BrewPunto, a coffee recipe calculator with a grinder memory

Field notes

The calculator takes a brewing method, quantity, grinder, coffee type, roast, and ratio, then produces dose, water, temperature, timing, grind guidance, and preparation steps. Its example uses a V60 recipe of 18 g coffee to 300 ml water at 93 °C, with a three-minute target. The page also exposes a library and settings area, and states that recipes and preferences remain on the device with installable offline access on compatible platforms.
