LabBrew: Homebrew Beer Tracker

Brewing is chemistry, and a guessed number ruins a batch. Sticky notebooks, scattered spreadsheets, and half-remembered gravity readings cost you sharp beer — and sometimes a whole fermenter. LabBrew puts every measurement, timer, and calculation for the batch in one place, so the math is done before the wort cools.

One logbook and a full calculator suite for every brew, from grain bill to glass.

• Attenuation and ABV update automatically as you record samples

BREW DAY TIMER

• Guided mash, sparge, boil, and whirlpool stages
• High-resolution hop-addition alerts so bitterness and aroma land on time
• Hold-temperature reminders for every mash step
