Hi Product Hunt! 👋

I'm Martin, a home barista and the maker of lattecoach.

Learning latte art at home, I kept running into the same problem: tutorials show you how a perfect rosetta is poured, but nobody tells you what went wrong in your cup. So I built the coach I wanted: you snap a photo, and lattecoach recognises the pattern, scores it on six criteria, marks the mistakes right on the photo and gives you one clear fix for the next pour (pour height, flow, milk texture, cup tilt).

It's on iPhone, in English and German, and you can try it without an account.

I'd love your feedback on two things:

Do the marks on the photo make it clear what to change?
Which pattern should the coach get better at next?

Thanks for checking it out ☕
