Recently, I used my programming language knowledge and made my computer Countdown Clock app to let me have an enough rest. It uses HTML, JavaScript and CSS.

I usually take a rest every 45 minutes when I do my things. We know there is a timer app in Windows 8, 8.1 and 10, but it isn’t exist in Windows 7 or MacOS.

My laptop must be apple laptop and I must use MacOS because some software are not compatible on Windows for my schoolwork. I also have some old computers, they are not compatible for Windows 8 or later OS, so I have to use Windows 7 (even Windows XP) on them.

We usually use the timer on the phone. Sometimes, I am unable to use the phone. So I made this app.

If you’d like to download the app, you can find the download link on this page.


我做事情的时候,每45分钟要休息。我们知道Windows 8、8.1和10有计时器功能,但是它在Windows 7和Mac系统中没有。

由于一些学习任务的所需软件与Windows系统不兼容,因此我的笔记本电脑必须为苹果电脑,且要使用Mac系统。我也有一些旧电脑,它们与Windows 8或更高版本的系统不兼容,所以我只好使用Windows 7(甚至Windows XP)。
