Mobile App Development in Manhattan, NY
Pinnacle Codes builds custom mobile app development for businesses across Manhattan and the surrounding NY region. iOS, Android, React Native. Same team, same engineering standards as our web work.
Local team, real availability
We're headquartered in Kenilworth, NJ and serve Manhattan clients with on-site meetings, same-timezone communication, and US-based engineers.
20+ years of experience
Pinnacle Codes is a subsidiary of Smart Technology Plus, LLC — two decades shipping custom software for SMEs.
Fixed-bid or retainer
Clear pricing up front. Quote, contract, invoice, and pay — all in one place. No surprise hourly billing.
Modern stack
Production-grade React Native, Expo, Swift, SwiftUI — the same tech that powers the platforms you use every day.
What we build
iOS and Android apps your users will actually open twice.
iOS, Android, React Native. Same team, same engineering standards as our web work.
01
React Native and Expo
One codebase, both stores, native performance for 90% of use cases. Faster delivery and a single team to maintain it.
02
Native iOS and Android
When performance, OS-integration, or graphics demand it: Swift/SwiftUI and Kotlin/Jetpack Compose by engineers who've shipped them at scale.
03
Offline-first
Apps that work on flaky transit Wi-Fi, in basements, on planes. Local-first storage with background sync when connectivity returns.
04
Push and in-app messaging
Targeted push notifications, in-app messages, deep links. Integrated with your CRM so marketing and support can run campaigns themselves.
05
Analytics and crash reporting
Mixpanel/Amplitude/PostHog for product analytics; Sentry/Bugsnag for crash reporting. Configured at launch, not three months later.
How we work
Our process for Manhattan clients
01
Platform strategy
iOS-first, Android-first, both, web-only? We pick based on your audience and budget, not on what we like building.
02
Prototype on device
Working prototype on real phones by week three. Real touch targets, real animations, real performance numbers.
03
Build and beta
TestFlight and Play internal track from week four. Real users in real conditions before the public launch.
04
Launch and post-launch
Coordinated store submission, launch monitoring, and a 30-day stabilization sprint to catch what the beta missed.
