Hi Product Hunt, I'm Tuna. I make coffee at home every morning, and for a long time the good cups were accidents. Change the grind, get something better, and by the next week have no idea what you actually changed. I never kept a log by hand and it was hard to do so, so I built the one that keeps itself. You log a brew while you brew it: pick the gear and the bean, run the timer, log the yield, rate the cup on acidity, body and sweetness. It takes about as long as the brew does. After a couple of cups it's easy to notice trends in what you like, what you dislike, and make better informed coffee decisions in the future! What's in it: • A guided brew flow with a recipe-driven timer. On iPhone the stage and target weight sit on the lock screen and in the Dynamic Island while you pour. • Pour recipes you build yourself, any number of bloom, pour and pause stages, with a live water curve as you edit. • A bean library that tracks roast dates and freshness, and a passport where every bean you log mints its own stamp, generated on device from the bag photo and details. • Stats: dial-in analytics, freshness curves, a calendar heatmap, a taste radar. • Café visits on a map. • A feed, if you want one. Follow other brewers, comment, and set any entry to public, followers-only or private. Sharing is opt-in per brew and nothing is public by default. The core is free forever on the web and on iPhone. Premium exists and adds the advanced stats, widgets, bean autofill from image, and a couple extra things. Your data stays yours: full export whenever you want, and import from Beanconqueror if you are coming from there. Built solo from the Netherlands. Open to any questions, discussion, or feedback :)
