### 5/5 — Excellent

*2022-03-09, version 2.1.1*

For all surgical doctors you must have it on your pocket .

### 1/5 — Failed op on i phone 4s

*2019-03-09, version 2.1.1*

The app downloads on i phone 4s running ios 9 but does not go beyond the opening display.

### 2/5 — アプリ自体の安定性に難

*2016-08-26, version 1.3.3*

診断から治療まで、良くまとまっており、胆管炎や胆嚢炎の診療に非常に有用でした。
ただし、アプリの安定性が悪く、何回か戻るボタンを押すと上下のスライドが出来なくなります。その度に、アプリの再起動せねばならず、その点では非常にに使い勝手が悪いです。

### 5/5 — TG13日本語版

*2013-06-13, version 1.3*

日本語版にup dateされていました。ますます、使い勝手向上。
表紙も日本語版もあることを明示して頂けると、日本のユーザーがもっと増えるのでは？？

### 5/5 — 最高です。

*2013-05-20, version 1.3*

よくできてるし、便利でとても使いやすいです。

### 1/5 — Flow chartだけLand scapeで見難いです。

*2013-02-05, version 1.0*

他のページが全てPortraitなのにFlow chartだけLand scapeで見難いです。他のページがLand scapeでリフローしてくれればまだ見易いのですがPortrait固定なので使いにくいです。
