### 5/5 — 欲しかったアプリ

*2022-05-10, version 1.2*

24時間表示時計＋１針時計のアプリを探すとほぼこれしかない希少なアプリ。
機能もシンプルで欲しい人には欲しいアプリです。
更新が止まって数年経っていますが、製作者様が見ていると望んで要望も出しておきたいと思います。
・広告表示を消す課金要素
　買い切りで出してもらえたら即購入します。
・背景の種類を単色（黒など）出来る様にしてほしい。画像読み込みもあり。
・時計位置を変えられると便利（あれば）
・文字盤のブラックバージョン

このアプリは希少価値の高いアプリだと思うので、今後のiosバージョンでも残ってほしい限りです。
何卒よろしくお願いします。

### 4/5 — It gets the job done I guess

*2020-12-31*

I was looking for a one handed clock app, and this is a one handed clock app. However, I would have liked more options for dial design. The ticks marks on the “one hand 12 hour” dial don’t divid the hour in a meaningful way. There are some options for the background but no simple plain black. Lastly, I would LOVE this as a widget for the Home Screen.

### 4/5 — 幼児向け

*2019-02-23, version 1.2*

60進法がまだ早い幼児に「8時になったから保育園にいくよ」と言うのに向いてます。
以下が要望:
・ストアによるとApp内課金に「広告削除」とあるがApp内で課金画面が見つからない
・iPadに対応して欲しい
・ステータスバーを表示するとレイアウトが崩れる

### 5/5 — LOVE IT

*2017-09-27*

Not a lot of “bells and whistles”, just a simple and elegant one-hand 24 hour clock.  I wish I could get this as an app for my Mac. It is my favorite time keeper.

### 5/5 — Fun!

*2015-10-24*

A cute app that does a neat job of telling the approximate time very simply but very clearly.  A joy to have!

### 5/5 — Great to see someone has done this

*2015-07-31*

I would dearly love to own a real one handed watch (UNO 24).  Until I can justify the $300 + this will suffice and I can get used to viewing the real passage of time over 24 hours.   Thanks for this.

### 1/5 — ハングアップ

*2014-07-23, version 1.0*

10分ほど、放って置いて、文字盤を触ると、ハングアップして、電源も落ちなくなりました。
