### 5/5 — 気まぐれでも続けやすく愛用

*2025-09-23, version 6.4*

簡単にメモれて振り返りもできて愛用してます。自分の気分の状態が長期にわたって振り返れます。感謝

### 4/5 — 双極性障害の体調変化に活用

*2025-09-17, version 6.4*

睡眠、体調、気分、行動などの変化が一目でわかるようになるので病気の波の可視化に利用しています。

### 5/5 — これからもずっと使いたい。、

*2025-09-08, version 6.4*

もっといろんな人に使って欲しい！使いやすいし見やすい！気分の浮き沈みが激しく、自分の明るい時、暗い時の状況を知るために始めました！振り返れてとても良いです☺︎

### 5/5 — 睡眠時間が複数書けるのが最高です

*2025-08-20, version 6.4*

平日は異常な早起き、休日はトイレや食事以外の時間は起きていられない細切れの長時間睡眠…という傾向の過眠なのですが、他のアプリは入力が簡単でも睡眠時間は一回しか入力出来なかったりして個人的に不便でした。(平日の昼休み寝てしまったりもあるし…)
このアプリは繰り返し睡眠の記入ができるのでありがたいです。手帳などにログとして書き起こす時にも見やすいのが助かります。

### 4/5 — よき

*2025-07-30, version 6.4*

この記録で気分の浮き沈みがとっても分かりやすくなりました！
忘れっぽいから頑張って思い出して記入する時もあるから睡眠のところは全く使っていませんが‼️とっても役立ってます‼️
でも朝、昼、夜、って大雑把すぎて昼でも夜までの間に気分がぐわんぐわんしてる時もあるから、気分の波を直接線で書けるようにしたら楽かもっ
だいすきです！

### 3/5 — まあまあ

*2025-06-22, version 6.4*

双極で、医者に伝えたい為に、単純に体調だけを記録しています。
簡単なので今のところ続いていますが、忘れる時もあります。
でも、大体は満足していますが…ただ、グラフが見にくい。
棒グラフより、１ヶ月まとめたナミグラフにして欲しかったです。
あと可愛い顔のスタンプとかあれば、続きやすいかもしれません。柴犬とか、花とか。

### 5/5 — 助かります

*2025-06-10, version 6.4*

気分や体調の記録が助かります。
体調のところは症状が自分に合わせて変えられますし、カレンダー表示にしてどれくらいの頻度でその症状が起こったかを見るのにも役立ちます。
リスト表示はメモを一気見できます。

### 5/5 — 使いやすい けど、気分記録する区間をカスタマイズできてほしい

*2025-05-28, version 6.4*

プレミアム課金してます。

👇に対応してくれてるのが大変嬉しい
・ダークモード
・メモ

■要望
気分を入力する区間が今「朝」「昼」「晩」となっているが、自分はそんな頻度でつけるつもりはなく、あくまで「日単位での記録」がしたい。
👉記録する区間の粒度を粗くする機能がほしいです。

### 4/5 — 体調の項目を増やせるようにしてほしい

*2025-05-08, version 6.4*

使いやすくてずっと使っています。
体調の項目が6つだけなので、増やせるようになったらいいなと思ってます。

### 5/5 — 使いやすい

*2025-02-16, version 6.4*

心身の体調の管理がしやすくて、使いやすい
