Should we build a cross-platform app or separate native apps?

For over 90% of business applications, React Native provides identical performance to native Swift/Kotlin at approximately half the development cost and ongoing maintenance overhead.

Do you handle the App Store and Google Play publication process?

Yes. We configure your developer accounts, build signed production release bundles (AAB and IPA), generate compliant metadata and privacy declarations, and guide your app through review approval.

Can the mobile app work offline without internet?

Yes. We build offline-first caching architectures so users can view data and perform actions without an internet connection, synchronizing with your server when connectivity returns.

How long does it take to build a cross-platform mobile app?

A production mobile app typically takes 4 to 8 weeks depending on functional scope, backend API integrations, and the number of custom native hardware modules required.

Who owns the mobile application source code?

You retain 100% intellectual property ownership of the complete source code repository, design assets, and app store listings upon project completion.

Do you offer post-launch maintenance and OS compatibility updates?

Yes. We provide ongoing maintenance arrangements to ensure your mobile application remains fully compatible with new iOS and Android version releases throughout the year.

Live Production Edge

1. The Efficiency of Cross-Platform React Native Architecture

Maintaining two separate native codebases in Swift and Kotlin doubles development time, inflates bug surface area, and stretches engineering budgets. ProgVision utilizes modern React Native architecture with the new Fabric rendering engine and Hermes JavaScript runtime. You achieve near-native 60fps responsiveness across both iOS and Android from a unified, maintainable TypeScript codebase.

Single codebase cutting development and ongoing maintenance overhead by roughly 50%
Near-instant UI rendering leveraging the modern Hermes bytecode engine
Shared business logic and state management across all target mobile devices

2. Offline-First Resilience for Variable Indian Connectivity

Mobile users in India frequently travel through dead zones or low-bandwidth cellular environments. Applications that freeze or display blank error screens whenever connectivity drops frustrate users and lead to uninstallations. We engineer offline-first data architectures where data is cached locally and synchronizes automatically upon network reconnection.

Local caching ensuring the app remains functional without active cellular data
Optimistic UI updates delivering immediate tactile feedback on user actions
Automated background data synchronization once network connection is restored

3. Native Hardware Integration & Biometric Security

Modern mobile applications require deep hardware integration—from camera barcode scanners and biometric FaceID/Fingerprint authentication to background geolocation and Bluetooth sensors. We build secure native bridges connecting your app to device capabilities while maintaining battery efficiency and user privacy.

Biometric authentication securing access to sensitive patient or financial records
Push notification pipelines keeping users engaged with timely updates
Hardware camera access optimized for instant document capture and QR scanning

4. Guaranteed App Store Submission & Policy Compliance

Navigating Google Play Store and Apple App Store review guidelines can be frustrating. Between privacy disclosures, target API level requirements, and in-app purchase rules, apps frequently face rejections. ProgVision manages the store submission process end-to-end, providing compliant privacy policies, screenshots, and technical configurations.

Full compliance with Google Play Store target API level and 14-day closed testing rules
Strict alignment with Apple App Store Review Guidelines and Human Interface Guidelines
Direct support through the submission lifecycle until official store publication
