Extraction Lab
Coffee Intelligence & Tracking
Free · Designed for iPad. Not verified for macOS.
Extraction Lab is a professional-grade coffee companion designed for enthusiasts who care about every variable — from bean origin to extraction yield.
**AI-Powered Coffee Intelligence**
Instantly digitize your coffee bags using multi-tier AI extraction:
• Cloud Vision: Anthropic Claude or OpenAI GPT parse labels in seconds with near-perfect accuracy.
• Local AI (Gemma): On-device intelligence using the Gemma model and MLX framework — no data ever leaves your phone.
• Rule-Based Fallback: Robust pattern matching for offline use.
• Hallucination Guard: Automated cross-verification between AI output and raw OCR ensures data integrity.
**Precision Brewing Tools**
• Guided Brewing: A 3-phase coordinator — Setup, Live Timer, Detailed Log — walks you through every extraction step by step.
• Cold Brew Tracking: Start a cold brew and let it run. Background aging timer with push notifications tells you exactly when your brew is ready.
• Draft Recovery: In-progress brews auto-save. Close the app, come back later, pick up where you left off.
• Recipe Templates: Build custom brewing recipes with step sequences and automatic weight proportions.
• Ratio Calculator: Instant dose-to-water calculations for any brew method.
**Ecosystem Integration**
• Live Activities: Monitor active brews on your Dynamic Island and Lock Screen without opening the app.
• Apple Watch: Timer mirroring lets you track brews hands-free from your wrist.
**Organized Lab Management**
• Workspaces: Create separate environments for Home, Office, or Roastery. Full data isolation between labs.
• Bag Tracker: Visual remaining-weight tracking with manual weight adjustments and low-stock alerts.
• Freshness Monitoring: Automated roast-age tracking with optimal brew-window indicators and peak-freshness notifications.
• Coffee Library: Rich bean catalog with origin data, roast level, and full extraction history per bag.
**Analytics & Insights**
• Sensory Profiling: Map every brew on a 5-axis taste profile — Acidity, Sweetness, Body, Finish, Balance.
• Extraction Metrics: TDS tracking with auto-calculated Extraction Yield and built-in quality assessment.
• Origin Heatmap: Visualize your global coffee journey across an interactive world map.
• Brew Trends: Charts for rating trends, method frequency, and extraction consistency over time.
**Privacy & Sync**
• All data syncs seamlessly across your devices via iCloud.
• Local AI mode keeps everything on-device. Your data never touches a third-party server unless you choose Cloud Vision.
• Full JSON export and backup for your entire library.
Extraction Lab is built for the coffee professional, the home enthusiast, and anyone who wants to turn great coffee into a repeatable craft.
