Sikgu

Mouths at one table

In Korean, sik means to eat and gu means mouth. Your sikgu are the mouths you share a table with: your family. That's why Koreans say hello with “Have you eaten?”, and “Let's grab a meal sometime” means “I miss you.”

Every family has a table

Yours might be Sunday dinner, or the plate someone keeps warm when you're running late. That's the table Sikgu is named after.

But these days

Everyone's at a different table in a different town. Even eating at the same hour is rare.

Nights you wonder

What did Mom do today? Did Grandma have dinner? It's too late to call, and a text alone feels a little empty.

So, one window each

In Sikgu, each person is a window. Open the app and your window lights up, and short clips cross right away between lit windows.

9 PM, family time

Once a day, everyone opens the app together. All the windows light up at once and today's clips cross over to each other. Like sitting around one table again.

See it in motion

Lights come on, curtains open, the lamb talks and snow falls. It's all the real app.

Ways to share your family's day

Open the curtain on their day

Tap a window and the orange curtain opens on the clips that person left. 3, 5 or 10 seconds: no long takes, no editing, just one tap. Below, you can see whether they've watched the ones you sent.

Your voice instead of your face

On days you'd rather stay off camera, switch to Voice. The camera turns off and only your voice is kept. On the other end, your lamb's mouth moves with how loud you speak.

A tree grows, a dog waits by the door

The persimmon tree by the door grows with every clip your family leaves. When anyone leaves a clip each day, a persimmon ripens for every day in a row. Skip a day and the persimmons fall, but the tree stays as it is. Bring your dog or cat into the home too, and let them sit by the door.

Grow it yourself

A street that follows the seasons

In winter snow falls and settles on the roof; in spring cherry petals drift by. On Seollal and Chuseok, Korean lanterns hang beside the door, and on Chuseok night the full moon rises big. Try it yourself with the buttons on the street at the top.

Seollal night, snow on the roof
Spring, cherry petals on the breeze
Chuseok night, a big full moon

What we promise

A home in three steps

  1. Make your home

    One person taps Make our home, then picks what everyone calls them (Mom, Grandma…) and a name for the home.

  2. Show the invite QR

    In Settings, tap Show invite QR. It carries your home's key.

  3. Scan and come in

    Everyone else taps Join with invite QR and scans it. A new window appears in your building.

Questions

My clips aren't crossing over.

Clips cross while the app is open on both phones. Try opening it together at family time. On iPhone, also check the local network setting below.

Can I receive clips with the app closed?

On Android, turn on Receive in background in Settings and new clips are saved even with the app closed. On iPhone, clips are sent and received while the app is open. That's why there's family time.

What if someone hasn't received a clip?

The phone that sent it holds on to it and hands it over the next time both lights are on. Another member who has the clip may pass it along too.

My iPhone can't find the other phones.

Go to iPhone Settings › Privacy & Security › Local Network and turn on Sikgu.

Does it have to be family?

No. Partners, close friends and roommates can share a home too. When you pick what they call you, choose from Family, Friends or Partner.

Can a spare phone stay up in the living room?

In Settings, tap Use this phone as a frame. The screen stays on and its window stays lit, so a new clip plays with sound the moment it's made. In between, recent clips loop quietly.

Does it cost anything?

It's free. No ads and no in app purchases.

What happens when I leave a home?

That home's videos and records are deleted from your phone. Videos that already reached other members' phones stay on those phones.

Turn on your window tonight

One person makes the home and shows the QR. Then open it together at family time tonight.
