Cross-platform mobile app development using Flutter, React Native and Ionic. From concept to app store deployment, for iOS and Android.
Flutter apps with consistent UI across iOS and Android, built from a single codebase with a fast development cycle.
Cross-platform React Native apps for teams with JavaScript experience, with code reuse and a broad library ecosystem.
One hybrid app that runs on both iOS and Android, reducing the effort of maintaining two separate native codebases.
Mobile interfaces designed around user flows, with platform guidelines considered so the app feels familiar on each device.
Integration with payment gateways, third-party APIs and backend services, including Firebase and custom REST APIs.
Post-launch support covering bug fixes, OS updates and feature enhancements, with support terms agreed in the contract.
Based in Delhi NCR, we build cross-platform apps that are practical to maintain, easy to scale and built around your business goals.
We work with both Flutter and React Native, and recommend the framework that fits your project requirements and team.
A single codebase means less duplicated work across iOS and Android, which can help keep development focused and manageable.
Cross-platform development can shorten the path to launch, so you can test your idea with users sooner.
We optimise rendering, memory use and bundle size, and use native modules where a device feature needs platform-specific code.
Apps are structured so new features, screens and users can be added without rewriting the core application.
Ongoing support keeps your app updated for new OS versions, secure and responsive as your user base grows.
A six-step process from requirements to launch and ongoing support.
We review your business goals, target users and app requirements to define scope, features and timeline.
Wireframes and mockups show the app structure and user flows before development begins.
The app is built with Flutter or React Native, with regular builds and reviews throughout the sprints.
Testing across iOS and Android devices covers functionality, performance and usability before release.
We prepare builds and store listings for the Apple App Store and Google Play, and handle the submission steps.
After launch, we monitor the app and provide updates, bug fixes and feature enhancements as agreed.
Frameworks and tools we use to build cross-platform mobile applications.
Flutter is a good fit for apps that need a consistent UI across platforms. React Native suits teams with JavaScript experience and an interest in its ecosystem. Ionic is often used for web-based and content-heavy apps. We recommend the option that fits your requirements after reviewing them together.
Sharing most of the codebase between iOS and Android reduces duplicated work and makes feature updates easier to roll out on both platforms at the same time.
We look at rendering efficiency, lazy loading, memory use and app size, and use profiling tools to find bottlenecks before release.
Device features such as camera, sensors or specific hardware access sometimes need platform-specific code. We integrate native modules where a cross-platform package is not enough.
Encryption, secure storage, API authentication and permission handling are part of our build process. We also follow Apple and Google store guidelines during submission.
Answers to common questions about our hybrid mobile app development services.
Hybrid app development creates a single mobile application that runs on both iOS and Android. Instead of building two separate native apps, developers share most of the codebase. Frameworks such as Flutter and React Native make this practical, which can reduce development effort, speed up launch and simplify maintenance.
Both frameworks suit hybrid apps. Flutter is known for consistent UI across platforms and rapid development, and is a good fit for visually rich apps. React Native suits teams with JavaScript experience and benefits from a large ecosystem. The right choice depends on your project requirements, which we review during discovery.
Cost depends on complexity, features, integrations and design requirements. Oprezo India provides a fixed-scope quote after understanding your requirements, with no hidden costs and flexible engagement models for startups and enterprises.
Simple apps can take around 6 to 8 weeks, standard apps with several features 10 to 14 weeks, and complex enterprise apps 16 weeks or more. We use sprint-based delivery and share a timeline after the requirement discussion.
Modern hybrid frameworks such as Flutter and React Native can deliver smooth performance for most business apps. Performance depends on code quality and optimisation. Where device-specific features are needed, native modules can be integrated.
Yes. Support can include bug fixes, updates for new iOS and Android versions, performance improvements and feature enhancements. Support terms are agreed in the project contract.
E-commerce, healthcare, education, logistics and finance businesses often use hybrid apps for faster market entry and easier maintenance. Content-heavy apps, social platforms, utility apps and productivity tools are also a good fit.
