Technical Details

Platform Compatibility

Older legacy codes distributed via SHiFT were platform-specific, but that's no longer the case. Gearbox now issues SHiFT codes that are valid across all major platforms. To avoid unnecessary clutter, a platform filter wasn't included in this app to support the platform specific legacy codes. This also means that those legacy codes are not provided in this app's dataset.

Data Management

SHiFT code listings are sourced from publicly published data and manually updated as soon as new codes are announced on Gearbox social media. The app now features an offline-first architecture with Room database for local storage, automatic background synchronization, and smart notification system for new codes.

Offline-First Architecture

Version 1.4.0 introduces a complete offline-first approach with Room database implementation. Users can access all SHiFT codes even without an internet connection, with automatic background sync ensuring data stays current when network connectivity is available.

Notification System

The app now includes WorkManager integration for periodic background sync every 4 hours, with smart notifications alerting users to new active SHiFT codes. The system respects battery optimization settings and only syncs when network is connected and battery is not low.

Note: This app is designed for simplicity and reliability. The manual update process ensures that all codes are verified and accurate, even if it means slightly delayed updates compared to automated systems.

Requirements: Android API 24+ (Android 7.0) with minimum 2GB RAM recommended for optimal performance. Enhanced offline capabilities and notification permissions for Android 13+ devices.
