## What is only4us?

The day opens only when all four post.

only4us is a shared journal where up to four people each leave one photo a day. A day opens to everyone only when all four have posted. If even one person hasn't, nobody can see anything.

If the waiting feels a little uncomfortable, that's by design. That small discomfort is why you open the app every day.


■ One photo, one line, once a day

A photo you took today and a short line. That's all.
No filters, no retouching.
You can change your photo or words until the day opens, but once all four have posted and it opens, it can't be edited.
If something all four have already seen changed later, the promise that each day stays as it was would break.


■ 2×2, and your seat never moves

An opened day shows all four panes on one screen. There's no feed to scroll.
Everyone keeps the seat they started in — yesterday, today, and ten years from now.


■ Your days, on a calendar

Tap the date to open a calendar. Days when all four posted show their four panes in miniature; tap one to go back to that day.
Days that never opened stay that way. Only what you posted that day is visible to you; the other panes stay locked.


■ For the days you miss

If you couldn't post, you can still fill that day until the next day.
And once a week, you can say "I'll skip today." You're taken out of that day's count, and the rest can open it.

When every day becomes an obligation, it doesn't last.


■ What's not here

No likes, no hearts, no view counts, no followers.
There are emoji reactions, but they're never counted. The moment you count, you start ranking.
No search, no recommendations, no friend finder. The only ways in are an invite link or a code an adult creates.
No ads.


■ Never more than four

A circle is fixed at four people. No setting or payment can make it bigger.
A fifth seat doesn't exist anywhere in the app.


■ For families

No iPhone? No problem. It works the same on iPad.

Children under 14 can't use Sign in with Apple. So an adult in the circle creates a seat with "Invite a Child" and hands over a code — the child just enters it to join. We never ask a child for an email or phone number.

Creating the seat is the parent's consent, and it can be withdrawn at any time. Once withdrawn, that child can't post. When a child stops using the app, the adult can clear the seat.
Because the parent is already in the same space, there's nothing to confirm outside the app.


■ Look around on your own

Before creating an account, "Look Around First" lets you try the whole app.


■ Optional: Export Without Watermark

Opened days can be shared as an image with an only4us watermark and QR code — once the circle's owner turns it on in Settings. The owner, the adult who created the circle, can turn it off at any time. A one-time purchase removes the watermark for all four. Every feature works without it.


Made for you if:

· You've watched family photos disappear up a busy group chat
· Social media wears you out, but you still want to know how your family's day went
· You want a record just for the four of you, not something to show others

## Version history (last 5 releases)

### 1.3.5 — 2026-11-06

You can now revisit what you posted on a closed day, when not all four posted. Get there with ‹ › next to the date or from the calendar. Only your pane opens; the others stay locked. In the calendar, a closed day shows only your seat color, so it stands apart from open days.

Posts on a closed day can now be read only by the person who posted them, on our servers as well. It isn't just hidden on screen: other members can't download it at all.

Closed days where you didn't post are still skipped.

### 1.3.4 — 2026-11-04

A security update. We updated an internal component so the connection between the app and our servers stays protected. Screens and features are unchanged.

Please update to this version.

### 1.3.3 — 2026-10-13

Simpler. Inviting a new member and turning on Save & Share are now decided by one person, the owner. No more waiting for all four to agree. The owner is the adult who created the circle.

If you pass and then change your mind and post, your weekly pass comes back.

Fixed reactions losing their emoji and showing only colored dots on days with many reactions. The same emoji now sits in one chip, with a seat-colored dot for each person who left it.

### 1.3.2 — 2026-09-25

Settings are easier to read. Status shows as a dot, on/off items are switches, and things you can tap look like buttons.

See where Save & Share consent stands. Settings shows who has agreed and who we're waiting on, and members who haven't answered see a request on their Today screen.

App notices now open in the middle of the screen instead of being cut off at the bottom.

### 1.3.1 — 2026-09-23

열린 날을 이미지로 저장하고 공유할 수 있습니다. 넷만 보던 기록이 밖으로 나가는 일이라, 설정에서 모두가 동의해야 켜집니다.

공유 이미지에는 only4us 워터마크와 QR 코드가 붙습니다. 워터마크 없이 내보내고 싶다면 설정에서 한 번 구매하면 됩니다. 셀 전체에 적용되고, 산 사람이 나가도 유지됩니다. 사지 않아도 다른 기능은 모두 그대로입니다.

패스를 쓴 뒤 마음을 바꿔 올렸을 때, 정족수가 덜 찼는데 그날이 열리던 문제를 고쳤습니다.

카카오톡 등 앱 안 브라우저에서 초대 링크를 눌러도 앱이 열립니다.

보낸 초대 코드를 취소할 수 있습니다.

영어와 일본어를 지원합니다. 기기 언어에 맞춰 앱이 바뀌고, 알림도 그 언어로 옵니다. 한국어 화면은 그대로입니다.
