InfyTech is a USA-based mobile app development company building native iOS, Android, Flutter, and React Native apps. From business apps to CRM mobile apps to enterprise field service apps — we engineer apps that feel native, retain users, and ship on time.
99% of mobile apps are abandoned within 30 days of install. The 1% that survive share three traits: lightning-fast UX, obsessive attention to detail, and engineering that disappears into the experience. As a senior mobile app development company serving USA clients, InfyTech builds the 1%.
We've shipped apps across native iOS (Swift, SwiftUI), native Android (Kotlin, Jetpack Compose), React Native (TypeScript + Expo), and Flutter (Dart). Each technology has its sweet spot — we don't push you into the framework we're most comfortable with. We pick the right tool for your specific project, audience, and roadmap.
Our portfolio spans every major category of business app development:
Swift, SwiftUI, Apple frameworks. Haptics, Dynamic Island, Live Activities. Apps that feel inevitable on iPhone and iPad.
Kotlin + Jetpack Compose. Material Design 3. Apps right at home on every device — foldables, Wear OS, Auto.
Dart + Flutter 3. Pixel-perfect on iOS and Android. Custom animations that feel handcrafted.
One codebase, two platforms, native performance. TypeScript + Expo. Perfect for fast-moving teams.
With React Native and Flutter, we deliver apps that feel native on both iOS and Android — at roughly 60% of the cost of building two separate native apps. For most business use cases, this is the right tradeoff. For consumer apps demanding the absolute best performance, we go native. We help you make the right call.
Field service apps, monitoring apps, sales apps — anything used outside of perfect WiFi — needs offline-first architecture. We design data layers with intelligent caching, conflict resolution, and graceful sync so your app works whether the network does or not.
HIPAA, PCI-DSS, SOC 2, biometric authentication, certificate pinning, encrypted storage — we build these in from the start, not bolted on at the end. Your data stays safe and your business stays compliant.
We've shipped to the App Store and Play Store hundreds of times. We know what Apple's reviewers reject (and why). We pre-empt issues with permissions handling, privacy disclosures, content guidelines, and crash-free quality bars — so your first submission gets approved.
Native mobile companion apps for your CRM — leads, attendance, dashboards on the go.
Real-time tracking, dispatch, incident reporting, and on-site workflows for distributed teams.
Field service, inventory, internal tools, and workflow apps for company-wide deployment.
Shopping experiences with cart, checkout, payments, push notifications, personalization.
Secure financial apps with biometric auth, transactions, KYC, and compliance built in.
HIPAA-compliant apps for patients, providers, telemedicine, and wellness tracking.

Sentry, Crashlytics, real-time alerts for prod issues.
Submission, review responses, and ASO.
Market research, competitor analysis, prioritization.
User flows, wireframes, design system, user testing.
Bi-weekly sprints, TestFlight/Play internal builds.
Device testing, performance, real-user beta program.
Store submission, ASO setup, post-launch support.
Mobile apps mean different things in different industries. We've shipped across most of them:
Mobile monitoring apps for security firms — geofenced check-ins, incident submission, real-time alerts.
Agent productivity apps, supervisor dashboards, and customer-facing service apps.
Driver apps, dispatch tools, route optimization, proof-of-delivery with photo and signature capture.
HIPAA-compliant patient apps, provider tools, telemedicine clients, and medication reminders.
Native shopping apps, loyalty programs, and store-locator tools with push-driven promotions.
Job-site apps with offline capability, photo documentation, time tracking, and client signatures.
Most agencies are either "native shops" or "React Native shops." We're senior in both — and we'll tell you honestly which approach fits your project. Sometimes that means saying "build it in React Native to save 40% of your budget." Sometimes it means "go native iOS-first for that target audience." We're not financially incentivized to push one over the other.
Mobile development is unforgiving. App Store rejections, Android fragmentation, OS version compatibility, performance optimization on low-end devices — these require senior judgment, not pattern-matched solutions. Every InfyTech project is led by engineers with 5+ years of mobile experience.
Crash reporting, analytics, push notifications, authentication, deep linking, in-app purchases, app store ASO — these aren't add-ons in our projects, they're defaults. Your app launches with everything a serious business app needs.
iOS updates every September. Android updates every August. New APIs, deprecated APIs, broken third-party libraries, changing review policies — mobile apps require ongoing attention. We offer monthly maintenance retainers so your app stays current, secure, and fast year after year.
Mobile app pricing reflects complexity, platform coverage, backend requirements, and integrations. After a free discovery call, we provide a fixed-price proposal with clear scope and milestones. MVPs and focused single-platform builds are significantly less than multi-platform enterprise apps with complex backends, offline-first architecture, and compliance requirements.
Depends on your audience. In the USA, iOS users spend more on average but Android has higher install volume. For consumer apps targeting US-based audiences, we usually recommend both — and we build them simultaneously with React Native or Flutter to keep costs efficient. For business and internal apps, we often start with one platform and add the other based on demand.
Both are excellent. React Native is better when you're already invested in the React ecosystem, hiring developers, or need maximum third-party library availability. Flutter is better for highly custom UIs, complex animations, and when you want absolute pixel consistency between iOS and Android. We use whichever fits your specific project — and we're senior in both.
Yes if needed. We build offline-first apps using SQLite, WatermelonDB, Realm, or other local data stores with intelligent sync when connectivity returns. This is critical for field service apps, monitoring apps, sales apps used in poor-signal environments, and any app where reliability matters.
Yes — submission, review responses, and App Store Optimization (ASO) are included in every app project. We handle Apple Developer Program enrollment guidance, asset preparation (icons, screenshots, descriptions), review process, and any rejection appeals. Most apps go live within 1–2 weeks of submission.
Every app ships with: encrypted local storage, certificate pinning, biometric authentication options, secure API communication (TLS 1.3), token-based auth with refresh rotation, jailbreak/root detection where required, and protection against common OWASP Mobile Top 10 vulnerabilities. For HIPAA, PCI, or other compliance, we add the additional controls required.
Yes — CRM mobile apps and business apps are a major part of our portfolio. We've built native mobile companions for sales teams (leads, pipeline, contacts on the go), field service apps (work orders, signatures, photo capture), attendance apps (geofenced check-in/out), and internal operations apps. We've also built the mobile monitoring app for the Netex Solution surveillance platform.
Yes. Every app project includes 90 days of free post-launch support. After that, monthly maintenance retainers start with custom scoping covering OS update compatibility (iOS/Android annual updates), bug fixes, performance monitoring, security patches, analytics review, and minor feature additions.
Free consultation. We'll scope your MVP and outline a launch path.
