About this app

RelayBox is a cross-platform sync hub that connects your phone, desktop, and web into one unified workspace.
It provides real-time message and file synchronization, Android notification mirroring, and media status viewing with remote controls.
With offline caching and incremental re-sync after reconnection, your data stays consistent across devices.
In short: RelayBox makes multi-device workflows smoother, faster, and easier to manage.
