OLLA Brew Lab vs CoffeeStory

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. In Roast to Cup, the roastery workbench for curves, roast profiles and inventory, the design workbench opens free; adding and delivering are 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 Free: dial targets for first crack, drop and development ratio, and read the projected first-crack window, drop temperature and development ratio, with no machine connection. With OLLA Pro, save a design to the curve library, start a roast from it, 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 1,700+ 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. OLLA Pro adds multi-sample blind 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 marked Planned. 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.
