### 5/5 — 入力しやすい

*2026-08-22, version 2.3.7*

排尿記録、水分摂取量が比較できて見やすい
導尿や自尿などの期別ができて集計できると良いと思う
受診の際に一覧で見せられる様な見やすいフォームで出力できたら良いと思う

### 5/5 — 日記

*2026-07-31, version 2.3.7*

素晴らしいよー

### 4/5 — 排便も記録したい

*2026-07-24, version 2.3.6*

排便量(g)も記録できると嬉しい。

### 4/5 — Works for me.

*2026-07-14, version 2.3.5*

Although the app has ads, they are short and not bothersome.
However, it would be useful when converting results in to a csv file, if an extra comma or two could be added to separate urine from drink rather than have both urine and drinks in the same columns.

### 5/5 — Perfect app post kidney transplant!

*2026-05-06, version 2.3.4*

I’ve just had a kidney transplant and need to carefully monitor my fluid balance. The hospital gave me a load of papers, so was always having to remember to take it everywhere with me! 

This app links to an Apple Watch, and means at all times it takes just seconds to record everything. The app keeps the total so you can easily see how everything is going- it also tells you the last time you recorded urine output which was really important in the first few weeks post surgery as I had to go every hour on the hour, and build up the time slowly due to some issues they discovered during surgery.

Can highly recommend! So so easy to use and either free (with ads) or a 1 off payment of £5.99- bargain! 

Thank you!

### 5/5 — シンプルで便利

*2026-04-26, version 2.3.4*

まずはiPhoneでダークモードがあるのが助かります。
シンプルなUIで簡単に操作出来ます。
後から値を修正するには「更新」というのが必要らしくて日またぎで就寝するケースでは記録に注意が必要だったかもです。
概ね満足です。

### 5/5 — シンプルなのが良いです。

*2026-04-14, version 2.3.4*

満足してますが、データを印刷かテキストファイル形式で出力できたら完璧です。

### 3/5 — Apple Watchでは使いにくい

*2026-02-03, version 2.3.2*

Apple Watchで使用できる排尿アプリを探していました。実際使用してみるとApple Watchのホーム画面にて設置できる場所が限られているのは少し残念でした。
シンプルなアプリなので操作に迷うこともなくとても使いやすいです。
以下の不具合？が気になりました。
1.Apple Watchのホーム画面で雫のマークを押した時にマークは動いているのにアプリが起動しない時が頻繁にあり何度も押さなくてはならない。
2.アプリのグラフで日のところには記録が反映されているのに対して、週と月のところは反映されず記録ゼロのままになっている。
他にないアプリなのでぜひ頑張っていただきたいです。これからも使用させていただきます。

### 4/5 — 使い勝手がシンプル

*2026-01-01, version 2.3.2*

入力も、履歴もシンプルでわかりやすいところが良い。ただ、一度さっていしたら、2度目設定のボタンタップしても、設定画面が、表示されなくなった

### 5/5 — ホント簡単

*2025-12-14, version 2.3.1*

糖尿病の教育入院で尿中Cペプチド検査で、24時間蓄尿検査有るので、1日のトイレ回数やどれだけの量が出るのか測るのにこのアプリが簡単で、Applewatch連動してるのですごく便利
