I have been publishing apps as a solo developer for a long time and every app I've published has been something I wanted for myself. For example, I spent so much time here on hacker news. So I wanted an app for a better experience. So I built my app almost a decade ago. Then people requested me build one for Android, so I built that too. I've similarly built various macOS apps which I use daily for myself.

If anyone is interested, it's called HACK and I am writing this comment from it. Link is in my bio.
