Features
Read full description

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. TERMS OF USE (EULA) Subscriptions are subject to Apple's standard Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
