So, on the one hand, I want everyone to be able to vibe code all the software they always wish existed and be able to use it and enjoy it.

But, on the other hand, I don't ever want to use anyone else's vibe coded software. Especially if it's non-essential.

And I certainly won't ever pay for it.

On the Mac App Store page [1], I can see the settings panel in a screenshot. In General Settings / Onboarding, there is a toggle switch labelled:

"Show onboarding on first launch", with more text underneath

"Show first-run guide after installation"

I have no choice but to conclude that this app was vibe-coded from snout to tail.

I couldn't find an example/screenshot of how the reminder would appear on the screen

Not in the FAQ but immediately at the top of my mind when I looked at the images: What is the provenance of these pets? Are they AI generated?

github link seems to be broken: https://github.com/petreminder/reminder
