Homebrew Calculator: Brew Day

Fix off-target gravity, build unlimited homebrew recipes, run multiple brew timers and track every batch from prep to package — entirely offline. BUILD UNLIMITED RECIPES Create as many beer recipes as you like. Record batch targets, fermentables, hops, yeast, other ingredients, notes and an ordered brew-day plan. Duplicate a recipe when you want to iterate without losing the original. TRACK THE COMPLETE BREW DAY Start a batch directly from a recipe and work through every step from preparation, mash and boil to chilling, fermentation and packaging. Each batch keeps its own recipe snapshot, completed steps, timestamps, measurements, timers, calculations and notes. FIX GRAVITY BEFORE IT COSTS THE BATCH Turn an off-target reading into a clear action. Calculate dilution and gravity adjustments, hydrometer temperature correction, fermented refractometer correction, Brix/SG conversion, strike-water temperature and estimated ABV. TIMERS THAT STAY WITH YOU Run multiple named timers, schedule hop additions by boil time remaining, receive local notifications and follow the next action with Live Activities on the Lock Screen. KEEP A USEFUL BREW LOG Review previous batches, measurements and completed steps in your journal. Brew a batch again from an existing plan, or export a complete summary and CSV. YOUR FIRST TRACKED BREW IS FREE Recipes are always unlimited. Try one complete tracked brew session without starting a subscription. Brew Day Pro Lifetime is a one-time purchase; Brew Day Pro Monthly unlocks the same unlimited tracked sessions while active. LOCAL BY DESIGN No app account, advertising or analytics SDK. Your recipes and brew records stay on your device unless you choose to export or share them. SUBSCRIPTION INFORMATION Monthly automatically renews each month until canceled in your Apple Account subscription settings. The purchase screen shows your localized price before confirmation. The free brew is an app allowance, not a subscription trial, and never automatically becomes paid. Lifetime is a separate one-time purchase; buying Lifetime does not cancel an existing Monthly subscription. Calculations are estimates and do not establish that fermentation is complete or that a batch is safe to consume. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
