## What is Mayu?

Mayu is a wellness app that keeps your meals, fasting hours, workouts, how you feel and your weight trend in one place, so you can look back on your own routine.

Photo-based meal logging, fasting hours, running logs, condition check-ins and a weekly report make today's changes easy to see. As your logs stack up, your Mayu character grows with you, and the rhythm that fits you gets easier to keep.

Made for you if
- You want to log what you eat, but counting calories is a chore
- You step on the scale and still do not know what to change
- You want to keep an eye on your fasting hours and your first meal
- You are worried about regaining after losing weight
- You give up after a few days whenever you start on your own

What you can do

Meal photos and nutrition estimates
One photo of your food lays out estimates for calories, protein, carbs and fat. You get a food diary without searching for every item and typing in grams, and you can correct any estimate yourself.

Mayu score for the day's balance
Instead of judging a single meal, Mayu shows the balance of your whole day as a reference score. You can see what was missing and adjust at the next meal.

Fasting hours and first meal
Mayu logs the hours between your last meal and your first meal the next day. Set a target and the time you have left stays in view.

Running and activity
Mayu estimates the calories you burn as your condition changes, and looks at protein and activity together, from the point of view of holding on to muscle.

Weight and condition trends
You see a trend rather than one day's number. Add progress photos and you can watch the change with your own eyes.

Evidence-based AI coach
Ask a question and the coach answers from reviewed material and shows you the source. It does not diagnose you and does not make decisions about medication, and it points you to a professional when that is what you need.

Weekly report and summary
Your week of meals, fasting, activity, weight and condition on one page.

Group logging with friends
Check in on each other's logs in a group room and keep a challenge going.

Mayu, the character that grows with you
As your logs stack up, Mayu hatches from an egg and grows one step at a time. One more reason to log today.

Apple Watch and the Health app
When you work out with Apple Watch, you can see your heart rate and pace on your wrist, and finished workouts are saved to the Health app.

LiDAR deep scan
On iPhone models with LiDAR, point the camera at your plate to measure the food's volume, and that value is used alongside the estimate.

Premium logging and reports with Mayu Care
The Friend plan covers the core logging features. The Care subscription opens up deeper reports and coaching. See the details in the app.

Created by clinicians, reviewed by two doctors
Mayu's coaching standards and content are designed by clinicians and cross-reviewed by two doctors. Only research that has passed review is cited.

Please note
Mayu does not diagnose, treat or prescribe, and it does not replace medical judgment. It does not measure body composition or muscle mass. Always talk to a healthcare professional about your health, your medication and your dose. This service is for adults aged 19 or older.

### 5/5 — 작심삼일을 넘어서게 해준 앱

*2026-08-07*

다이어트 매번 작심삼일로 눈물을 흘렸었는데, 기록하는게 재밌기도 하고 캐릭터들도 기여워서 ㅎㅎ 재밌게 빼고 있습니다. 단톡방 기능이 특히 좋은거 같아요!!

**Developer response:** 후기 남겨주셔서 감사합니다. 작심삼일에서 멈추는 지점이 마유를 만들 때 가장 많이 생각한 부분입니다. 혼자 참기보다 기록이 쌓이고 캐릭터가 함께 자라는 구조로 설계했습니다. 그룹방도 계속 다듬어 나가겠습니다. 있었으면 하는 기능이 있으면 support@habitushealth.app으로 알려주세요 :)

### 5/5 — 간편하게 관리할 수 있어서 좋습니다.

*2026-08-05*

약봉지 스캔이 특히 좋네요. 간단하게 촬영해서 기록 관리하는 방식이 직관적입니다.

**Developer response:** 후기 남겨주셔서 감사합니다. 약 기록은 매일 반복되는 일이라 입력하는 수고를 줄이는 데 초점을 뒀습니다. 촬영 인식이 어색하게 읽히는 경우는 계속 보완해 나가겠습니다. 그런 사례가 있으면 support@habitushealth.app으로
알려주시면 개선에 반영하겠습니다 :)

### 5/5 — 찰칵 😊 사진 👌 만으로 업로드 하면 모든걸 말해준다. 짱 👍편하다  ^^ 게임처럼하는 다이어트 앱.

*2026-08-05*

긴 글 안 써서 너무 편리한 편리한 앱. 😊 사진만 업로드하면 건강체크  비만체크 오케이👍  바쁜 현대인의 시간도 아껴줌 👍아주 편리함. 아이콘도 너무 귀여워죽겠음. 
암튼 이 앱은 사진찍기만 하면 됨. 진짜 편한 다이어트 시작.추천합니당.

**Developer response:** 후기 남겨주셔서 감사합니다. 긴 글을 쓰지 않아도 기록이 남도록 사진 한 장에서 출발하는 흐름으로 만들었습니다. 아이콘과 캐릭터도 하나씩 다듬고 있습니다. 추천해주신 마음 잘 받았습니다. 쓰시면서 아쉬운 점이 보이면 support@habitushealth.app으로 알려주세요 :)

### 5/5 — 너무 좋은 앱이네요...!

*2026-08-03*

다양한 기능들이 많아서 좋은데, 처음에는 살짝 헷갈려서 튜토리얼이 있으면 좋을 것 같아요...!! 비만치료제 복용 중 다양한 걸 복합적으로 볼 수 있어서 좋을 것 같아요!

**Developer response:** 후기 남겨주셔서 감사합니다.

처음 사용할 때 흐름이 헷갈린다는 점은 개선 과제로 등록했습니다.
첫 실행에서 기록 순서를 안내하는 화면을 준비하고 있으며, 정리되는 대로 업데이트에 반영하겠습니다.

여러 기록을 한 화면에서 함께 보는 부분은 계속 다듬어 나가겠습니다.
그외에 불편한 점이 있으면 support@habitushealth.app으로 알려주세요 :)

### 5/5 — 다이어트 앱

*2026-08-03*

사진만 찍으면 알아서 인식해서 식단 정리해주니까 너무 편하고 다마고치 같은 느낌이라 재밌어요!!

**Developer response:** 후기 남겨주셔서 감사합니다.

사진 한 장으로 식단이 정리되는 것과 기록이 쌓일수록 마유가 성장하는 것, 두 가지가 마유의 핵심 설계입니다. 
두 부분 모두 계속 다듬어 나가겠습니다 :)
