Mobile App Development

We build polished mobile apps with smooth 60fps interfaces that run flawlessly on iPhone, iPad and Android devices. Shellfa delivers both cost-efficient cross-platform solutions and fully native apps for products that demand maximum performance.

Approaches and end-to-end support

• Cross-platform — Flutter and React Native apps: write the code once and run it smoothly on both iOS and Android, saving 40% in cost and time.
• Fully native (iOS & Android) — Swift for iOS and Kotlin for Android, making full use of hardware, Bluetooth, the camera and on-device AI for maximum performance and strong security.
• App Store & Google Play release — support with registering for and passing the strict review processes of the Apple App Store and Google Play Store.
• Feature integration — push notifications, GPS location, in-app purchases and e-wallets.
• Warranty & OS updates — a warranty policy plus free updates for new OS versions (iOS 19+, Android 16+) after handover.
