I suspect it's a passion project, or a learning project.

I wrote something similar a few years ago so I could go through the process of making it into the app store. I didn't expect a lot (or any) sales.

(But I probably should have put it up on Hacker News so I could get all kinds of comments like yours.)

It's been said before but I'll say it 1000 times again: the over-saturation of subscription saas is annoying and wholly unnecessary.

new models of business should replace it, or even larger economic policy.

It's $4. How is that a subscription?

I still firmly believe that a microtransaction economy would be great for exactly this kind of use-cases to transform currently broken/predatory business models into viable, affordable services. Using the Lightning Network for such transactions seems obvious to me, though I know the general hatred of HN for Bitcoin and crypto (the latter of which I agree with).

Perhaps we should include tipping?

Higher tips enables new features.

Say you want keys that sound like lasers…well that’s a 25% tip!

The difference is you cannot make it inaudible for people around you whereas you can with using software like this.

I get that, but I don’t consider the keyboard noise a feature - more of a side effect.

My wife might pay for an app that silences my keyboard, though.

I work with headphones on and I really like the sound of my switches. I really want to hear them click while also hear music in my headphones.

No reason to use the app if you are not wearing headphones.
