### 5/5 — Fantastic little moon phase app.  Clean interface.

*2026-02-14*

This is a fantastic simple moon phase app.  The sort that one can use to ball park the moons phase to the min, not sec.   Has worked for around a decade, and I hope kept current and updated for iOS 26.

### 4/5 — 長年使っていて、

*2023-05-13*

このまま使えなくなってしまうのではとさみしく思っていたので、バージョンアップがあったことはうれしかったです

美しさ、情報の多さは替え難い

### 3/5 — Untitled

*2022-03-10*

すごく素敵なアプリだと思うのですが、日付指定する時、クリクリ回さないとダメですか？
入力式にして指定した年月日の月をパッと見れるようにして欲しいです。
できるの？私がやり方わかってないだけですか？

### 2/5 — Ads - great

*2021-05-12*

I’ve used and loved this app for the last ...decade? It’s been part of my iPhone ever since the first generation, I believe. Only recently ads have started appearing. I would pay to remove them, but the dev hasn’t responded to any queries about the topic. Guess it’s time to break up. This app and I are both better than that.

### 3/5 — 日付、時間

*2021-02-22*

iPhoneの設定で、文字サイズを大きくすると、日付、時間がめり込むように、見えなくなる。
文字を小さくすると、日付、時間が見えてくる。　目が悪いので、小さな文字では、ニュースが読めないので、大中小の中程度にしてるが、日付、時間が見えないので、その時だけ設定を変えるのが面倒。
なぜ他の項目は変わらずに出てるのに、日付、時間だけ文字の大小に連動してるんだろう。

追伸　直りました。早速の修正、ありがとうございました。

### 3/5 — 良いのですが…

*2021-02-21*

アップデートしたら 当日の月南中 月入りの時刻が分かりません！
改善お願いします。

### 5/5 — 便利

*2021-02-20*

月だけでなく、太陽の運行もわかりやすくてとても便利。
ただ、最近のアップデート後、月の南中と入りが正しく表示されなくなってしまったのが残念。
早急に対応してもらいたい。

### 5/5 — 子どもとみてます

*2020-07-14*

ここのところ梅雨のせいでお月さまを見れないので嬉しかったようです。
七夕の日に祖母が亡くなり、雨でお月さまもみれず。おばあちゃんは暗い空にいったの？と寂しそうだったので、見せることが出来て良かった。

### 1/5 — 広告がなかったかよかったのに

*2020-02-10*

ここ最近広告が表示されるようになって残念です。

### 4/5 — 改良希望

*2019-10-07*

UIなどは非常に見やすくわかりやすいですが
他のアプリを開いて再度戻ると
今日の日付になってしまいます。
設定で切り替えられるようにして欲しいです。
