Custom UI/UX Design
Full Figma mockups for every screen — light/dark mode, onboarding flow, and micro-animations designed before a single line of code.
60fps Performance
Optimised rendering, lazy loading, image compression, and native transitions — so your app feels instant on every device.
Push Notifications
Firebase Cloud Messaging (FCM) for Android and APNs for iOS — segmented, scheduled, and rich-media notifications.
Security & Data Encryption
JWT/OAuth2 authentication, biometric login, end-to-end encryption, and GDPR-compliant data handling out of the box.
Offline-First Architecture
Local SQLite / Hive database with sync-on-reconnect — your app works even without an internet connection.

Seamless integration with your existing REST or GraphQL API, or we build a scalable Laravel/Node.js backend for you.
