NYC-grade mobile, shipped fast.
NYC mobile work splits across three domains. Fintech apps handle consumer budgeting, B2B treasury, and payment flows where NYDFS 23 NYCRR 500 hits on day one. B2B SaaS apps need dashboard parity with the web product. Delivery operators need real-time tracking and driver tooling. Compliance and onboarding typically consume 40% of the budget.
We build these apps in native iOS and Android, React Native, or Flutter. Work runs from our NoMad HQ with in-person discovery in Manhattan. For the broader NYC context, see our main New York agency page. This page covers stack choice, compliance, and timeline.
- NYC mobile concentrates on fintech (NYDFS 23 NYCRR 500 from week one), B2B SaaS dashboards, and delivery, plus DTC and media apps.
- React Native ships a both-platform MVP in 10-14 weeks; native (Swift/Kotlin) only when performance or hardware demands it.
- Fintech compliance is layered up front: PCI DSS, SOC 2 Type II, GLBA, plus NYDFS for regulated NYC entities.
- End-to-end App Store + Play Store submission handled, including iOS 18 ATT and SKAdNetwork setup.
- Ongoing maintenance is three recurring streams: OS-version compliance, dependency patching, crash/analytics monitoring.
Eastern Time. The same clock as our New York HQ.
New York runs on Eastern Time (ET). That's the same clock as our NoMad HQ where this work happens. You get a full working-day overlap plus in-person sessions when you need them. The clock below shows our shared working window.
React Native or native? Decided in discovery.
React Native wins for most NYC DTC, media, B2B SaaS, and delivery MVPs. One shared codebase. A 10-14 week both-platform launch. A hiring pool that overlaps React web.
Native Swift and Kotlin is reserved for performance-critical fintech and games. The decision gets made in discovery week one, not assumed upfront.
| 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 + delivery MVPs | Fintech perf-critical, games |
We handle App Store and Play Store submission end-to-end. iOS 18 ATT prompts, SKAdNetwork setup, provisioning, and App Store Connect metadata. Play signing keys, target SDK compliance, and pre-launch review. Shopify integration runs through the Storefront API for custom React Native commerce apps.

"Most NYC mobile briefs are fintech or B2B SaaS where compliance is the project, not a checkbox. NYDFS, PCI, SOC 2 get baked into the threat model in week one. And we're a subway ride away."
Five answers on NYC mobile development.
React Native or native iOS and Android for New York brands?
React Native wins when you need speed and economics. A typical MVP ships in 10 to 14 weeks across both platforms with one engineering team. Use native (Swift, Kotlin) when the app needs deep device-hardware integration, 60+ FPS rendering, complex gesture systems, or a hand-off to an existing native team. Most NYC DTC, B2B SaaS, and delivery brands ship React Native 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 submission includes app-review compliance. That's ATT prompts for iOS 18, data-collection disclosures, SKAdNetwork setup, provisioning profiles, and App Store Connect metadata. Google Play submission includes signing keys, Console setup, target SDK compliance, and pre-launch report review. Expect 3-7 days for Apple and 1-3 days for Google on first submission. Later releases move faster.
What does New York fintech mobile compliance require?
Compliance is layered. PCI DSS applies to any card-data handling. Stripe or Plaid hosted flows can reduce scope. SOC 2 Type II is needed for SaaS fintech serving enterprise. GLBA covers consumer financial products. For regulated NYC entities, NYDFS 23 NYCRR 500 requires access controls, encryption, incident response, and annual certification. We bake all of this into threat models and data-flow diagrams in the first two weeks, not later.
Can you integrate with our New York Shopify store?
Yes. Multiple paths exist. Shopify Mobile Buy SDK works for native apps. The Storefront API works for React Native. Builders like Tapcart and Vajro handle commerce-only use cases. For brands needing brand-critical design control plus commerce, a custom React Native app on the Storefront API is standard. Expect 10-14 weeks for a mid-market DTC app with product sync, cart, checkout, and push notifications.
What ongoing maintenance do New York mobile apps need?
Three recurring streams. OS updates: iOS drops a major version each September, Android each August. Both need target SDK updates within 6-12 months or store listings degrade. Security and dependency patching for React Native or native SDKs happens monthly. Analytics and crash monitoring via Sentry or Crashlytics with weekly rank and rating review. Retainer clients get all three with monthly billing and quarterly reports. One-off builds get a 90-day post-launch support window.
