SolFun

SolFun teaches children music theory — properly, not just playfully. Note reading, rhythm, chords and music writing, as progressive exercises and games. SolFun is used within a class: the teacher creates their class, enrols their students and hands them their credentials. Each child then finds their progress again on any device in the class. Without a class, a discovery mode opens the first levels of every module, asking for nothing. LEARNING TO READ NOTES • Treble and bass clef, a complete progression octave by octave • Three paths: natural notes, accidentals (sharp, flat, natural), stacked notes • Four ways to answer: note circle, piano keyboard, scattered notes, or typing the name • 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 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 Create your class, enrol your students, 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 class results whenever you need them. Opening a teacher account goes through an approval step, to protect children's data. A student cannot open an account alone. 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 in-app purchase, no trackers

Verdict
The clearest difference is ads: SolFun at none against Radio M's's shown. SolFun also leads on update cadence (every 2 days vs every 13 months). Radio M's's advantage is device support (5 vs 2) and iOS requirement (15.1 vs 26.0). On price and in-app purchases there is nothing between them.
