### 4/5 — いいものなのでもう一工夫欲しい

*2020-12-10, version 1.3.2*

前のコメントにもありますが、「何時間後が何日の何時なのか」という計算ができるアプリは珍しく重宝しています。
願わくば、時刻等変更する際バーが小さくて指がかぶって見づらい点、「確定」ボタンがない点(キャンセル、リセットだけでなく確定があるとわかりやすいです)更新と言い換えてもいいのですが、100時間後だったら？120時間後だったら？と色々試すのに煩わしさを感じます。

あと余談ですが、機能として他のアプリでもある、何日何時から何日何時まで(or今の時間)で何時間経っているかも計算できるともっと使えると思います。

色々言いましたが、便利なのは間違いないです。

### 4/5 — Works great but missing a few things

*2015-01-02*

I haven't had any bugs or issues, it works great. I would have given it a 5 star if it gives days, weeks, months and years. It only gives days or years.

### 4/5 — シンプルで見やすい

*2014-03-15, version 1.1.1*

時間が1時間単位しかないことを除けば、分かりやすくて使いやすい。日時の時間差を出すより、何日後、何時間後がいつなのか出せて使いやすいアプリは中々見つけられなくて。現在をワンタップで指定出来るのもいい。
