Not supported and known limits

Intel Macs (Kagami needs Apple silicon).

Busy or 2.4 GHz Wi-Fi, VPNs and Low Power Mode can add delay or stutter.

Install

A minute, start to finish.

Mac

Download Kagami from the download page.
Open the file and drag Kagami into Applications.
Open Kagami. If macOS says it couldn’t verify it, click Done, then System Settings → Privacy & Security → Open Anyway.
Allow Local Network (to find your iPhone) and Microphone if you record your voice.

Windows In development

Download Kagami from the download page.
Open KagamiSetup.exe.
If you see “Windows protected your PC”, click More info → Run anyway, then Yes.
Finish the setup. Kagami opens.

This one-time warning is normal for new independent apps. The download page shows every click.

Connect your iPhone or iPad

Pick wireless or wired.

Wireless

Put your iPhone and computer on the same Wi-Fi.
On the iPhone, open Control Centre → Screen Mirroring.
Tap Kagami 鏡.

Wired (USB)

Plug in the cable.
Tap Trust This Computer if asked.
Open Screen Mirroring and tap Kagami 鏡.

The first time a new device connects, Kagami asks Allow / Don’t Allow. Only allow your own devices.

Best settings

For the smoothest picture with the least delay.

On your iPhone

Low Power Mode off

On your computer

Using a cable? An original or MFi-certified one, plugged straight into the computer, works best.

Using Kagami

Picture quality

Chosen when your device connects, so disconnect to change them.

Resolution: Screen Size (best) uses your device’s own resolution. 1920×1080 and 1280×720 are lighter on older computers or busy networks.
FPS: Device Max (best) uses your device’s highest refresh rate. 60, 30 or 25 save power and bandwidth.

Recording

Click Record, or press ⌘R on Mac.

Audio: Phone + your mic, phone only, mic only, or no sound.
Microphone: Your computer’s mic, or any USB mic or audio interface.
Mic volume: 0 to 500%.
Test mic: Hear yourself live. Use headphones so your speakers don’t echo into the mic.
Mic as a separate file: Off: one video with game sound and your voice mixed. On: the video with game sound, plus a second file with only your voice, ready to edit.
Quality: Best quality, or smaller files.
Portrait recordings: Phone screen only, or inside a 16:9 frame with black bars.
File type: MP4 or MOV.
Save folder: Change or open it any time. Kagami shows the file size per minute before you start.

Recordings are saved every 2 seconds, so a crash or power cut keeps everything before it. If your disk is nearly full, Kagami tells you before you start.

Instant replay

Missed the moment? Save it after it happened.

Turn it on in Settings → Recording. Kagami keeps the last 10 minutes ready.
Press ⌃⌥S to save the length you picked: 15 or 30 seconds, or 1, 2 or 5 minutes.
Or press ⌃⌥⇧S and type how far back to save, up to 10 minutes.

Both keys work even inside a full-screen game. Free saves the last minute, Zenn up to 10.

Mic clean-up

Studio-style voice, with no extra plugins.

Noise removal (1×–5×): Fans, keyboards, room noise, even electric hum. Start at 1× and go higher only if needed.
Voice enhancer: A clearer, louder, stream-ready voice. “Depth” adds warmth.
Noise gate: Total silence between your words.
Compressor: Keeps your voice even when you get loud or quiet.
Limiter: Stops your voice distorting when you shout or laugh.

Turn on Test mic to hear the result while you change settings.

Streaming with OBS

A full-quality picture in OBS, even when Kagami is hidden.

In Kagami, open Settings → Streaming and turn on Share to OBS.
In OBS, add a Syphon Client source (Mac) and choose Kagami.
Pick full screen or 16:9.

Prefer Window Capture? Press ⌘K for a clean view with no buttons.

Privacy mode

One key, and nobody sees your screen.

Press ⌃⌥B to cover your screen with a “Privacy mode” card. Your stream, OBS, recordings and replays all see the card. Type a password or open a message, then press it again to come back.

Picture and window

Make it look exactly how you like.

Colour: True iPhone colour, or a punchier look.
Adjustments: Brightness, contrast, colour and sharpness. Can also go into your recordings and OBS.
Smoothing: Smoother edges when the picture is resized.
Looks: Save, import and export your own presets, or reset everything.
Connect animation: Shoji door, Brush stroke, Mirror flip, Ink dissolve, or none.
Window: Full window, phone screen or 16:9. Keep on top. Hide Settings from your stream.

Common questions

Does Kagami put a watermark on my recordings?

No. On Free, a small mark shows only on the live window and in OBS. Your recording files are always clean.

Why did my recording stop at 2 minutes?

That is the Free limit. Zenn records with no limit.

The picture stutters. What can I do?

Turn off the iPhone’s own screen recording and Low Power Mode, use 5 GHz Wi-Fi or a cable, then click Fix next to the delay meter.

If the live window lags, is my recording affected?

No. Recordings are made from the stream itself, so they stay smooth and in sync even if the live view skips a frame.

Do I need to install anything on my iPhone?

No. Kagami uses Screen Mirroring, which is already on every iPhone and iPad.

Where is my mic file?

Next to the video, with the same name ending in “- Mic”.

Does it work with games like BGMI?

Yes. Game sound and your mic are both recorded.
