OLLA Brew Lab is a coffee workbench for iPhone and iPad that keeps roast curves, brew logs and cupping records in one place. It is made for home roasters, specialty coffee enthusiasts and small roasters. Bean cards, brew logs and cuppings are free. Roast to Cup, the roastery workbench for curves, roast profiles and inventory, is part of OLLA Pro. ROAST CURVES (OLLA PRO) Log a roast live with large buttons for charge, yellowing, first crack and drop; development ratio and weight loss follow from what you record. Replay any curve, compare batches, and set a batch as your baseline. Import curve files in 11 formats; the source is detected from the file itself. ROAST PROFILES: DESIGN BEFORE YOU CHARGE (OLLA PRO) Set targets for first crack, drop and development ratio, and see the first-crack window, drop window and weight loss projected on the spot. No machine connection is needed. Save a design to the curve library, or export it as .alog, JSON or CSV. YOUR BEAN LIBRARY One card per bag: origin, variety, process, estate, altitude, roast level, roast date, purchase details and your own notes. Resting and drinking windows count down on their own; a Home Screen widget shows a pinned bean. Photograph a label, a bean list or a cafe menu and OLLA reads it on device, showing the words each field came from; nothing is saved until you confirm. On supported devices, Apple Intelligence fills gaps, corrects misreadings and adds explanations and translation in three languages, all on device. The Coffee Codex holds 2,000+ cross-linked entries, from origins and varieties to processing and brewing. BREW LOG Record dose, grind, water temperature, ratio, TDS, extraction yield, timing and sensory impressions. The Tools tab sits alongside, with a step-recipe brew timer, an extraction-yield calculator and brewing-water recipes. CUPPING Score on a classic ten-attribute sheet, or use sensory scoring: cup profile, quality impression and five-cup consistency. Describe flavor with 16 everyday words or the full flavor wheel, and export a cupping sheet as a PDF. For professional sessions, OLLA Pro adds blind-coded assessment with cup-by-cup records and a five-class verdict from L5 to L1. FIELD GUIDE City coffee guides, one volume per city, readable offline. Tokyo, Osaka, Kyoto and Fukuoka are published; the other cities on the city bar are still being curated. Each list is selected from public data by OLLA's own scoring. COFFEE JOURNAL Beans, brews, cuppings and roasts stay linked, gathered in one archive with search, filters and yearly stats. HOW PEOPLE USE OLLA · A home roaster designs the next batch, logs it, and cups it a few days later on the same bean card. · A specialty coffee drinker scans a new bag, watches its resting window and dials in a pour over. · A small roaster keeps green and roasted stock, lot codes and labels in one ledger with OLLA Pro. PRIVATE BY DESIGN No sign-up is required. No tracking, no ads, no third-party analytics. Your records stay on your device, and in your own iCloud if you turn on sync. Camera access is requested only when you scan and photo access only when you pick a photo; recognition runs on device. OLLA works in English, Simplified Chinese and Japanese. OLLA PRO OLLA Pro includes Roast to Cup (roast curves, pre-roast design, inventory, labels and assessment sessions), iCloud sync across devices, PDF reports with your shop name, and advanced widgets.
