The Woodworker's Companion

Woodworking calculators, 600+ species lookup, quotes, inventory & shop journal. 100% free, no ads. Data stays on your device.

Woodworker's Companion is your all-in-one shop assistant: calculators built for woodworkers, a full business suite, and utilities that stay out of your way—100% free. No subscriptions. No blocking or irrelevant ads. Your data never leaves your device unless you choose to move it.

PRIVACY FIRST Everything is stored strictly on your phone. Clients, projects, inventory, quotes, and journal entries stay locally on your device. Nothing is uploaded to the cloud unless you explicitly export a backup or turn on cloud backup to your own account. There are zero in-app overlay, or video ads. Any hard-coded affiliate links are only for products I genuinely recommend, and your data is never used to target you. I'm committed to keeping it that way.

CALCULATORS BUILT FOR THE SHOP All calculators support both metric and imperial measurements. • Board Foot: Calculate lumber volume, cost, and waste. Save board lists with custom statuses (shopping list, ordered, received). • Fraction Calculator: Add, subtract, multiply, and divide in fractions. Includes a kerf mode for cut counts with precision that matches your tape measure. • Project Pricing: Multiple pricing models so you can quote accurately and profitably. • Cut List Optimizer: Minimize waste with 2D sheet-goods layouts and visual cutting diagrams, plus a dimensional-lumber cut list for boards and sticks. • Wood Movement: Calculate seasonal expansion and contraction for 20+ species. • Finish Mixing: Determine shellac and custom finish ratios with clear mixing instructions. • Epoxy Resin: Exact resin and hardener amounts for any size pour. • Spacing Calculator: Evenly space holes, slats, and spindles along a run.

FULL BUSINESS SUITE • Project Management: Track tasks, time entries, and expenses. Use custom statuses (Quote, Design, Construct) and document change orders to track scope and price changes. • Inventory: Manage lumber, tools, consumables, and hardware. Create custom fields, log storage locations, and get low-stock alerts. • Quotes & Invoices: Create quotes, convert them to invoices, and track payments. Customize your business profile with your name, address, and logo. Print, export as PDF, or share via email and Messages. • Clients: Keep contacts, notes, and project history organized in one place.

WORKSHOP JOURNAL • Log notes, photos (with annotations), voice memos, and milestones. • Record measurements with specific labels and units. • Organize your thoughts by project or date using the active-build dashboard.

UTILITIES & CUSTOMIZATION • Wood Lookup: Browse 600+ wood species offline with photos, Janka hardness, filters, sort, and favorites. Search by common or scientific name—no account and no download required. • Decibel Meter: Measure shop noise, save readings, and use A-weighting for consistent results. • Unit Conversions: Swap instantly between length, area, volume, weight, temp, and speed. • App Settings: Customize your theme (light/dark), currency, language, project statuses, and inventory fields.

DATA & BACKUPS You own your files. Enable automatic cloud backups to securely sync your shop data across devices using your personal iCloud or Google Drive account. Because there is no centralized backend server, your data stays strictly between your phone and your private cloud—I never have access to it. Prefer to do things manually? You can still manually export a full backup (JSON or a ZIP including your photos and voice memos) directly from Settings to store on-device or move to a new phone.

BUILT BY A WOODWORKER, NO LOCK-IN I'm a one-person team and a professional builder. I built this app to solve real problems in my own shop, and I am focused on making it the most useful, fast, and respectful tool for other woodworkers. There is an optional Support/Donate section if you want to buy me a beer, but you will never be forced to pay a fee or subscription. Honest feedback is always welcome!
