Your iPad, iPhone and Android,
now displays for your Mac.

No app.
Just scan a QR.

Pick “Start a display” from the menu bar and a QR code appears. Point the device's camera at it, and it becomes a display in seconds. The viewer is served from the public domain md.microai.jp, so there are no certificate warnings.

Any device with a browser works — iPhone, iPad, Android, even a spare PC. The URL never changes, so a bookmark or home-screen shortcut (PWA) is the fastest route next time.

The cursor never lags.

From receive to draw in a measured 2–3 ms. A custom WebCodecs path bypasses WebRTC's jitter buffer entirely (100 ms+ on iOS, uncontrollable). Grab a window and the second screen moves with it — the way it should, wirelessly.

Shaky Wi-Fi?
It keeps flowing.

Measured queue delay feeds back into the encoder, stepping bitrate → frame rate → resolution automatically. Keeping latency low always wins; quality gives way only as much as needed. Even on crowded office Wi-Fi, the video keeps moving.

See the numbers for yourself.

Long-press with two fingers for a live stats overlay: fps, latency, active bitrate, queue delay. The readout is burned into the video itself, so it stays visible even in full screen.

Text stays sharp.

A virtual display is generated to match your device's exact viewport — native resolution, no scaling, no stretching, Retina-crisp text. Rotation and going full screen are followed on the spot.

A display you can touch.

Tap to click, one-finger drag to scroll. Flick to scroll with momentum — tap to stop. Long-press and a blue ring signals drag & drop (Android vibrates); release in place for a right-click. While pinch-zoomed, taps map to what you actually see — zoom in and hit small buttons precisely.

Drops? It comes back by itself.

A streaming watchdog and automatic retries keep watch. After a disconnect the display is preserved for 8 seconds — reconnect and it resumes as the same display, window layout intact. A Wi-Fi dip doesn't derail your work.

The relay can't
see your screen.

The secret key lives only in the QR code (URL fragment) and is never sent to the server. Endpoints verify each other with HMAC signatures, and video flows LAN-direct, DTLS-encrypted end to end. All that touches the relay is a few KB of signaling. Suspect the QR leaked? Regenerate the connection URL from Settings with one click — every old bookmark is instantly invalidated.

On networks where a direct path is impossible — tethering, client isolation, cellular — it falls back automatically to an encrypted TURN relay. Even then the relay only carries packets it cannot decrypt: no one but your devices ever sees the screen.

Always the latest version while subscribed.

Yours forever, plus one year of updates.
