Photograph the bag and get the water temperature and grind for that bean. Tell it how the cup tasted and the next one corrects itself.
The same bag of beans, a different cup every time.
Usually it comes down to two things: water temperature and grind size.
Brew by Bean treats the whole loop as one thing — from photographing
the bag to the one word you give it after drinking.
■ Scan the bag
The camera reads the roast date, roast level and processing method.
It all happens on your device; the photo is never uploaded anywhere.
If a bag won't read, type it in — it makes no difference to the result.
■ Tuned to the bean
Roast level, processing method and days since roast decide the water
temperature and the grind.
Light roasts are dense and resist extraction, so the water goes hotter
and the grind finer. Dark roasts give up solubles easily, so the water
goes cooler and the grind coarser. Fresh off the roast, the bloom runs
longer to let the CO2 escape.
It isn't an app that just hands you numbers.
Pro shows you why each one is what it is, brew by brew.
■ Brew
Nine built-in recipes, for conical drippers, flat beds and immersion
switches. Pours are shown in grams, and the things that ruin a cup if
you forget them — opening the valve, dropping the temperature — are
announced with sound and haptics slightly before they're due.
A Live Activity keeps the next target on your lock screen.
■ Tell it how it tasted
Three questions: sour or bitter, sweetness, body.
Sour means under-extraction, so the grind goes finer and the water
hotter. Bitter goes the other way. Next time you brew that bean, the
corrected recipe is what you get.
Answer "just right" a few times and the parameters converge and stop
moving.
■ Follow the origins
Every bean you brew stays on the map: which countries, which growing
regions, how many bags. Bags whose origin couldn't be read are kept
as "unknown" rather than quietly dropped, so the count always adds up.
■ What the free version does
One bean and one recipe, "Basic".
The whole loop runs — scanning the bag, the reasoning, the timer, and
the correction landing in your next cup. It isn't a trial, so it
doesn't expire.
