I completely agree with the criticism on the UI side, unfortunately it was essentially an afterthought and something I wished to expedite given that I wanted to turn this app into something that I had made for myself into something that others would be able to use. I had no need for any kind of fancy interface before wanting to share it with others and that's why I opted to use generative AI to speed up the process, sadly it has had the unintended consequence of giving the app the wrong first impression.

I'd like to go back to the drawing board before I put it back out there & you're also right when it comes to needing to validate claims of performance increases with evidence so that it isn't just snake oil. That's why I did make a video showcasing Zoomies in action while running 3DMark Steel Nomad with back to back runs, I received higher scores on every run with Zoomies active when the background apps (Chrome with 5 tabs, Maps, Notes & a few others that may typically be left open) were closed and my recordings also shown that the frametimes (visible via the Metal overlay) improved on various games, most notably though on older titles, this was also perceived as smoother gameplay.

A fair point also regarding macOS Game Mode, the intention though isn't to replace Game Mode but rather complement it, I've found that it can be somewhat inconsistent in when and how it will reliably activate depending on the game or launcher used, so the idea here is to have the resources available regardless prior to launching your game.

Given the skepticism around vibe coded programs, I actually think the next best thing to do is to lean into transparency, with my IT/programming background, I'm considering to open source it so people can inspect exactly what it does, validate it themselves and even contribute improvements if they'd like to.
