Beta: still dialling in. Tens of thousands of listings across beans, roasters and cafés, and some will pull a bit sour for now. Spot one? Tell us.

Every shot, against the roaster's recipe.

Log what you pull, see how it compares with the numbers the roaster published, and get the grind to try next. Free.

The app's home screen: the bag in the hopper with its grind, the roaster's recipe, last score and shots

How it works

Three steps, every morning

  1. Put the bag in the hopper

    Add the bag you're drinking. The roaster's recipe comes with it, and the app tracks days off roast, how much is left and what each shot costs.

    The shelf: two bags with day off roast, grind, shots pulled and grams left
  2. Pull a shot and log it

    Pick the bag and the roaster's numbers are there to start from, next to your last shot. Dose, grind, yield, time, how it tasted.

    Logging a shot: the bean, the roaster's recipe of 20 g in and 44 g out in 29 seconds, and the last shot
  3. Get the verdict and the next grind

    Each shot is scored against the roaster's recipe and your history, with the grind to try next. Watch the score climb as the bag dials in.

More than a shot log

Ask the barista

“Why was that sour?” Answers come from your own shots and the roaster's recipe. It can log a shot or update your shelf for you, and always asks before it saves.

Snap the bag to add it

Take a photo of the label, or paste the roaster's product link, and the bag lands on your shelf with its details filled in.

What home coffee saves

Tell it what you pay at the café and it adds up the difference for every drink you make at home.

Café visits too

Log what you drank out, and where. It adds to the map of which cafés have which beans in the hopper.

What you've saved: totals for the last 7 days, 30 days and all time against the café price
What home coffee saved, week by week.
