The 9 Bar Society

Bought that bag again? Your last dial-in is already there. Time your shot, log your grind, lock it when it's right, skip the throwaway shots next time.

A logbook for home espresso.

Every new bag, the first few shots go down the sink while you find the grind. The 9 Bar Society helps you waste fewer of them. Time your pull, log your grind setting, save the dial-in when the shot is right. Buy that bag again three months later and your last dial-in is already there.

What's in it · Scan a new bag, save it to your shelf · Built-in shot timer for machines without one · Log grind setting and shot time when something changes · Save the dial-in when the shot is right · See your full history per bag and per grinder · Track when your grinder needs a clean · The app changes colour with your roast. Light tan for a city roast, deep brown for an Italian. A small thing. Pleasant. · Export your data any time, it's yours

What's next · In a future release: shared grind settings between users with the same grinder and the same beans. Scanning a bag a fellow owner of your grinder has already dialled in means their setting is waiting for you. Opt-in, anonymous, only for grinders with numbered reference settings.

What's not in it · No accounts to fuss with. Sign in with a magic link. · No streaks, badges, levels, leaderboards. · No social feed, no follows, no comments. · No ads. No tracking beyond what the app needs to run.

Built in Reykjavík by a home barista who got tired of binning beans.

Every bag is someone's hard work. Respect it.
