### 3/5 — iPad

*2023-01-10, version 1.1*

横画面にできないのは改善点だと思う

### 1/5 — asking permission to paste from notes

*2022-10-26, version 1.1*

when i open app it asks permission to paste from notes app??...  it also froze both the time and timer that i was waiting on

### 3/5 — 光のみが欲しいです。

*2022-09-21, version 1.1*

振動をオフにして、光のみにできるようにして欲しいです。

### 4/5 — いつもお世話になってます

*2022-02-18, version 1.1*

自習室で勉強するときなど様々な場面で重宝してます。ただ、改善してほしいところが2点あります。
1点目は、1度アプリを閉じると、アラーム音や振動数などの設定が保持されないところです。毎回設定し直すのが少し面倒です。
2点目は、アラーム音の長さが短いです。一般的なタイマーのようにstopボタンを押したら音が止まる仕様になると尚良いです。
以上の2点の改善をよろしくお願いします。

### 1/5 — The ads are back!

*2021-06-03, version 1.1*

Very annoying. I paid for the software so they would be gone.. now they are back again.. please fix this!

### 2/5 — 購入したのに広告が非表示されない

*2021-01-19, version 1.1*

購入＝広告非表示と考えるユーザーが多いのでは？　買った後で気づき残念です。
値段上げて構わないので広告が非表示できるオプションをつけてください。頼みます…

### 1/5 — Do not trust!

*2020-11-02, version 1.1*

The timing varies from accurate to widely inaccurate. Sometime a minute is a minute, sometimes it’s 30 seconds. Complete junk!

### 5/5 — Perfect for me

*2020-07-30, version 1.1*

I needed an app to remind me to do something by making the phone vibrate periodically - something the iPhone clock will not do. This worked perfectly.

### 1/5 — Terrible!

*2020-04-24, version 1.1*

I couldn't even write a time for the alarm because it kept flashing black and back to the app again and again

### 1/5 — Time is wrong

*2020-02-04, version 1.1*

It doesn’t even keep accurate time - a 5 minute timer goes off after like 2 minutes. How can you get the most important part of a timer ... keeping time... wrong?!?!?
