### 1/5 — 最近不具合？

*2024-09-13, version 1.1.4*

Bluetoothで記録した体重が保存されない

### 1/5 — 最悪

*2024-09-12, version 1.1.4*

全くBluetoothが反応しない！

### 3/5 — メール見てくれたのか

*2024-08-15, version 1.1.4*

年齢入力出来なかったがメール送ったらできるようになってた♡感謝

### 1/5 — ちゃんとアップデートしてください

*2024-06-16, version 1.1.4*

他にも書かれている方がいますが、初期設定で生年月日が入れられないため使えません。
アップデート4年前って…ストアにアプリを置いている以上ちゃんとアップデートしてください！

### 2/5 — 使いたいのに、年齢が入れられない

*2023-09-07, version 1.1.4*

アプリを入れたのですが、年齢が入れられず、使えません！
どうしたらいいでしょうか？
バグだと思うので修正してください。

### 5/5 — 電池交換でエラー直りました！

*2023-07-28, version 1.1.4*

突然計れたり計れなかったりするようになり寿命かと思いましたが単なる電池切れでした。スマホとの連動も問題ないです。エラーになる方は電池交換試してみてください。

### 1/5 — ごみ

*2023-06-28, version 1.1.4*

ゴミアプリ不具合だらけ

### 1/5 — ずっとバグってる

*2022-02-03, version 1.1.4*

最初の生年月日の設定すらバグっていてできません！笑

### 2/5 — いきなり接続出来なくなった

*2021-10-05, version 1.1.4*

なんでや？

### 3/5 — 筋肉含有量の値が間違っているのでは

*2020-11-16, version 1.1.4*

筋肉含有量として表示されている値は、除脂肪体重から骨量を引いたものになっているようです。
これだと、体水分や内臓が含まれている。
正しくは、除脂肪体重/2がおおよその筋肉量。

いちいちスマホのアプリを開いてから計測しなければデータが受信できない点が不便です。

Bluetoothでペアリングしてなくても受信できるし、ペアリングしてもアプリを開かないと受信できないので、ペアリングの意味が無いと思う。

あと、アプリを開きっぱなしだと、ずっと画面がアクティブでロックがかからない。電池消耗するので、一定時間後に画面ロックしてほしい。
