Hide vs HideLog

Hide is a leatherworking calculator with cited math. Every SPI, every thread-length rule, every edge-finish recommendation names its source. Pay once at $6.99 for Hide Pro — no subscription, no ads, no scanner. The wedge Most leatherworking apps stop at thread length. Hide includes thread length in the free tier (matches the incumbent's full surface) and unlocks the rest with one $6.99 lifetime purchase: saddle-stitch SPI by leather weight × project, edge-finish recommendation by leather temper, glue selection by use case, dye + sealant by goal, brand-aware presets. Every method tells you whose method it is. Free tier • Thread-length calculator — Stohlman's precision rule and Armitage's generous heuristic, side-by-side, with the leather-thickness math shown • Leather weight oz → mm thickness conversion (1 oz ≈ 0.4 mm per Tandy convention) • 1 saved project slot • Brand picker showing the supplier names Hide Pro ($6.99 lifetime) • Saddle-stitch SPI by leather weight × project type, with awl-hole spacing in mm / inches • Edge-finish matrix — burnish with water + gum tragacanth, burnish + Tokonole wax, edge paint, or wax burnish — selected by leather temper (veg-tan smooth, veg-tan thick, chrome-tan, bridle, oil-tan) • Glue selection matrix — contact cement vs EVA white vs PVA vs hide glue — by use case + dry time + odor • Dye + sealant matrix — spirit / oil / water dye, Resolene / acrylic / wax sealant, with compatibility warnings • Brand-aware presets: Tandy Leather, Buckleguy, Maverick Leather, Wickett & Craig, Horween — typical SKU ranges + edge-finish recommendation per their leather chemistry • Unlimited project log • Citations & Sources screen with every author named Honest authority story Leatherworking has no USDA / AOCS / Knife Steel Nerds equivalent.

Sherman), Corter Leather & Cloth (Eric Heins), plus tannery technical sheets from Wickett & Craig, Horween, and Sedgwick & Co. Every number Hide displays tells you whose method it is so you can verify against the original. The Moon Dog promise • Pay once. No subscription. No ads. • No account. No login. No signup.

Independent verification against your supplier's technical sheets and your own project requirements is your responsibility. © 2026 Roman Kopaliani

Track every hide, every project, and every cost — in one app built for leathercrafters who've outgrown a spreadsheet. Which tannery did that 4 oz veg-tan come from? How much hardware is left? What did this wallet really cost to make? HideLog keeps the answers in one place, for the leather craft hobby — and the side business it can become. 【What You Can Do】 ▷ Leather & Material Inventory Log every hide and supply: tannery, leather type, thickness in oz, finish, color, stock quantity, unit price, and purchase source. Covers leather, thread, hardware, and dye. No entry limit. ▷ Project Log Record every build: item type, cover photo, status, labor hours, and notes. Free up to 5 projects. ▷ Process Log Log each step — cutting, skiving, stitching, edge finishing — with photo, notes, and duration. See how a piece came together, not just the finished result. ▷ Cost Calculation Link the materials you used and HideLog totals your material cost from each unit price. Add labor hours and an hourly rate for a true total cost — no spreadsheet math required. ▷ Suggested Selling Price Turn your total cost into a suggested listing price, with your margin, shipping, and typical marketplace and payment fees built into the math. Know your number before you list a piece. ▷ Auto Stock Deduction Mark a project complete and the linked materials are deducted from your stock automatically. No manual recount. ▷ Pattern Storage Attach pattern files (PDF or image) to any project, so they never get buried in your camera roll. ▷ Tool Tracker Keep condition and maintenance notes for knives, punches, bevelers, pricking irons, and more. No entry limit. ▷ Share Cards & Spec Text Turn a project's specs — leather, thread, hardware, time, cost — into an image card for social media, or a customer card for handmade orders. One tap copies a ready-to-post spec list, so you never retype it. Three themes: Dark, Light, Craft Paper. ▷ Wishlist Keep a running list of leather and tools you want, with estimated price and a purchase link. ▷ Export & Import Export projects and materials as CSV, or everything — including photos and pattern files — as one ZIP to back up or move to a new iPhone. Import a CSV or ZIP exported from HideLog. Free for everyone. ▷ 8 Languages English, Japanese, German, French, Spanish, Korean, Traditional Chinese, and Portuguese. Amounts are shown in the currency you choose. 【Who It's For】 · Leathercrafters whose hide and hardware stash has outgrown a spreadsheet · Makers who want a real cost number before pricing a commission · Sellers at online shops and craft fairs who need actual numbers, not a guess · Anyone who has typed out the same spec list one too many times 【Your Data Stays on Your Device】 Everything is stored locally on your iPhone.
