### 3/5 — 機能は満点だけど…

*2026-05-28*

カレンダーに使うアイコン(スタンプ？シール？)のデザインが非常にダサい上に無駄に動画タイプなので目がチカチカします。
少しだけアイコンが増えたのは有り難いですが、まだまだ種類が少なすぎてスケジュール管理には使い難いです。
医療やダイエット系だけやたらとあっても使い道がありません…
追加購入すれば少しだけ増えるものの、やはり日常の予定や簡単な日記で頻繁に使いたいアイコンは少ないです。
機能としては凄く良いので、今後のアップデートに期待しています！
是非、静止画タイプで日常生活に使えるアイコンの追加をお願い致します。

### 5/5 — Very useful

*2026-05-19, version 4.15.4*

Been using for many years and it keeps my record whenever I want to refer.

### 5/5 — Very useful

*2026-01-09, version 4.15.2*

Been using for many years and it keeps my record whenever I want to refer.

### 5/5 — Great app

*2025-06-19*

Great app to use , easy to memo, and good tips for women and girls’ period cycle. I love this amazing app!

### 3/5 — 生理予定日が当たるのですが、、

*2025-05-18*

毎月生理がくるのですが、日にちが3日位ずれただけで今までカレンダーで付けていた過去の履歴が全部消されるのやめてほしい！今まで印をつけてた意味がなくなります！
産婦人科など病院で生理日がいついつなど記入する欄などもあるので生理周期がズレても過去の生理日はそのままでお願いします‼︎

### 5/5 — 簡単、便利！

*2025-05-14*

簡単でシンプルな作りが気に入ってて、10年近く使ってます。
カレンダーで簡単に予定を把握出来るし、いつ頃生理が来るかの予想。なんか気分がおかしいな、、と思ってみてみると生理前だったとか良くあります。原因が分かれば「あぁ。だから気持ちが変だったのね」と理解する事で余裕が出るので助かってます。
ホルモンバランスの変動で、精神面や食欲が変わりやすい方に特にお勧め。
分かってるだけで安心します。

### 5/5 — これが一番好きです

*2025-04-28*

別の有名アプリも併用していますが、リズム手帳の方が無料で長期データを保存してくれるので、排卵日と生理予測共にこちらの方が精度高いです。 基礎体温の平均値も変動線として表示されるので、排卵日と高温期がパッとわかりやすくて助かります。 絵文字機能などは使わないので、リニューアルがあったら嬉しいです。

### 4/5 — 自覚している周期を変更できるようにして欲しい

*2025-04-20*

5年以上使用していて使い勝手のいいアプリなのですが、周期が変わったため登録内容を変更したくQ&Aを見ると、過去の生理周期全て削除して設定し直す必要があるとのこと。
過去の周期は残しておきたいので、途中から変更できるようにして欲しい。

### 5/5 — Very useful

*2025-02-22, version 4.13.11*

Been using for many years and it keeps my record whenever I want to refer.

### 4/5 — 可愛いカレンダー

*2024-12-25*

生理目的でなく可愛いピンクのカレンダーに惹かれてダウンロード。独身の頃から使っていて妊活にも役立ちました。私は生理は規則正しいので、基礎体温をつけてなくても予測が立てやすかったです。これがなかったら闇雲に妊活してたと思います。
