A PLAN THAT FITS YOU • Describe your goal in your own words. • Choose your level: beginner, intermediate, or advanced. • Pick a length from 7 to 90 days, or let the AI decide. • Set how much time you have each day. • Edit, reorder, add, or regenerate any day. A LESSON FOR EVERY DAY • Open any day for a full lesson: overview, explanation, examples, common mistakes, best practices, and practice exercises. • Get suggested articles, courses, videos, and docs for the day's topic. • Save your own links and write notes next to each lesson. STAY ON TRACK • Today shows what to study now across all your plans, and what to catch up on. • Daily reminders at the time you choose. • Mark days complete and watch your progress and streak grow. PRIVATE BY DEFAULT Study Mood uses Apple Intelligence, so plans and lessons are generated on your device. Your plans, notes, and resources are stored on your device. No account, no sign-up, no ads. Prefer OpenAI models? Add your own OpenAI API key in Settings. The key is kept in your device's Keychain, and only the study topic and the day's title and description are sent to OpenAI under your own account - never your notes. ON IPHONE, IPAD AND MAC A native SwiftUI app with a three-column layout on iPad and Mac. FREE AND PRO Try it free: create plans and generate your first lessons and resource searches at no cost. Study Mood Pro unlocks unlimited lessons and resource suggestions, available as a monthly or yearly subscription. Payment is charged to your Apple Account; subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel in your App Store account settings. AI-generated content can contain mistakes. Double-check important facts with trusted sources. Apple Intelligence requires a compatible device with Apple Intelligence turned on. Without it, you can use your own OpenAI API key.
