About

SkilletLog

Features
Read full description

The first iOS app built for cast iron skillet collectors. Log every piece with the exact fields collectors actually care about — in one place. No more spreadsheets with no column for a heat ring notch. No more "did I already buy this size?" moments at a flea market table. SkilletLog is a purpose-built iOS tracker for the cast iron hobby. 【What You Can Do】 ▷ Cast Iron Ledger Log brand (Griswold, Wagner, Lodge, Birmingham Stove & Range, Vollrath, Favorite, Wapak, or unmarked), size number, pattern letter and number, molder's mark, gate mark, logo style, heat ring with notch count and positions, rust condition, carbon buildup, seasoning state, status, source, purchase price and date, and estimated value. Free up to 20 pieces. ▷ Restoration Log Record every electrolysis session (solution, duration, voltage), seasoning round (oil, count, temperature, duration), and cleaning pass (material used) — with before-and-after photos and a full timeline per piece. Always free, no limit. ▷ "What Is This?" Share Card Turn what you've actually observed — gate mark, pattern number, logo style, heat ring — into a clean card built for asking a real collector community for a second opinion. SkilletLog never guesses the brand or era for you. It just organizes your observations so the answer comes from people who actually know. ▷ New Addition & Restoration Share Cards Celebrate a new piece joining your collection, or a finished restoration with before/after photos and the process behind it — electrolysis time, seasoning rounds, and more. Free with a watermark; Pro removes it. ▷ Collection Overview Share Card Hand-pick up to 9 pieces and share a grid image of your collection. ▷ Wishlist Track brand, size, budget, priority, and notes for pieces you're hunting. No limit — even on the free tier. ▷ Duplicate Check Search your collection and wishlist at the same time, by brand or size, before you buy. Built for the moment you're standing at a flea market table trying to remember what you already own. ▷ Stats See a brand breakdown chart, total piece count, and total collection value — in your choice of 8 currencies. ▷ CSV & PDF Export Export your full collection, provenance notes, and restoration logs. Always free, Pro or not. 【Who It's For】 · Collectors whose spreadsheet has no column for "heat ring notches" · Pickers who need a duplicate check before buying at a flea market or estate sale · Restorers who want documented before/after proof of every electrolysis and seasoning session · Anyone who's posted a blurry "what is this?" photo and wished they'd shown the right details 【Your Data Stays on Your Device】 Everything is stored locally on your iPhone. Nothing is uploaded to external servers. No account required. No risk of losing your collection data if a service shuts down. 【Pricing】 · Free: Up to 20 pieces. Restoration logs, wishlist, duplicate check, stats, CSV/PDF export, and share cards (with watermark) are all included at no cost. · SkilletLog Pro (one-time purchase): Unlimited pieces, watermark-free share cards, and your handle shown on cards. Pay once, yours forever. ---------------------- Developer: Kore Apps Contact: support@kore-apps.com ----------------------
