### 5/5 — Exactly what I was looking for

*2026-01-06*

Easy to use. Simple. Exactly what I was needing to track my weight and how I was feeling.

**Developer response:** Thank you for your feedback, Amy TRN! We are so glad the app was exactly what you needed and easy to use for tracking your weight and how you were feeling. Your words mean a lot to us.

### 5/5 — 추가 기능 요청

*2025-12-06*

몸무게 기록할 때 심플해서 제일 손이 많이 가는 어플입니다!☺️ 추가기능이 있으면 좋을 것 같아서 요청드립니다. 이모티콘이 조금 제한적이라 몇가지만 더 추가되었으면 좋겠고, 노트에 내용을
입력한 날짜에는 노트기록했다는 표시가 캘린더 날짜 옆에 조그맣게라도 표시되면 좋을 것 같습니다. 지금은 일일히 눌러서 확인을 해봐야해서 조금 불편한 점이 있습니다.

**Developer response:** 피드백 감사합니다. 이모티콘 추가와 캘린더 노트 표시 관련 제안을 주셔서 감사합니다. 소중한 의견으로 잘 전달하겠습니다.

### 5/5 — 很好

*2025-11-26*

很方便

**Developer response:** 感谢您的反馈！很高兴知道您觉得很方便。我们会继续努力为您提供更好的体验，欢迎随时告诉我们任何建议或意见。

### 4/5 — ﾀﾞｲｴｯﾀｰには超ｵｽｽﾒ❣️

*2025-11-16, version 3.5.0*

ダイエット中は重宝しています😸
カレンダーでその日の体重を確認できて、○週間・○ヶ月前から○kg減った等を確認できるのがとても便利です💕
そしてなりより、広告が執拗に表示されないのが良きです👍🏻💮広告はありますが、動画の広告、大きすぎる（しかも×が小さすぎる）広告は一切ありません‼️なんのでノンストレスです😽
アプリ自体には大変満足していますが、1週間や1ヶ月ごとの平均体重を表示できるようにしていただけるとより一層便利で素晴らしいアプリになると思います。ご検討お願いします。

### 5/5 — 이걸로 10키로 뺏어요

*2025-11-02*

사실 제가 노력해서 뺀거긴
해여 근데 이거 그래프로도 나와서 그래프가 내려갈수도 기분이 조아서 계속 빼게 되더라구요 !!
진짜 좋은데 저 처럼 귀차니즘 심한사람은 추천 안드릴게요 ㅜㅜ
매일매일 하다가 하루 안하면 귀찮아서 계속 안하게 되요 ㅜㅜ 제가 그래서 이 앱을 지웟어요 ㅜ 아 그리고 앱 개발자님 비밀번호 시스템 좋긴 한데 설정으로 없애는것도 만들어 주시면 조을것 가타요!!

**Developer response:** 소중한 피드백 감사합니다! 앱을 통해 목표를 이루셨다니 정말 기쁩니다. 비밀번호 시스템에 대한 의견도 감사합니다. 앞으로도 더 나은 서비스를 위해 노력하겠습니다.

### 1/5 — 一堆廣告

*2025-10-25, version 3.5.0*

爛死了，下載1分鐘立馬刪除，一堆廣告

### 5/5 — 위젯 추가되면 좋을 듯!

*2025-10-19, version 3.5.0*

깔끔하고 유저 친화적입니다. 개선사항을 말씀드리면 위젯으로 쉽게 몸무게를 입력할 수 있으면 좋을 것 같습니다!

### 5/5 — 希望新增功能

*2025-09-26, version 3.5.0*

如果可以從Health 更新資料就更棒了

### 5/5 — 減重的好幫手

*2025-09-24, version 3.5.0*

這是一款間單明瞭的APP，方便每日做記錄。

### 4/5 — 介護記録用に…

*2025-08-28*

母親の介護記録として利用している。
データ的には約10年分あるが、日々の記録ではなく月々の記録なのでチョッと使い方が特殊かもしれない。

グラフも1年あるいは3年に設定してもスライドすることで任意の期間が見られるので、体重推移がわかりやすく便利。
欲を言えばグラフではなく「一覧表」的な表示もあれば過去のメモ欄なども見やすいので、あれば便利だな…と思う。
登録ボタンを押した後もそのまま残っているのが気になった。現状では「上書きしますか？」の確認が出てはくるが、入力内容に変化がない場合はボタンの色を薄めるなどしてほしい。
カレンダー表示にして他の月に移動していっても画面の左下に最後に閲覧した体重がず〜っと表示されているが、この表示も各ユーザーによって表示のオン/オフが出来る様になてばと感じた。

**Developer response:** ご利用ありがとうございます。グラフや表示についてのご提案をいただき、感謝いたします。ユーザーの皆様にとってより便利なアプリとなるよう、今後の改善に役立ててまいります。引き続きご愛用いただければ幸いです。
