Why Choose WebBits for App Development?

Native, Cross-Platform & PWA

Swift for native iOS, React Native for iOS + Android, and PWAs when a web-first mobile experience is the smarter move.

Built for Business Outcomes

Booking apps, customer portals, field tools, and companion apps — scoped to the features that move revenue, not vanity screens.

Fast Launch Times

Lean architecture and MVP-ready workflows so you can validate with real users sooner.

Secure & Scalable

Modern authentication, backend integrations, and cloud-native infrastructure that grows with usage.

Senior-Led Execution

Founder-led projects with over a decade of software engineering experience — no junior bait-and-switch.

Maintenance After Launch

OS updates, bug fixes, store compliance, and feature iterations so your app does not go stale six months after launch.

What We Build

From first MVP to production apps your team can rely on day to day.

  • iOS apps with Swift / SwiftUI
  • Android apps
  • Cross-platform apps with React Native
  • Progressive Web Apps (PWAs)
  • Admin dashboards & internal mobile tools
  • Companion apps for existing platforms
  • MVPs for startups and SMBs
  • App maintenance and support retainers

Mobile App Maintenance Services

Launch is not the finish line. We keep apps current, stable, and useful — including apps we did not originally build.

OS & store updates

Keep pace with iOS and Android releases, privacy rules, and App Store / Play Store requirements.

Bug fixes & performance

Crash monitoring, patch releases, and speed improvements so users do not churn on a broken build.

Feature iterations

Small, prioritized releases after launch — without restarting a full build project every time.

Takeover of existing apps

Inherited a codebase from another vendor? We audit, stabilize, and maintain it so you are not stuck.

Frequently asked questions

How much does mobile app development cost in New Jersey?
It depends on platforms, features, and whether you need a native build or React Native. Most business apps start in the mid five figures for an MVP and scale from there. We give a clear estimate after a free discovery call — no vague “it depends” without numbers.
Should we build native iOS/Android or React Native?
Native (Swift) is often best when you need deep Apple platform features or maximum performance. React Native is usually the better value when you need both iOS and Android with one team and a shared codebase. We recommend based on your product, not a one-size stack.
Do you maintain apps after launch?
Yes. We offer mobile app maintenance services — OS updates, bug fixes, store compliance, monitoring, and feature work — so your app stays current after the initial build.
Can you take over an existing app built by someone else?
Often yes. We review the codebase, dependencies, and store accounts, then propose a stabilization plan before adding new features.
Are you a local New Jersey mobile app development company?
Yes. WebBits is based in Union, NJ. We work with businesses across New Jersey and nationwide, with senior-led delivery and office visits by appointment.
