SolFun teaches children music theory — properly, not just playfully. Note reading, rhythm, chords and music writing, as progressive exercises and games. SolFun is used in a class, at home or on your own. The teacher or parent creates their space, enrols their students or children and hands them their credentials: each child then finds their progress again on any device. To learn on your own, “I'm learning on my own” opens a few levels with no account; an account and a subscription open everything else. LEARNING TO READ NOTES • Treble and bass clef, a complete progression octave by octave • Three paths: natural notes, accidentals (sharp, flat, natural), stacked notes • Three ways to answer: note circle, piano keyboard or scattered notes • Every new note is introduced in discovery mode first, outside scoring • A second attempt is offered on every question, with no extra penalty • A dedicated help screen engraves the landmarks, shows reading direction, and offers two drills RHYTHM, CHORDS, WRITING • Note values and rests, with a dedicated beat-counting module • Chords: triads and extensions, quality alone or with the root • Music writing: the child draws the note on the staff and the app recognises it • Made-to-measure practice: pick the exact notes to work on GAMES • Mémori — match a note on the staff to its name • Balloons — tap the right note before it floats away • Word Hunt — find a word's hidden letters on the piano keys FOLLOWING PROGRESS • A guided daily session of five to ten minutes • Every finished exercise hands out a collection card to earn and keep • Practice streak, results history, most frequent mistakes • A level is validated with the timer on and fewer than two mistakes: success is earned FOR THE TEACHER OR PARENT Create your space in the app, with Apple or your email address, enrol your students or children, hand them their credentials and follow their progress from your device. You decide how far each child may go, path by path: a beginner does not land on ledger lines in their first week. Export the results whenever you need them. An enrolled child signs in with the class name, their identifier and a four-digit code you give them: they have no account to create. PLANS • Teacher or parent: a yearly or monthly subscription by number of students or children, up to 5, 10, 20 or 50. It lets you enrol up to that number of children and opens every level, for you and for each of them. Enrolled children never pay and never see a price. • Learning on your own: a yearly or monthly subscription opens every level, and your progress follows you on each of your devices. Every plan starts with a one-week free trial, only once per Apple Account and per kind of plan. The subscription renews automatically; cancel at any time in your Apple Account settings, at least 24 hours before it renews. If it stops, nothing is erased, and everything reopens when you subscribe again. BUILT WITH CARE • Notation engraved with the Bravura font, to music-publishing metrics • Every note is played at its true pitch (A4 = 440 Hz) • Do-Re-Mi or A-B-C naming, your choice, at any time • Each child builds their own avatar, and it follows them from device to device • iPhone and iPad, light and dark mode • No advertising, no trackers Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://solfun.web.app/privacy

Verdict

The call

The clearest difference is in-app purchases: One FM at none against SolFun's 10. One FM also leads on device support (4 vs 2) and iOS requirement (15.0 vs 26.0). SolFun's advantage is ads (none vs shown) and update cadence (every 2 days vs every 3 months). On price there is nothing between them.
