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

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

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.
