So, just an advertisement for what you built? As for the apps, what's so great about them? I'm genuinely curious.

With respect to the microphone test site I don't need it as my OS provides everything I need for this and I also don't trust your site (that's just by default for what you're asking to have access or my machine).

As for the speed test, OK? There are far better options that already exist and are fully open source.

Building things that are trivial, or already exist aren't exciting. It's great that you feel you went from MVP to "full feature". But IMO both of these are MVPs as they stand. They're not worth much to anyone but you, most likely.

The final thing I'll say is both of these examples have the vibe coded look. It's just like text, images and audio now: AI content is easy to pick out. I'd gather things will get better, but for now there's low likelihood I'm interacting with these in any meaningful way and zero chance I'm buying anything from sites like these.

These offer nothing but free services. Even if they have a vibe coding feel. The ctr is dismal anyways from HN. Its simply astonishing the rate these allow of development, yet it seems the vast amount of people don't see it. Crazy
