## What is Brew Science?

Brew Science puts the tools for grinding, brewing and tasting in one app. No account, no ads; the core tools work without a network connection.

◆ Coffee
Brew at home: pick pour-over or espresso, choose your beans and a recipe, then weigh, pour and time it step by step. The grind is converted to your grinder. After the cup, say what's off and get a fix for the next one.
Out for coffee: make a tasting card from a great cup.

◆ Scan a bean bag, log it automatically
Photograph a bag and the roaster, origin, process, variety, altitude and flavor notes fill in. On supported devices, Apple's servers read the photo and don't keep it. Café info cards scan into tasting cards too.

◆ Brew Calculator
Ratio and water planning, a brewing control chart, and extraction yield for cold-brew concentrate.

◆ Espresso Dial-in
Yield and a typical time window from your dose and ratio, with symptom-based fixes for over- and under-extraction. Includes attributed CORE long-extraction protocols; save your own versions.

◆ Grinder Match
Pick two grinders; change either side and the other converts automatically (micron-interval based). 8 popular grinders free; Pro unlocks all 121.

◆ Curated Recipes & Staged Timers
Staged timers that pour with you, with a sound at each new stage and at the finish. Progress shows in the Dynamic Island and on the Lock Screen. Save your own recipes too.

◆ Water Lab
Four target water profiles plus your own recipes, with GH/KH conversion; mineral data for 135 bottled waters.

◆ Grind Size Reference & Photo Measurement
Photo-based D10/D50/D90 measurement against a calibration object, with the full distribution curve.

◆ Bean Cellar & Resting
Record each bag's roast info; resting and peak-flavor windows are estimated automatically. You can also set your own dates. Frozen bags get their own section: days in the freezer don't count, and the window moves out when you thaw them. Finished bags move aside and stay searchable. Widgets show which bag to drink today and how many days it has left, on the Home Screen, the Lock Screen and full screen on iOS 27 (Pro).

◆ Tasting Cards
Pick flavors on the wheel and the card is made: 8 styles, optional cupping scores, a bag's details in one tap. Save to Photos or share.

◆ Brew Rescue
Something off with this cup? Pick a symptom, get a diagnosis path.

◆ Roast Reference
Eight SCA roast levels (Agtron) with their crack stage, flavor and surface oil.

## Version history (last 5 releases)

### 1.0.4 — 2026-10-29

Your shelf now holds frozen beans: room-temperature bags on top, frozen below, and the frozen section can be hidden.
Days in the freezer don't count against the window; when you thaw a bag, its window moves out by those days.
Swipe right to freeze or thaw, swipe left to mark finished; long-press for a menu, or select several bags at once.
Each change can be undone for a few seconds.
"Archived" is now "Finished beans".
Frozen bags get no freshness reminders and stay off the widget.

### 1.0.3 — 2026-10-26

The first tab is now Coffee: Brew at home (pour-over, espresso) and Out for coffee (tasting card).
Brewing at home starts with your beans; the recipe's grind is converted to your grinder.
Adding beans is one page: photograph the bag and the details fill in, or type them yourself.
Bean-bag scanning is more accurate on supported devices.
Timers give a sound and a haptic at each new stage and at the end, each can be turned off, and you're alerted on the Lock Screen when the brew is done.

### 1.0.2 — 2026-10-25

10 new curated recipes, 17 in all: Tetsu Kasuya's New Hybrid and Iced Switch, Hoffmann's AeroPress, four world-champion recipes, George Peng's X Method and more.
Recipes are grouped by brewer, with champion recipes in their own section. Tap an author to see all their recipes.
The X Method has a three-way strength switch based on your last cup.
Home now has two entries, Pour-over and Espresso. The toolbox has new icons.
Offer codes take effect as soon as you redeem them.

New: Lifetime, a one-time purchase that unlocks Pro for good.
Cleaner screens: page notes moved behind the ⓘ button, and the Pro page shows only features and prices.
Shorter, plainer copy.
