Mobile App
StarZero
React Native app and React website
StarZero overview
StarZero is a digital product delivered as a React Native mobile app on Google Play and as a React.js website at starzero.org. Users can reach it on the move through the Android app or from any browser on desktop, tablet or phone. The two experiences are designed to feel like one product, with the same identity, structure and behaviour on each.
The project shows the value of a single JavaScript ecosystem across platforms. React Native powers the mobile app and React.js powers the website, so design ideas, logic and even parts of the code can be shared between them. For a growing product, this shortens the time between an idea and a release, because new features do not have to be invented twice.
For users, the benefit is consistency. Someone who first meets StarZero on the website finds the same look and flow in the app, and the reverse is also true. For the business, the benefit is efficiency. A smaller, focused engineering effort can maintain both platforms, and improvements benefit every user at the same time.
StarZero is aimed at users who expect a consistent experience whether they open the product on a phone or on a computer. The React Native app suits people on the move, while the React.js website serves those who prefer a larger screen or are visiting for the first time through search. Together they support both discovery and everyday use.
StarZero was built by Sathwara Infotech, a React Native and React.js development company in Ahmedabad, India. We handled the mobile app, the website and the release of the Android app on Google Play. It is a good reference for anyone looking for cross-platform mobile app development combined with a modern React website.

The challenge behind StarZero
Modern products are expected to be everywhere. Users move between phone, tablet and desktop during a single day, and they expect a product to recognise them and look familiar on each. Delivering that with separate native apps and a separate website normally means separate teams, separate code and features that drift apart over time.
For a young product, that duplication is expensive. Every feature has to be designed, built and tested more than once, and every bug fix has to be repeated. Small differences creep in, so the app behaves slightly differently from the website. Users notice and lose confidence, and the team spends its time keeping platforms in sync instead of improving the product.
Speed matters as well. Early-stage products learn from real users, and the faster the team can release and adjust, the faster the product improves. A technology choice that slows every release by doubling the work becomes a real disadvantage, especially when budgets are limited.
The challenge for StarZero was to launch a polished mobile app and a matching website without doubling cost or release effort. It needed a technical foundation that could evolve quickly, keep the two experiences aligned and remain maintainable as features were added over time.
Our solution for StarZero
We chose the React ecosystem for both sides. The Android app is built with React Native and the website with React.js. Both use JavaScript and the same component-based way of thinking, which lets designers, developers and testers work from shared patterns rather than two separate playbooks.
A shared design language keeps colours, typography, spacing and interactions consistent. A user who moves from the website to the app feels at home straight away. Shared logic for things such as data handling and validation reduces the chance of the two platforms behaving differently, and it makes the codebase easier to reason about.
For mobile, React Native gave us a native-feeling Android app that can be released through Google Play with a single, well-tested codebase. For the web, React.js gave us a fast, responsive site that works across modern browsers and can be optimised for search engines and performance.
Maintenance and growth were part of the plan. With common foundations, new features can be planned once and delivered to both platforms, and future iOS support can build on the React Native work already done. The result is a modern, flexible product that is live on Google Play and on the web.
Delivery followed a simple principle: build once, adapt carefully. We agreed the design system early, built reusable components and tested on real Android devices as well as several browsers. That discipline is what lets a small team keep an app and website aligned, and it is the same approach we bring to cross-platform projects for clients.
If you are planning a cross-platform product, Sathwara Infotech can help you choose between React Native, Flutter and native development, and deliver the mobile app and website together.
