotlin builds optimized for the fragmented Android device landscape and Play Store performance requirements.

Cross-Platform with Flutter/React Native

One codebase shipping to both platforms — faster to market and easier to maintain for most business apps.

Progressive Web Apps

App-like experiences delivered through the browser, no app store approval required, ideal for lightweight tools.

Post-Launch Support

OS update compatibility, bug fixes, and feature iteration after your app is live in the stores.

A Mobile Stack Matched to Performance and Timeline Needs

Native, cross-platform, or PWA — we work across the full spectrum and help you avoid over-building for a v1 that doesn't need it yet.

Native Development

Swift/SwiftUI for iOS, Kotlin for Android — for apps needing maximum performance or deep OS integration.

Cross-Platform

Flutter and React Native for one codebase across both platforms, cutting build and maintenance cost.

Backend & Cloud

Firebase, AWS, and custom Node.js APIs powering authentication, push notifications, and data sync.

Why Platform Fit Beats Platform Hype

Most business apps don't need native performance on day one — they need to ship, get user feedback, and iterate. We help you pick the approach that gets real users testing your app faster.

Our Mobile App Development Process

Mobile projects live or die on early decisions — platform choice, offline behavior, and how you'll handle app store review. We front-load those decisions so build phase doesn't hit surprises.

Five stages from concept to a store listing that passes review the first time.

Strategy & Platform Selection

We assess your feature list, budget, and timeline to recommend native, Flutter, React Native, or PWA.

Feature & platform scoping
Competitor app audit
Technical feasibility review
Budget & timeline planning

UX/UI & Prototyping

Wireframes and interactive prototypes following iOS Human Interface and Material Design guidelines.

User flow mapping
Interactive prototypes
Platform-specific UI patterns
Usability testing

Development & API Integration

Core app build alongside backend API development, third-party SDK integration, and offline-mode handling.

Native/cross-platform build
API & backend integration
Push notification setup
Offline data sync

QA Across Devices

Testing across real device matrices, not just simulators, covering performance, security, and edge cases.

Device & OS matrix testing
Performance profiling
Security testing
Beta testing (TestFlight/Play Console)

Store Submission & Support

App Store and Play Store submission handled against current review guidelines, followed by post-launch monitoring.

Store listing optimization
Review guideline compliance
Crash monitoring setup
Post-launch iteration

Mobile Expertise Across Industries and Compliance Needs

From consumer social apps to HIPAA-regulated healthcare tools, we bring platform-specific and industry-specific experience to every build.

Regulated Industries

HIPAA, PCI-DSS, and GDPR-aware architecture for healthcare, fintech, and e-commerce apps.

Offline-First Apps

Local data caching and background sync for apps that need to work reliably without connectivity.

DevOps & CI/CD for Mobile

Automated build pipelines and staged rollouts for faster, safer release cycles.

Why Businesses Choose Nexovah for Mobile App Development

We build apps meant to be maintained for years, not demoed once — with clean architecture, documented APIs, and a codebase your next developer can actually work with.

Right-Sized Tech Choices

We recommend native only when your feature set actually needs it, saving budget on most projects.

Store Compliance Expertise

Built against current App Store and Play Store guidelines to minimize review delays.

Security-Aware Development

PCI-DSS, HIPAA, and GDPR considerations built into architecture from day one where relevant.

Real-Device QA

Testing across actual device and OS matrices, not just simulators, before every release.

Post-Launch Iteration

OS update compatibility and feature development continue long after the initial store listing.

The tools behind the work

The tools are not the advantage. The advantage is knowing which tool owns which job — and wiring them together so the output is faster, cleaner, and more consistent than any single tool could deliver alone.

Mobile App Development — Frequently Asked Questions

Cross-platform (Flutter or React Native) is the right default for most business apps — faster to build, one codebase to maintain, and performance that's indistinguishable from native for typical use cases. We recommend native only when you need deep hardware access, AR/VR features, or absolute maximum performance.

A focused MVP typically runs $5,000 to $25,000+ depending on feature complexity, platform count, and backend requirements. We scope exact pricing after a feature and platform review.

An MVP typically takes 2 to 4 months. A full-featured app with custom backend, integrations, and polish typically takes 5 to 9 months.

Yes — we handle store listing preparation, guideline compliance review, and submission, and we build with review requirements in mind from the start to reduce rejection risk.

Yes, we have experience architecting healthcare and payment-handling apps with the security controls and data handling practices these regulations require.
