## What is ooo?

ooo measures your face's left–right symmetry from a single front-facing photo. Take one with the camera or choose one from your library.

■ Overall symmetry score
The left–right difference summed up as a number out of 100 (100 = no measured difference). It measures symmetry only, not appearance.

■ Mirrored faces
Swipe through the original, the flipped photo, and faces made perfectly symmetric from the left half or from the right half.

■ Detailed report
Midline tilt, left–right turn and up–down angle, plus how much higher one side sits at the eyebrows, outer eye corners and mouth corners, shown as percentages and degrees with the direction.

■ Asymmetry pattern
Based on which way the chin is shifted and how the eyes line up, the result is labeled Type 1–3 or Balanced. The type is a name for the measured pattern, not a diagnosis.

■ Live guidance while you shoot
The camera checks distance, centering, head angle, lighting and expression, tells you one thing to fix at a time, and takes the photo automatically once everything lines up.

■ Save and share
Save the photo you're viewing (original, flipped or mirrored) to Photos, or share it.

■ Your photos stay on your phone
Face detection and analysis run entirely on your device. Your photos are never sent to a server, and no account is needed.

ooo is for fun and reference only. It is not a substitute for medical advice.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-10

• Missing features are no longer hidden
If the eyebrows, outer eye corners or chin can't be found in a photo, that row now shows "—" and asks you to retake with your face filling the frame. No type or score is made up from missing data.

• A score only when all four features are found
Partial measurements get no score and aren't saved to History, so your averages and trend stay honest.

### 1.3.0 — 2026-10-06

• New History tab
Your latest score each day is saved. See your trend in daily, weekly, and monthly views.

• Look back at any day
Tap a date to see each feature's left–right height difference and your head angle and tilt.

• Reminder to measure again
Opt in to get a single reminder 7 days after your last measurement. Turn it on or off in History.

• Share without showing your face
You can also choose a result card with just your score and type, no photo.

• Compare with your last measurement
The detailed report now shows how your score changed since last time.

• Delete your records
Remove a single day or clear all your records.

• History saves numbers, not photos
The app deletes its temporary copy of your photo after analysis. Photos are saved or shared only when you choose to.

### 1.2.0 — 2026-09-26

• Now in English
The whole app, from the camera guidance to the report, is now available in English.

• Live guidance while you shoot
The camera watches head angle, distance, lighting and expression, tells you one thing to fix at a time, and takes the photo automatically once everything lines up.

• Mouth corners from the lip outline
Mouth-corner position now comes from the average of four points on the lip outline instead of a single point.

• Smaller differences get an asymmetry type
A mouth-corner height difference of 1.5% or more now gets an asymmetry type showing which way the chin is shifted. Previously anything under 2% was "Balanced".

• Find the app from a shared photo
Saved and shared result images now say how to find the app. Sharing to a messaging app also includes the App Store link.

• Fixed a stripe along the edge of shared photos.
• A few more usage events are now recorded to see where people stop between taking and saving a photo. Photos and measurements still stay on your device.
• The Home Screen name is now "Face Symmetry" (formerly "ooo"), so you can find it by that name in the App Library.

### 1.1.0 — 2026-08-21

비대칭 패턴 유형이 추가됐어요.

• 점수만 보고 끝나지 않아요
  턱이 어느 쪽으로 틀어졌는지, 그 쪽 눈이 올라갔는지 내려갔는지를
  묶어 type1·2·3으로 알려드려요. 그림과 설명도 함께 담았어요.

• 어느 쪽이 얼마나 높은지 숫자로 나와요
  눈썹·눈꼬리·입꼬리를 부위마다 재서 "왼쪽이 2.2% 높음"처럼
  방향과 수치를 함께 보여드려요. 기존 좌우 편차는 어느 쪽인지까지
  알려주는 이 방식으로 바뀌었어요.

• 다른 사람도 찍을 수 있어요
  후면 카메라를 추가했어요. 거울을 보며 촬영해도 돼요.

• 점수가 왜 그렇게 나왔는지 알 수 있어요
  "8.2°만큼 오른쪽으로 얼굴이 돌아갔어요"처럼 촬영 각도를 문장으로
  알려드려요. 고개가 돌아간 채 찍으면 좌우가 실제보다 달라 보이거든요.

• 왼쪽·오른쪽이 헷갈리지 않아요
  사진에 보이는 좌우가 실제 얼굴과 같은 방향인지 표시해요.
  촬영한 사진과 앨범에서 불러온 사진은 기준이 다르거든요.

• 촬영 가이드가 단순해졌어요
  눈높이 가로선을 없앴어요. 그 선에 눈을 맞추려고 고개를 세우면
  실제 눈높이 차이가 지워져서 유형이 다르게 나왔어요.

• 맞춘 중앙선이 점수에 그대로 반영돼요
  직접 옮긴 중앙선으로 점수와 부위별 수치를 다시 계산해요.
