Mobile Capabilities

Engineered for the Palm of Your User's Hand

From instant biometric authentication to native camera pipelines and offline background data sync, we deliver mobile experiences users love.

CROSS-PLATFORM

React Native & Expo SDK 52

A single, battle-tested TypeScript codebase powering both iOS and Android applications. Native bridges provide direct access to the latest platform APIs while maintaining exceptional engineering velocity.

  • Over-the-Air (OTA) instant runtime updates via EAS
  • New Architecture (Fabric renderer & TurboModules)
  • Direct native Swift and Kotlin custom module bindings
OFFLINE CAPABILITY

Offline-First & SQLite Sync

Your app should never freeze or show a blank screen when network connectivity drops. We engineer local encrypted SQLite and WatermelonDB stores that sync cleanly with the cloud when connections restore.

  • Encrypted SQLCipher storage for sensitive user data
  • Deterministic conflict resolution algorithms
  • Sub-millisecond query execution on device
DEVICE HARDWARE

Native Device Hardware & Sensors

Harness the full physical capabilities of smartphones. Face ID / Touch ID biometric logins, custom camera capture filters, background GPS geofencing, Bluetooth Low Energy (BLE) peripherals, and haptic feedback.

  • Face ID / Fingerprint biometrics & Keychain storage
  • Camera barcode scanner & real-time video capture
  • Low-battery background GPS tracking and geofencing
MONETIZATION

In-App Purchases & RevenueCat

Seamless integration with Apple StoreKit 2 and Google Play Billing. We implement paywalls, introductory discounts, subscription upgrades, cross-platform entitlement syncing, and automated receipt validation.

  • RevenueCat integration with unified cross-platform paywalls
  • Cryptographic server-side receipt validation
  • Compliant restore purchases & subscription renewal handling
ENGAGEMENT

Push Notifications & Retention

Re-engage your user base with personalized, actionable push notifications. Using Firebase Cloud Messaging (FCM) and Apple Push Notification service (APNs) with rich media embeds and deep-link routing.

  • Deep-linking into exact screens and transaction states
  • Interactive notification action buttons (Reply, Approve)
  • Targeted user cohort segmentation and delivery scheduling
STORE COMPLIANCE

Guaranteed Store Approval

We take the stress out of app store rejections. We handle certificates, privacy nutrition labels, Apple Privacy Manifests, Google Play data safety forms, and direct submission communication.

  • 100% adherence to Apple App Store Review Guidelines
  • Fastlane automated build generation & TestFlight distribution
  • Privacy manifests & third-party SDK signature audit
Mobile Tech Stack

Engineered With the Best Mobile Tools

We deploy modern mobile engineering stacks that ensure longevity, rapid release cadence, and optimal hardware performance.

Development Lifecycle

From Concept to Live Store Downloads

A battle-tested 4-step mobile engineering roadmap that eliminates guesswork and delays.

01

Mobile UI/UX Prototyping

High-fidelity interactive Figma flows tailored strictly to iOS Human Interface and Android Material Design standards.

02

Cross-Platform Build

Clean TypeScript engineering with React Native or Flutter, setting up offline SQLite caching, responsive screens, and native modules.

03

Real Device QA

Testing across physical iPhone and Android test matrices to verify battery efficiency, 60fps animations, and zero memory leaks.

04

Store Launch & Sign-off

Automated Fastlane deployment, App Store and Play Store review submission, and live release monitoring with OTA capability.

Frequently Asked Questions

Cross-platform frameworks share 85-95% of business logic and UI code between iOS and Android. This drastically lowers initial development costs, reduces ongoing maintenance overhead by half, and allows new features to launch simultaneously on both stores with true 60fps native performance.

We architect our apps with an offline-first paradigm using local SQLite and encrypted key-value caches. Actions taken while offline are saved to an idempotent local mutation queue that automatically synchronizes with your cloud backend once a connection is detected.

Yes. We have a 100% first-time approval track record. We guarantee compliance with Apple's strict privacy manifests, in-app purchase requirements, data collection declarations, and account deletion rules.

Yes! With Expo Application Services (EAS) Over-the-Air (OTA) updates, JavaScript bundle fixes and UI updates can be deployed directly to your users' devices within seconds, completely bypassing the 24-48 hour app store review cycle for non-native binary changes.

We test across physical device suites ranging from compact budget Android handsets to the latest iPhone Pro Max models, validating notch handling, dynamic island integration, tablet responsiveness, and landscape orientation.
