Your notifications, on every device you trust.

NotiSync mirrors notifications from the apps you choose to your other devices — including replies and action buttons — end-to-end encrypted, with no account and nothing in the cloud that can read their content, sender, or source app.

Why NotiSync

Stay in the loop, without giving anything up

NotiSync links the devices you trust into a private circle. Your Android devices capture and mirror notifications; every trusted device shows them, and notification actions can flow back to the source device — on any network, whether they're on the same Wi-Fi or a world apart. You pick what flows, and nothing else gets out.

End-to-end encrypted

Titles, messages, source apps, sender names, conversation details, and images are sealed on your device. The server is only a courier — it relays ciphertext it can't open.

No account, ever

No sign-up, no password, no email address. Your devices trust each other directly — there's no profile for anyone to mine.

Pair your devices

Scan a QR code, tap nearby devices with NFC, or share the pairing link. Verify the safety number before trusting, with no server deciding who belongs.

Choose exactly what mirrors

Per-app control with a searchable list. Skip ongoing and media notifications automatically, or fine-tune each app yourself.

Act from any device

Use supported action buttons and inline replies from a mirror, tap to open the real notification on the source device, or swipe once to clear it everywhere.

Easy on your battery

Built around platform push systems, with optional batching for low-priority alerts to cut radio wake-ups, data, and notification noise.

Beyond notifications

Advanced tools for devices you trust

Pair NotiSync with your computer to keep long-running work visible, put sensitive approvals on Android, and reach another Android screen. Each tool is opt-in and stays inside your trusted-device circle.

Screen Sharing

Android, iOS & Desktop

Experimental

See and control a trusted Android device from NotiSync on Android, iPhone, iPad, or desktop. Connect directly or use an end-to-end encrypted relay. Requires Shizuku in ADB mode on the device being shared.

Run

Android + Linux/macOS

Launch a command with nsrun, then follow its output and control it from NotiSync on Android. Answer supported prompts or stop the process when needed.

Seal

Android + Linux/macOS/Windows

Review and approve OpenPGP-signed Git commits in NotiSync using a private key managed by OpenKeychain on Android. The signing key stays off the computer.

SSH Agent

Android + Linux/macOS/Windows

Use NotiSync as the SSH key provider for standard ssh and ssh-add on Linux, macOS, and Windows. Keep keys and approvals on Android.

Desktop note: NotiSync Desktop requires JDK 21. Run and desktop Screen Sharing are currently included on Linux and macOS; Seal and SSH Agent pair Android with Linux, macOS, or Windows.

iPhone Bridge & App

Works with and on iPhone

Pair your Android device with an iPhone via Bluetooth and NotiSync will sync your iPhone notifications across your devices.

The iOS app is not required for the ANCS bridge; install it when you also want that iPhone or iPad to receive mirrored notifications and manage filters.

How it works

Up and running in three steps

No accounts to create, no servers to configure. Just install, pair, and choose.

Install the app

Install NotiSync on the phones and tablets you want to keep in sync. Android is available on Google Play; iPhone and iPad are available on the App Store for iOS/iPadOS 18.6 or later.

Connect your devices

Scan the pairing code or tap with NFC to form a trusted, private autonomous group. Verify the safety number and you're set.

Optionally, connect your iPhone to share notifications from it.

Pick your apps

Choose which apps mirror. From then on, their notifications appear on your other devices — encrypted end to end, with supported actions sent back to the source device.

Private by design

The server is a courier, not a reader

NotiSync was built so that the people running the service — including us — cannot read your notification content or private notification details, including source apps and conversation senders. The encrypted body is for your devices only, using hardware-backed keys that never leave them.

The relay still needs device-routing information to deliver a wake-up to the right place, and it keeps that for the shortest time it can. Notification details stay sealed.
