### 4/5 — Share Bug?

*2026-03-20*

The image is cut off at the bottom when i try to share the statistics, it doesn’t show BMR or metabolic age at the bottom when i try to make a share image. please fix the sizing so the image reflects all the data points thanks

### 1/5 — 動作しない

*2026-02-15*

動作しない

### 4/5 — マタニティモード欲しい

*2025-02-22*

マタニティで体重増えてしまうのは仕方ないことなのに、赤く表示されるとちょっと落ち込んでしまうのでマタニティモードがあったら嬉しい

### 2/5 — 体脂肪率は測れません。

*2024-02-07*

ジムに通って１年間、目に見えて身体が締まり、筋肉質になり周囲からも「痩せた！」と言われる程見た目も変わりましたが、MASARUの数値は全く変わりません。体重計としての機能はありますが、それ以外の数値は全くのデタラメです

### 3/5 — アプリ単体はすばらしい

*2024-02-01*

アプリ単体では素晴らしいです。
Appleのヘルスケアと同期をしたいのですが、こちらのアプリが、新しいヘルスケアに対応出来ていないようです。
アップデートを要求します。

### 5/5 — 現実と向き合う私の味方

*2023-09-30*

対応する体重計を買えば、Bluetoothで自動的にアプリに記録してくれるので、データの改ざんの余地がなく、ありのままの現実と向き合わせてくれます。UIも私好みの、シンプルで綺麗なデザイン。骨密度など、体重以外はどのくらい正確なのか分かりませんが、一般家庭で使うなら十分ではないでしょうか。

### 2/5 — 問い合わせしても24時間以内に返信来ない！

*2022-05-19*

問い合わせ後24時間以内に返信します！と記載されているのに、何度問い合わせしても一向に返信がない‼️
やはり外国だから？
会社が香港となっているから日本語対応していないから？
商品自体は安くて良いものだと思っていたが…残念‼️

### 2/5 — 文字の打ち込みなんとかしてほしい

*2022-03-11*

た^_^くてんうつときに^_^つ^_^てなるのかいけつしてほしいて^_^す。

### 2/5 — 見づらい

*2022-01-07*

画面の文字が小さく見づらいので改善してほしいです。
あと体調（生理や排便等）を記録できる項目があると使いやすいなと思う。
もしくはもっと他のアプリと連動できたら、そちらに替えたいです。
パッとみて変化が分かりにくく、記録する行動がモチベーションアップにはあまり繋がっていない気がする。

### 4/5 — 色が見にくい！

*2021-10-15*

とても便利なアプリで大変ありがたいのですが、文字が細い小さい色が見にくい。
UDカラーやUDフォントとまでいかなくても、白黒など濃淡のはっきりした色で大きなゴシック文字で表示して欲しい。
画面拡大できないのでつらい。
