Mobile app development, New York.
Native iOS and Android, React Native, and Flutter builds for NYC DTC, fintech, media, and B2B brands. Eastern Time coverage, in-person discovery in Manhattan.
NYC-grade mobile. Shipped fast.
NYC mobile work splits into three categories we ship every year. DTC commerce apps for fashion and beauty brands that have outgrown a mobile-web experience and need push notifications, saved carts, and a home-screen presence. Fintech apps spanning consumer budgeting, B2B treasury, and compliance-heavy payment flows where NYDFS 23 NYCRR 500 compliance lands in discovery week one. Media and subscription apps for NYC publishers that need offline content, frictionless paywalls, and clean App Store review compliance for recurring subscriptions.
React Native or native? Decision in discovery.
| criterion | React Native | Native (Swift + Kotlin) |
|---|---|---|
| Time-to-market (MVP) | 10-14 weeks | 16-24 weeks |
| Codebase | Single, shared | Two, parallel |
| Performance ceiling | Plenty for commerce + content | Games + complex gestures |
| NYC hiring pool | Deep (overlaps React web) | Deep (Swift/Kotlin specialists) |
| Best for | DTC, media, B2B MVPs | Fintech perf-critical, games |
Looking for mobile app developers near you in NYC?
Our NYC mobile engineering team serves brands across Manhattan, Brooklyn, and the tri-state area. On-site discovery workshops and quarterly design reviews happen at your New York City office or ours. Past NYC mobile engagements covered DTC commerce for fashion brands in SoHo, fintech apps subject to NYDFS oversight, and subscription media apps with complex App Store subscription flows.
Five answers.
React Native or native iOS and Android for NYC brands?
React Native for brands prioritizing time-to-market and shared codebase economics — typical MVP in 10 to 14 weeks across both platforms with a single engineering team. Native (Swift for iOS, Kotlin for Android) when the app hits specific constraints React Native cannot cross: deep device-hardware integration, 60-plus FPS rendering requirements, complex gesture systems, or when the brand already has a native engineering team to hand off to. Most NYC DTC and media brands we work with ship React Native MVPs first and add native modules later for specific features.
Do you handle App Store and Play Store submission for NYC clients?
Yes, end-to-end. Apple App Store submission includes app-review compliance audit (ATT prompts for iOS 18, data-collection disclosures, SKAdNetwork setup), provisioning profiles, and App Store Connect metadata. Google Play submission includes signing keys, Play Store Console setup, target-SDK compliance, and pre-launch report review. Expect 3 to 7 days for Apple review and 1 to 3 days for Google on first submission; subsequent releases are typically faster.
What does NYC fintech mobile compliance require?
Layered scope. PCI DSS for any card data handling; scope reduction via Stripe or Plaid hosted flows is the standard approach. SOC 2 Type II for SaaS fintech clients serving enterprise. GLBA for consumer financial products. For NYC-specific requirements, NYDFS 23 NYCRR 500 applies to regulated financial entities — covers access controls, encryption, incident response, and annual certification. Our NYC fintech engagements bake these into the threat model and data-flow diagrams in the first two weeks rather than retrofitting later.
Can you integrate with our NYC Shopify store?
Yes. Shopify mobile integration paths include Shopify's Mobile Buy SDK for native iOS and Android, Shopify Storefront API for React Native implementations, and Shopify Mobile App builders like Tapcart and Vajro for faster commerce-only apps. For brands that need brand-critical design control plus commerce, a custom React Native app hitting the Storefront API is the standard pattern. Expect 10 to 14 weeks for a mid-market DTC mobile app with Shopify product sync, cart, checkout, and push-notification setup.
What ongoing maintenance do NYC mobile apps need?
Three recurring types. One, OS-update compliance — iOS ships a major version each September and Android each August; both require target-SDK updates within 6 to 12 months or store listings degrade. Two, security and dependency patching for React Native or native SDKs, typically monthly. Three, analytics and crash monitoring via Sentry or Crashlytics plus weekly rank and rating review. Retainer clients get all three on a monthly cadence with quarterly written reports; one-off builds get a 90-day post-launch support window.
