Synco App: Control your phone
without reaching for it.
The Synco tool links your Android phone and desktop into a single system. Mirror notifications, control media playback, and manage incoming calls directly from your keyboard and mouse, fully offline over Bluetooth or your local Wi-Fi. Get the Synco app from GitHub.
Synco Tool: Uncompromising latency. Total privacy.
The Synco app uses Bluetooth LE and Wi-Fi for every device state transition, notification mirroring, and audio route decision — all locally with zero internet round-trips. Free, open-source on GitHub.
Lowest latency profile. Direct point-to-point connection bypassing local routers.
Standard LAN connection. Seamless state mirroring through your existing home/office router.
Ultra-low power connection for notifications, battery telemetry, and proximity status.
E2EE session verification using Curve25519 (ECDH) & AES-256-GCM. 100% cloud-free.
“Synco gave our leadership team four hours of their week back. It feels like control technology from the future.”
“The real-time notification mirroring and call handling are seamless. I no longer reach for my phone during deep work.”
“Offline-first synchronization that actually works instantly. Zero cloud setup means our corporate security team approved it immediately.”
Why choose Synco over other sync tools?
Looking for an AirDroid alternative, a KDE Connect for Windows, or an open-source notification mirroring tool? Synco covers it free — offline, encrypted, and open source.
Proprietary, cloud-dependent, subscription after the free tier.
Synco is a free, open-source AirDroid alternative that mirrors notifications and transfers files over your local network — no accounts, no cloud, no premium tier.
Powerful, but desktop support for Windows/macOS feels secondary.
Synco pairs with any desktop tool on Windows, macOS, and Linux with a one-line terminal setup and a browser dashboard for monitoring.
Screen mirroring via USB/ADB — not background device sync.
Synco complements scrcpy with persistent Bluetooth LE and Wi-Fi sync: notifications, calls, and media control without cables.
Free tier is limited; messages route through third-party servers.
Synco is an offline Pushbullet alternative — everything stays end-to-end encrypted on your LAN with zero dependency on external services.
Synco is built for notification mirroring, media control, and call handling on Android and desktop. It is a free alternative to AirDroid and a privacy-first complement to scrcpy and Syncthing — download the Synco app and compare yourself.
