Understand your glaze recipes with the Seger unity formula, SiO2/Al2O3 ratio, and Stull chart. Core tools work offline on your device. CORE FEATURES (FREE, OFFLINE) - Formula calculation and editable materials database with representative analyses. - Colorant reference with addition levels, oxidation/reduction differences, and precautions. - Firing logs with dates, cone/SK, atmosphere, ratings, photos, and notes. - Your kiln map: filter records, expand nearby points, and send 2–6 selections with a reference to Comparison Lab. - Comparison Lab: compare saved recipes, photos, formula metrics, estimated expansion, conditions, and ratings. Includes a Stull overlay, A4 PDF, and recipe adoption. - Condition checks flag differences and missing records; resume-work cards lead back to unfinished tasks. - Complete backup/restore of recipes, materials, experiments, logs, and photos. Share recipe text or formula/chart images. PRO FEATURES (SUBSCRIPTION) - Reverse solver and separate side-by-side Recipe Compare. - Saved line/triangle blends, experiment ledger, and 3–5 point Next Experiment plans. - Material Substitution: replace one material at equal weight; compare chemistry, Stull position, and estimated expansion. Cost requires matching analysis prices in one currency. Save a separate draft and version 1; leave the source recipe and logs unchanged. - Controlled Retest: select one factor and save CTRL/TEST pieces as a new experiment. - CSV/Japanese OCR import with confirmation before saving; supplier, lot, and analysis history. - Optional iCloud Sync and GPT photo-aware assessment. PRIVACY Your recipes, materials, firing logs and photos are stored on-device by default. A Pro subscriber can explicitly enable iCloud Sync, which also stores this app data in their private Apple CloudKit database. There is no account or sign-in, and no third-party analytics, tracking, or crash-reporting SDK. When you tap to generate a GPT review, a recipe-derived composition summary, up to one firing photo, and a StoreKit-signed transaction used to verify the Pro subscription are sent to the developer's Cloudflare Workers. The transaction is checked with Apple and is not sent to OpenAI; only the composition summary and optional photo are forwarded to OpenAI. The app does no cross-app or cross-site tracking. Expansion and AI insights are relative guides, not guaranteed values. Substitution is an equal-weight calculation, not automatic optimization or historical-lot binding. Condition checks do not establish causes or guarantee reproducibility. Material properties, particle size, clay, and firing affect results; verify with small test batches. SUPPORTED DEVICES iPhone / iPad (iOS 17+ / iPadOS 17+). The interface can be switched between Japanese and English in-app (technical data such as raw-material names remains in Japanese). SUBSCRIPTION Yushiki Pro is available as a monthly subscription at 400 yen or a yearly subscription at 3,000 yen, each with a 7-day free trial. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings after purchase.
