Show HN: Kopimatic, Brewing Calculator PWA (nealrs.github.io)

Hey HN, I built a PWA to help you brew a great coffee. It's setup for v60 pourovers, AeroPress, drip, and James Hoffman's Iced Coffee recipe.

It's got wakelock support and a 'mocha mode' for thsoe late night brews. No frameworks, no analytics, no referral links -- just a little JS & CSS hosted on GH Pages.

Recipes and calculations are designed for my equipment & tastes, so YMMV.
