WHAT
WE
OFFER
Mobile App Development Experts ServingNew York Businesses
From native builds to AI-powered features, we pick the stack that fits your product — not the one that's easiest for us.
iOS App Development in New York
We build in Swift and SwiftUI to Apple's Human Interface Guidelines and submit directly to App Store Connect ourselves, with NYC-based project leads for your check-ins.
Android App Development in New York
We develop native Android apps in Kotlin, built for Play Store compliance and tested across 15+ Android OS versions common among NYC's device-diverse user base.
Cross-Platform Development
We ship one codebase to both iOS and Android with Flutter/React Native, cutting build time by roughly 30-40% versus separate native builds — the choice most NYC startups make racing toward a funding milestone.
App Modernization for NYC Legacy Systems
We migrate aging codebases (Objective-C to Swift, Java to Kotlin) and re-architect performance bottlenecks for finance, media, and logistics apps already live in market.
AI-Powered Mobile Apps
On-device processing with Core ML/TensorFlow Lite, paired with cloud-hosted LLM endpoints — smart recommendations, conversational interfaces, and predictive workflows layered onto your app.
PWA & Web App Development
Progressive Web Apps built on Next.js and Node.js with offline functionality and push notifications — mobile-grade performance without app store friction.
OUR
INDUSTRIES
Industry-Specific Mobile App Development for New York Businesses
Fintech & Wall Street Tech
Multi-factor authentication, real-time transaction tracking, and Plaid/bank-grade encryption from day one — designed to meet PCI-DSS and SOC 2 expectations from the first sprint.
Healthtech (HIPAA-Aware Builds)
Telehealth, appointment scheduling, and EHR-integrated apps with HIPAA compliance built into the architecture, not treated as a checklist.
Real Estate Tech (PropTech)
Listing platforms, virtual tour integrations, and CRM-connected apps with geolocation search and saved-listing features standard in every build.
Media & Publishing
Fast, ad-optimized, subscription-ready apps — paywall logic, push-notification engagement, and content recommendation features.
E-Commerce & DTC
Mobile storefronts with one-click checkout, Stripe/PayPal/Square integrations, and real-time inventory sync.
Logistics
Fleet-tracking, route-optimization, and order-management apps — the same category where we cut one NYC client's crash rate from 8% to under 0.5% after a Kotlin rebuild.
SECURITY
&
COMPLIANCE
US Compliance & Security StandardsWe Build Into Every App
Compliance isn't an afterthought we bolt on before launch — it's part of the architecture from day one.
Privacy & Data Governance
HIPAA • CCPA • NY SHIELD Act • GDPR • COPPA
Financial Transactions
PCI-DSS • 3D Secure • EMV • NYDFS 23 NYCRR 500
Enterprise-Grade Security
SOC 2 Type II-aligned • OWASP MSTG • Encryption at rest & transit • RBAC
Deployment & Accessibility
App Store & Play Store compliance • ADA & WCAG guidelines
Why this matters for New York specifically: the NY SHIELD Act imposes stricter data-security obligations on any business holding New York residents' private information, regardless of where the business is headquartered.
