BrewingCalc is a professional toolkit for homebrewers — clean, fast, and built for serious brewing. Whether you're calculating bitterness, estimating ABV, or converting between metric and US units, BrewingCalc gives you all the tools you need in one place. CALCULATORS INCLUDED • IBU (Glenn Tinseth) — Calculate International Bitterness Units for up to 10 hop additions. Add or remove additions as your recipe requires, then enter hop weight, alpha acid %, boil time, batch volume, and wort gravity. Get per-hop and total IBU. Supports metric and US units. • ABV Table — Determine alcohol by volume using a precision 60-point specific gravity interpolation table. Supports both Plato and SG inputs. • ABV Formula — Temperature-corrected ABV calculation using a polynomial formula. Accounts for the measurement temperature of both original and final gravity readings. • Calories — Estimate total and per-100 ml calories from original gravity, final gravity, and batch volume. Uses the Real Extract (RE) method. • Brix / Refractometer — Convert refractometer readings to gravity and ABV. Two modes: enter original and final Brix, or work backwards from current gravity and corrected Brix. Includes wort correction factor support. • Unit Converters — Four precision converters: – Volume: litres, millilitres, decalitres, US/UK gallons, fl oz, pints – Weight: kilograms, grams, pounds, ounces – Temperature: Celsius, Fahrenheit, Kelvin – Gravity: Plato ↔ Specific Gravity DESIGNED FOR BREWERS All formulas follow established brewing science — Glenn Tinseth's IBU model, the Real Extract calorie method, and standard Brix correction. Your inputs are saved automatically, so you can pick up right where you left off. No ads, no subscriptions, no account required. Works great on both iPhone and iPad.

Verdict
The clearest difference is update cadence: BrewingCalc at every 2 months against Smart's every 6 months. Smart's advantage is iOS requirement (15.6 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
