TL;DR

I built a super simple timer app with a few useful features, such as adjustable opacity and click-through support.

Why I built it

A Time Timer-style visual timer is my go-to tool when I’m working or studying. It helps me stay focused and keep track of time much better.

I usually bring a physical timer with me when I work or study outside, but it is quite annoying because I’m really forgetful. So I thought it would be much better to have something similar app on my macbook.

After trying several Time Timer-like apps, I found that all of them had one major issue: visibility.

The visual aspect is the biggest reason I like this kind of timer, so it becomes totally useless if the timer gets hidden behind the app I’m working in. Some apps support an “always on top” feature, but I don't like them because the timer covers part of my screen, and my screen is already small enough.

That’s why I built this app.

It supports a small overlay timer window, and you can adjust its opacity. You can also click through the overlay and interact with whatever is behind it. Click-through is enabled by default, but you can disable it if you prefer.

Caveat

I don’t intend to make money from this app. I built it purely for personal use, so I’m not enrolled in Apple’s Developer Program, which costs $99 per year.

Because of that, macOS may block the app the first time you open it. You can allow it manually in:

System Settings → Privacy & Security

Where to download

Below is the github repository where you can download the app.
