What's Included

Mobile Apps That Users Keep

Cross-Platform Development

React Native and Expo for apps that share 90%+ codebase across iOS and Android while maintaining native performance and feel.

Offline-First Architecture

SQLite local databases, background sync, conflict resolution, and graceful degradation so the app works without internet.

Push Notifications

FCM/APNs push notifications with deep linking, notification preferences, A/B testing, and scheduling through Firebase or OneSignal.

Biometric & Secure Auth

Face ID, Touch ID, PIN auth, JWT sessions, and secure keychain storage — enterprise-grade security with consumer-grade UX.

Device Hardware Integration

Camera, GPS/maps, Bluetooth, NFC, barcode scanning, and health kit integrations for feature-rich, hardware-aware applications.

App Store Submission

We handle the full App Store (Apple) and Play Store (Google) submission — screenshots, metadata, review responses, and approval.

How It Works

Our Delivery Process

01

UX & Flow Design

Map every user journey and screen before coding.

Figma mockups for every screen, interaction micro-animations, and a clickable prototype to validate UX with real users before development.

02

Native Development

Build with React Native or native Swift/Kotlin.

Component-first development, native module bridging where needed, and shared backend API development if building from scratch.

03

Testing & Optimization

Comprehensive device and OS testing.

Testing across 10+ device/OS combinations, performance profiling, memory leak detection, and accessibility audit.

04

Store Launch

App Store and Play Store submission and approval.

We prepare all store assets, metadata, privacy policy, and manage the review process. Most apps approved on first submission.

FAQ

Common Questions

React Native is recommended for 90% of projects — you get a shared codebase, faster development, and lower cost while achieving near-native performance. Native Swift/Kotlin makes sense only for apps requiring very specific hardware access (ARKit, advanced Bluetooth), games, or applications where every millisecond of performance matters.
Yes. We handle the complete submission process — creating developer accounts (if needed), preparing store assets (screenshots, app descriptions, metadata), submitting for review, and managing any review rejections. Our first-submission approval rate is over 95%.
We can build the backend API as part of the project, or connect to your existing backend. We commonly use Node.js/FastAPI REST or GraphQL APIs with Firebase for real-time features. If you already have a backend, we integrate with it and document the API contract.
We offer retainer packages for ongoing app maintenance, including OS update compatibility (each new iOS/Android release), feature additions, bug fixes, and performance improvements. We also manage app store compliance and new store requirements as they evolve.
Yes. Offline-first architecture is a core capability. We use SQLite (via WatermelonDB or Realm), background sync with conflict resolution, optimistic UI updates, and graceful degradation for network-dependent features. The app will continue functioning and sync when connectivity is restored.
