Regal Vault

Read full description

Most people who love antiques learn in the same scattered way: a paragraph from a reference book, a remark overheard at a sale, a guess at a hallmark that is never confirmed. RegalVault replaces that with structured practice. It covers fifteen fields of the decorative arts and teaches each one through short interactive lessons, then makes you prove what you learned against a question bank that remembers your weak points. Every lesson is written as a dialogue. It presents one idea, stops, and asks you to make a judgement before it goes on. A lesson on porcelain will show you two paste bodies and ask which one rings; a lesson on case furniture will show you a dovetail and ask what it says about the decade. Each one closes with a mini challenge, an observation exercise, an authenticity check and a set of summary notes you keep. What you can study and do: - Fifteen museum cabinets covering furniture, porcelain, silver, paintings, clocks, glass, books, sculpture, coins, militaria, jewellery, ceramics, textiles, lighting and decorative objects. - Object files with production period, country of origin, common materials, identifying characteristics, authenticity indicators, restoration guidance, collector notes and historical background. - A personal collection that fills wooden display cabinets as you work, recording rarity, timeline, country, period, material and preservation difficulty for every piece you catalogue. - Museum stamps and archive pages awarded for completed lessons, plus achievement medals and artifact series to complete. - An Academy with six training modes: a daily lesson, multiple choice quizzes, era identification, material challenges, original-or-reproduction judgements, and a twenty question collector examination. - Automatic repetition of anything you answer incorrectly, so weak distinctions keep returning until they are mastered. - A weekly timed challenge with its own rewards. - A searchable archive of historical periods, furniture styles, ceramic types, wood species, metal finishes, makers marks, hallmarks, artists, manufacturers, restoration techniques, auction vocabulary and museum terminology, with timelines and cross references. - Bookmarks and personal notes on any archive article. - A collector dashboard showing rank, experience, museum level, daily streak, weekly progress, completed lessons, collection completion, examination accuracy, study time and a learning calendar. - Selectable appearance themes and an adjustable typewriter reveal speed for lesson prose. Ranks run from Visitor through Collector, Curator, Restorer and Historian to Master Curator. Each promotion is earned against the question bank rather than handed out for time spent in the application. RegalVault asks nothing of you in return. There is no account to create, no subscription gate in front of the lessons, no advertising and no analytics. The entire corpus of lessons, archive articles and examination questions ships inside the application, so every feature works with no connection at all. Your progress record is written to your device's private storage and stays there. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Read the books you actually want to read. Learn a language through the original text. Reader AI is an AI-powered reader that helps you understand words, sentences, and passages in context. Import your own books, get explanations right where you're reading, chat with AI about what you've read, or switch to listening, all without losing the flow of the original text. 【Vocabulary in Context】 Press and hold a word to see what it means in the current sentence. AI interprets the word based on its context, helping you understand how it is actually used. 【Sentence & Passage Explanations】 Select a sentence or passage and tap "AI Explain" to understand sentence structure, idioms, expressions, and cultural context. Set your native language and proficiency level to receive explanations tailored to your needs. 【Book Chat】 Ask AI about the book you're reading: characters, plot, themes, or a passage you're stuck on. Answers cite the original passages they're based on. 【Audiobooks】 Available for non-mainland China App Store accounts. Turn your books into audiobooks. Preview and choose a narrator voice, follow along with a synchronized transcript, and add translated subtitles. Switch seamlessly between reading and listening at the same sentence, with your listening position synced via iCloud. Audiobooks are currently available for App Store accounts outside mainland China. 【Pronunciation & Learning Notebook】 Listen to the pronunciation of words and phrases, and save expressions you want to remember. Your Learning Notebook keeps the definitions and example sentences from when you saved them. Filter saved items by book or type, and jump back to the original passage at any time. 【Your Books, Your Way】 Import EPUB, TXT, MOBI, PDF, AZW3 and other supported formats. Add highlights and notes, customize your reading layout, and choose between System, Light, and Dark appearances. View your bookshelf as a grid or list, manage books in bulk, and pick up where you left off from Home. Annotate PDFs with handwriting and text, and export them with annotations. For scanned PDFs, word lookup depends on whether the file contains selectable text. 【No Account Required】 Start reading as soon as you open the app. Your books, reading progress, and learning data are primarily stored on your device and in your personal iCloud storage. When you use AI features, the selected text and necessary surrounding context may be processed to provide the requested result. Creating an audiobook processes the chapter text to generate narration. AI-generated content is for reading and learning purposes only and may contain errors. 【Free Reading & Pro】 Importing books, reading, highlighting, note-taking, and PDF annotation are free. Free AI credits are included so you can try contextual word lookup and sentence and passage explanations. Once your free credits are used, a Pro subscription is required to continue using these AI features and to view AI-generated definitions in your Learning Notebook. Pro includes unlimited word lookup, sentence and passage explanations, pronunciation, and Book Chat. Monthly, three-month, and annual auto-renewable subscription options are available. Prices are shown on the purchase screen. Audiobooks and translated subtitles are purchased separately with credits, available as in-app purchases. The cost is shown before you buy. Payment will be charged to your Apple Account upon confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current subscription period. You can manage or cancel your subscription in your Apple Account subscription settings, and restore previous purchases from within the app. Please only import books and other content that you have the right to use.
