### 4/5 — Very greatest app for measuring in 1/1000 second!

*2023-03-16*

I love this practically finest app! I think that it’s got all the coolest bells and whistles, but I feel that this app could use the most perfect English translation from beginning to end, and therefore, can be used for art and sports practice and greatest exercise use!

### 5/5 — Great!

*2022-07-25*

Excellent app.  No fuzz whatsoever and sharp interface.  Just what i needed, a timer with three decimal spots for speedruns

### 3/5 — LAPとスプリット

*2022-01-11*

LAPとスプリットのフォントサイズを揃えて欲しいです

また、見間違えが無いように両者の色を変えられたり

他の方がコメントされているようにフォントサイズの変更が出来るとありがたいですね

ならば、即買いです！

### 1/5 — 勝手にリセットされる

*2021-02-11*

スタートしポケットに入れていて、3LAP目ぐらいで勝手にリセットされてました。
自分のミスタッチと思って気にしてませんでしたが、何度も続きます。
これではモチベーション下がってしまいます。
もう使いません。

### 1/5 — 開けなくなりました

*2020-12-20*

iPhoneから使えていたのに、開けない状態です。
ｏｓは最新版。
何故でしょうか？
早急の回答願います。
開けなくなったので星は1つです。

### 1/5 — 消える

*2020-11-06*

記録スタートして置いておくと開いたときにリセットされている。重要なものを記録している最中ですごく困った。迷惑しました。

### 4/5 — 左下に文字が重なっている

*2020-11-05*

アプリの画面の左下に、ごちゃっと文字が溜まっています。修正をお願いします。
以下、こちらの環境です。
iPhone 7
iOS 14.1
このアプリのバージョンは、恐らく最初のバージョン

### 5/5 — 使いやすい

*2020-10-02*

ラップタイムも計測出来、何よりも１／１０００まで計測出来るのは、有難く、スポーツの計測にも使えて、重宝してます
ありがとうございます

### 1/5 — 動作不安定、勝手にリセットされる

*2020-02-02*

ちゃんと、動作しないから使うことができない。

計測開始してから、他のアプリを開いていると、
1時間もしないでリセットされる。

バックグランドでいいのかカウントされない、
リセットされる。
リセットされるものとされないものがある。
計測中に展開中の一覧から消すとリセットに
なる。
使い方によるが、最大23:59.59まで計測可。

小数点第3位まで、計れるのは素晴らしいのに

お金払って、広告消したけど、不安定。
イライラする。

### 1/5 — 勝手に
