## What is Zym Brewing?

Zym is the brewing app built by a brewer, for brewers. Whether you're crafting your first batch or refining a recipe you've brewed a hundred times, Zym gives you the tools to brew smarter.

GUIDED BREW DAY
Let Zym plan your brew day backwards from your target finish time. Step-by-step guidance through strike water, mash, sparge, boil, and chill — with timers and notifications throughout. Add your own custom steps. Connect your AI Brewmaster for real-time, context-aware advice at every step, though every step works perfectly without it.

LIVE FERMENTATION DATA
Connect an iSpindel, Tilt, RAPT Pill, or Home Assistant and Zym auto-logs gravity and temperature straight onto your fermentation curve. Bring your own device and data link — no accounts, no middleman. Check battery and signal before the sensor even goes in the beer.

RECIPE BUILDER
Build detailed recipes with a full grain bill — all-grain, extract, or partial mash — hop schedule, yeast selection, and water adjustments. Zym calculates OG, FG, ABV, IBU, and SRM as you build. Scale recipes to any batch size in seconds.

BATCH TRACKING
Log every batch against your recipe. Track fermentation with a gravity curve, log temperature readings, and move batches through your pipeline from Planned to On Tap. Attach photos at every stage.

INSTRUMENT SCANNER
Photograph your hydrometer and Zym reads the gravity for you — powered by your AI provider if connected, or enter manually. No more squinting at meniscus lines. Readings log directly to your fermentation curve.

WATER CHEMISTRY
Full water chemistry calculator with BJCP style targets, mineral additions, live Cl:SO₄ ratio, and Campden dosing. Import your water report as a PDF and Zym does the rest.

YEAST BANK & REPITCH
Harvest yeast from a batch into your bank, track each generation, slurry volume, and viability as it ages, then repitch with cell counts and starter size worked out for you.

18 CALCULATORS
ABV, gravity, mash water, sparge volume, carbonation, hop utilisation, yeast pitch rate, refractometer correction, and more — all in one place, drag to reorder.

BJCP STYLE BROWSER
Browse all BJCP 2021 styles with full stats, descriptions, and commercial examples. Compare your recipe against any style target.

BREW DAY TIMER
Schedule hop additions, custom steps, and process notes ,with a live countdown on your lock screen and notifications that fire even when your phone is locked.

BEERXML IMPORT & EXPORT
Bring your existing recipes with you; import BeerXML from any brewing app, and export yours to share or back up. Your recipes are never locked in.

PIPELINE & CALENDAR
See all your batches at a glance in a kanban-style pipeline. Filter by stage, search by date, and track what's fermenting, conditioning, and on tap.

AI BREWMASTER (OPTIONAL)
Bring your own API key from Anthropic, OpenAI, or Google and unlock an AI brewing assistant that knows your recipes, batches, water profile, and equipment. Ask anything, get advice tailored to your brewery. Your data is sent directly to your chosen provider — Zym never stores it. AI features are entirely optional — every feature works without them.

AI MEMORY
Your AI Brewmaster remembers your preferences, past decisions, and brewing style across conversations. The more you brew with Zym, the better it knows you.

DESIGNED FOR iPHONE, iPAD & MAC
One universal app with two-pane layouts and landscape support on the big screen.

LOCAL FIRST
No account required. No login. Your data lives on your device and backs up to your own cloud storage. Zym never sees your data.

## Version history (last 3 releases)

### 1.0.3 — 2026-09-28

A big update — Zym has grown a lot since the last release.

• Live fermentation data: connect an iSpindel, Tilt, RAPT Pill, or Home Assistant and gravity + temperature log straight onto your fermentation curve. Logging starts the moment the sensor goes in the beer, and you can check its battery and signal before it does.

• iPad & Mac: a proper two-pane layout and landscape support — no more blown-up phone screen.

• Yeast bank & repitch: harvest yeast from a batch into your bank, track each generation and its viability as it ages, and repitch with cell counts and starter size worked out for you. Set exact pitch amounts too — packs, grams, or mL of slurry.

• BeerXML import & export: bring your recipes in from any brewing app, and export yours to share or back up.

• Redesigned Home: a dynamic dashboard that surfaces what's next — your active brew day, and what's fermenting, conditioning, and on tap.

• Guided brew day, refined: pause now holds your step reminders and resumes exactly where you left off, custom steps fire at the correct time, and you can jump to the full batch to log pH or notes mid-brew. A live countdown now shows on your lock screen (iOS).

• Reliable pipeline: batches move cleanly between stages, and a brew that's underway shows as "Brewing," not "Planned."

• Polish everywhere: brewhouse efficiency the instant you log your OG, a Pipeline shortcut on the Home screen, two-decimal water additions, tidier number entry, and cleaner AI voice replies.

Built by a brewer who reads every message — questions or ideas always welcome.

### 1.0.2 — 2026-09-14

Guided Brew Day — step-by-step brew day planning, timed backwards from when you want to finish. Timers, notifications, and optional AI guidance at every step.

Instrument Scanner — photograph your hydrometer and your AI provider reads the gravity. Best results with good lighting and a clear meniscus. Manual entry always available as a fallback.

Batch Photos — capture every stage of your brew. Photos save to a named album in your Photos library, organised by batch.

AI Memory — your AI Brewmaster now remembers your preferences and brewing style across conversations.

AI Spending Tracker — see approximate costs per provider directly below your API keys.

Organised Settings — settings now grouped into clear sections for easier navigation.

Strike Temperature Learning — Zym learns your equipment's heat loss and adjusts strike temperature recommendations over time.

Full Backup — export all your data in one tap from Settings → Data.

Plus numerous bug fixes and improvements.
