Read full descriptionHide full description
Solfe brings the study and the practice of music together: theory, plus the solfège side — ear training, sight-singing and rhythm — all in one place, at your own pace. - Music theory: 14,000+ questions across 8 categories (intervals, key signatures, scales, rhythm, terms, chords, transposition, score analysis), every one with a careful explanation. Notation questions are rendered on a real staff, with a keyboard diagram in the explanation. - Solfège: ear training, sight-singing, and rhythm. Exercises are generated on the fly, so the training never runs out. Sight-singing grades your pitch and timing on the device — your voice never leaves your phone. - Ask about a question: when an explanation doesn't land, ask about that question directly. Answers are grounded in the question, its answer, and the notation. - Today: the home screen picks what to do next - review that is due, or the level you are working through - plus one solfège exercise for when you can use your voice. - Review: spaced repetition (SRS) remembers what you solved and brings it back right before you forget. - Practice exam: 20 questions in 20 minutes, modelled on the structure of Japanese music high school and conservatory entrance exams. Free plan: every question is open - all categories and all levels, up to conservatory entrance level - with 5 sessions a day (a session is 10 questions in theory or ear training; one exercise in sight-singing). Every explanation, score, and keyboard stays visible, and spaced repetition works with a 30-question queue. Solfe Pro (subscription, 7-day free trial): no daily limit, unlimited review, a mastery map broken down by category and by material, the practice exam, and weak-spot drills. Your account is shared with the music learning service Creatone. Active Creatone subscribers get Solfe Pro at no extra cost. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your App Store account settings.
