>In a world where everyone can cook, why would anybody buy prepared food?

I would guess for convenience and saving time. While vibe-coding might be faster, you still have to "do it". As in, think about what you want your software to do, write out or dictate your prompts, test that it works etc. That takes time (might be less time than writing it out by hand but it's still a non-zero amount of time).

I think my comment was misconstrued as siding either way. I didn't communicate it well. It's that it frames questions -- like you were exploring.

Because of course we all buy prepared foods of all sorts from street vendors to fast food to local restaurants to chains to Michelin Stars. While there are many reasons one will cook for themselves, there are many reasons one will buy from someone else too.

Thanks a lot. I'll have to check out Tetris Effect, but pieces becoming and staying invisible sounds really hard. It's plain HTML, CSS and JS. It was a simple enough app that I felt that no framework was needed :)

Thank you :)

Thank you. Glad to hear you enjoyed it :)

Hi HN,

I built MA Weight because most weight trackers show noisy day-to-day changes. I built MA Weight to focus on the actual trend. I’ve used apps like MyFitnessPal to log my weight, but the lack of trend analysis made it frustrating.I also couldn’t find any good option that works on the Web without having to download an app.

MA Weight is a simple web app that smooths out daily fluctuations using exponential moving averages, so you can see your actual progress over time.

Key features:

No sign-up required to start using it

Trendline based on exponential moving average

Manual entry (no device syncing needed)

Import/export your data

Optional login to access your data across devices

Would love to hear what you think or how you’d improve it!

Thanks!
