I Built a Free Home Brewing Recipe & Batch Calculator (Because Brewer's Friend Charges $6.95/Month)
Stop paying $6.95/month for recipe calculations when you can do it right in your browser.
I was tired of brewing calculators that gate basic batch math behind subscriptions. Every time I wanted to scale a recipe or calculate IBUs, I had to log in, enter my details, and hope the site didn't sell my data. For a tool that should take 30 seconds, that's ridiculous.
So I built something better.

- Beer style presets: IPA, Stout, Lager, Wheat, Sour, Porter, Pilsner, and more
