One square per day, the last 6 weeks. A filled square is a day a Clacky update shipped.

What he makes

Clacky started as one tiny idea: what if clicks sounded nice? It launched on 28 September 2026 and grew into a companion app for people who make things on their Mac.

Justinas makes it alone, both the Mac app and this website, and ships weekly app updates.

How he builds

In public

He shares what worked, what didn’t and the real numbers, in his newsletter and on X.

With AI

Justinas is not a Swift developer. He builds Clacky with Claude, and tries every feature on his own Mac first.

With the people who use it

Replies, emails and the feedback page shape what comes next. He reads every message.
