  • .NET 10 / WinUI 3
  • Kotlin / Jetpack Compose
  • TLS 1.3 + SPAKE2/P-256

Why you cannot download yet

Our builds are finished and gated, but they are not yet signed with a publicly-trusted certificate. Windows would present them as an unknown publisher. We are not shipping software that teaches you to click past the warning that protects you. Releases open the day signing is in place.

Why we built it

Other apps do this. Every one we tried either made it complicated or stopped short of the thing we actually wanted.

  • The phone on the big monitor, straight away.
  • Usable once it got there, not just a picture of a screen.
  • No cable ceremony every single time.

So we built the short version. Pair it once. After that it is one tap from either device.

What it does

Your phone, on your monitor, driven by your mouse.

Use the phone from your desktop The mirror is live rather than a picture. Your mouse and keyboard drive the handset, so you can select and copy text off the phone, type into it with a full size keyboard, and capture its screen with whatever screenshot tool you already use.
Pair once, then forget the cable Connect over USB or Wi-Fi to pair. The app remembers the handset and its wireless address, so from then on it reconnects by itself. The cable was a one time step.
Start it from the phone A button on the handset casts straight to your monitor. You do not have to walk over to the desktop and open anything first.
Your network only It binds to private interfaces. No internet relay of any kind. Your screen never travels through somebody else’s server.
Paired, not accounted Password authenticated key exchange over TLS 1.3, with the trust store encrypted on disk. There is no account to create and nothing to sign into.

Known limit

Mirroring currently runs through a developer stopgap path. The first party media pipeline is the next milestone.

Known limit

Live QR pairing and phone tap acceptance are still waiting on owner sign off.

We list these because you will find them anyway. A limitation you learn about after paying is a defect in how we sold it to you.

Requirements
System Windows 11
