## Description

Hit your target proof on the first try. OIML-accurate dilution math, Julian-dated batch history, and zero fluff — built for distillers, not spreadsheets.

Badass Proof Calc is a no-nonsense proof and dilution calculator built for craft distillers, whiskey makers, and serious home distillers.

Plug in your starting proof, target proof, and volume — get the exact amount of water to add. Math is powered by the official OIML alcoholometric tables, so your numbers match what the TTB and the rest of the industry use.

FEATURES
• OIML-accurate dilution calculator
• Density-to-proof conversion using official OIML tables
• Final volume + weight output for both 100-proof and 90-proof references
• Batch history with Julian date numbering for clean record-keeping
• All data stored locally — no account, no cloud, no nonsense
• Works fully offline in the still-house
• Dark, on-brand UI built to live next to a hydrometer, not a laptop

Built by distillers, for distillers. Cut your proof right the first time.
