Cordwise is the offline companion for anyone who heats with wood. Whether you buy firewood, sell it, or cut your own, Cordwise helps you get a fair deal, burn the best wood, and stay ahead of winter - all without an account, ads, or an internet connection. DID YOU GET A FULL CORD - OR GET SHORTED? The most common firewood scam is selling a "cord" that's really a face cord (as little as a third of a full cord) or a loosely thrown pile. Stack your delivery, punch in the length, height, and depth, and Cordwise instantly tells you how many real cords you received, names the size, and flags whether the measure is fair or short. Enter the price and it shows your true cost per cord - the only honest way to compare sellers. KNOW YOUR WOOD Browse 41 common North American firewood species ranked by heat output, with the figures that matter: million BTU per cord, green and seasoned weight, coaling quality, smoke, sparks, splitting ease, and seasoning time. Compare any two woods side by side, and see what a cord of each is worth in gallons of heating oil, propane, therms of natural gas, kilowatt-hours, or bags of pellets. SEASON IT RIGHT Burning wet wood wastes heat and builds dangerous creosote. Estimate how long your wood needs to dry from its species, split size, and how it's stacked, and get a "ready by" month. Reading a moisture meter? Cordwise interprets the number and tells you if it's ready to burn. PLAN YOUR HEAT Size a wood stove to your space, climate, and insulation, estimate how many cords you'll burn in a season, and compare the cost of heating with wood against oil, gas, propane, electricity, and pellets to find your cheapest source of heat. LEARN THE CRAFT Clear, illustrated guides cover what counts as a cord, how to measure a delivery, seasoning, splitting and stacking, choosing the right wood, creosote and chimney safety, stove sizing, and buying smart - plus a plain-English glossary. KEEP A LOG Save each delivery with the seller, species, price, and measurement to build a running record of what you've bought and whether you got your money's worth. PRIVATE BY DESIGN Cordwise works entirely on your device. No account, no sign-up, no network connection, no tracking, and no in-app purchases - buy it once and own it. Heat and weight figures are typical seasoned values compiled from public references including the USDA Forest Service and university-extension publications, and vary with region and moisture. Cordwise provides general information and planning estimates only; always follow your stove and chimney manufacturer's instructions, have your chimney inspected and swept regularly, and comply with local codes. ## Version history (last 5 releases) ### 2.1 — 2026-08-08 Version 2.1 adds Winter Runway command center with deterministic demand scenarios, reserve policies, seasonal readiness windows, purchase-gap and first-30-day risk analysis, monthly runway charts, delivery economics, maintenance gating, recommendations, and an offline share brief This release also refreshes the native iPhone and iPad experience, accessibility, privacy boundaries, and App Store screenshots.
