### 1/5 — App ads

*2026-08-01*

App ads don’t have a cross or anything else to close them so I can’t really use the app. Don’t install.

### 4/5 — неплохо, но надо доработать

*2026-07-14*

Спасибо за приложение! Однако не всегда открываются реакции, а еще приложение периодически отключается само по себе, особенно когда хочется посмотреть календарь за прошлый месяц

### 5/5 — うんちタイプ占い

*2026-07-05*

いつも使わしてもらっています。めっちゃいいアプリだと思います。ただ1つ入れて欲しい機能があります。それはタイトルの通り、「うんちタイプ占い」です。イメージ像は、一週間ぐらい続けてある日「あなたのうんちタイプは『2日に1回ドバっとタイプ』です!○○をこうすると便秘が解消されて『1日1回スッキリタイプ』になるよ!」って感じです。私はMBTIとか占いとかが好きだし、ウケると思うのでぜひ入れて欲しいです!お願いします🙏

### 5/5 — Величие!

*2026-06-05*

Великое приложение!

### 5/5 — Пожалуйста

*2026-06-02*

Добавьте в следующем обновлении выкладывать в историю фото своих какашечек , что бы делиться с друзьями своей радостью

### 5/5 — четко

*2026-05-22*

все круто, только добавьте пожалуйста фотки чтобы я мог делиться с друзьями

### 5/5 — caca

*2026-05-19*

super cool

### 5/5 — 友人と🎶

*2026-05-19*

友人と楽しく記録してます！
私は便秘気味😂なのですが、友人は超快便✨で、その対比も面白いです。
便秘改善としても、記録することで意識できております。とはいっても、難しすぎず、シンプルなアプリなので、気楽に記録できるのが気に入ってます。
他の方のレビューを見ていて、色が記録できたらいいといった意見などもあったので、それをアップデートですぐに取り入れていたのだなとわかり、とても素敵な制作者様だと思いました。

### 4/5 — うんカレを月間表示対応にして

*2026-05-19*

便秘体質なので記録用に使っています。
トイレで踏ん張りながら手早く記録できるので助かってます。
お腹の調子が悪い時にはカレンダーで前回のうんちを確認するのですが、週を跨いでいると何日空いているのか視覚的にわかりづらいです。
月間カレンダーだったらもう少し見やすくて嬉しいです。


追記:月間表示対応ありがとうございます！分かりやすくて本当に嬉しいです！

### 4/5 — 健康管理とかには興味なくて

*2026-05-19*

・毎日開くアプリなのに「SNSに投稿する」ボタンが毎回出てきて邪魔でテンポ感が損なわれてる。トイレから戻る数秒でうんちを登録したいのに。登録してからSNS投稿するか選べるようにしてほしい
・ここ最近アプデが多くないか？友達とウンチの記録見せ合いたいだけなんだけど
・リアクションにバリエーションがもう少しほしい
