### 1/5 — わかりやすいが

*2025-08-06, version 1.1.4*

糖質の結果は表示されますが、表示された数字は客観的に見て高いのか低いのか、コメントが有ればよろしいかと思います。

### 2/5 — 計算値不良

*2021-08-08, version 1.1.4*

カロリーゼロ、タンパク質ゼロ、脂質ゼロ、糖質1.0g、食物繊維5.5g表記のお茶が有りますが計算では糖質0gが表示されます。また、100Kcal、タンパク質4.3g、脂質2.5g、炭水化物15g表記のお粥250gが有りますが計算では糖質15.1gが表示されます。この値では米の植物繊維がゼロになりますがありえないと思います。

### 5/5 — ほんま便利

*2021-02-09, version 1.1.3*

ありがたい

### 2/5 — 微妙すぎる

*2020-10-20, version 1.1.2*

カロリー、タンパク質、脂質、炭水化物の表記は義務化されていると思うのでそこから計算しないと便利ではありません。
炭水化物から食物繊維を引いた数字が糖質なので、最初から食物繊維量がわかるお弁当はなかなかありません。

### 5/5 — 入力した数値が見えない

*2020-02-19, version 1.1.1*

ダークモードだと入力した数値が見えません。
計算はちゃんと出来ているようなので、修正してもらえると助かります。

（追記）
修正ありがとうございます。シンプルで使いやすいので助かりました。

### 1/5 — 不正確？

*2019-08-20, version 1.0.4*

糖質ゼロの食品で計算しても妙な数字？ この方程式の根拠は？  教えてください。

### 5/5 — 助かってます

*2018-05-05, version 1.0.1*

カロリーとたんぱく質と脂質を入力するだけで糖質量がわかり、糖質制限している私には無くてはならないもので とても重宝しています。
