iWatchWord

iWatchWord is a vocabulary learning app for iPhone and Apple Watch, designed to keep the words you want to remember close at hand. 【Downloadable Vocabulary Packs】 Browse and download reference vocabulary packs for different languages and learning topics. Downloaded packs can be set as your current study pack and synced to Apple Watch. Downloadable packs will continue to be updated and expanded over time. 【Create Custom Vocabulary Packs with AI】 Tell AI what you want to learn, such as “Travel Japanese,” “Business English,” or “JLPT N1 reference vocabulary,” then preview and save the generated words. AI features use a BYOK (Bring Your Own Key) model. API keys are stored in the device Keychain, and AI requests are sent directly from your device to the third-party AI provider you select. The developer does not receive your API key. 【Learn on Apple Watch】 Sync your current vocabulary pack and favorites to Apple Watch and quickly review words from your wrist. 【Favorites and Management】 Save frequently used words as favorites, manage your personal vocabulary packs, and keep your study state available across iPhone and Apple Watch. 【Pro】 A one-time Pro purchase unlocks more vocabulary packs, more AI packs, additional favorite collections, and more flexible AI generation limits. No subscription required. Some exam-related vocabulary packs are unofficial study reference materials and are not affiliated with or endorsed by the relevant exam organizations.
