This is a note and song teaching app I made to help kids learn music. It has cute graphics and fun play modes, while remaining true to actual musical education by using real musical notation. This is a free version that lets you try the first few lessons and songs, with the rest available for in-app purchase. Video at:https://www.youtube.com/watch?v=sfeYYW0Mqw8&feature=youtu.be Feedback from a music teacher: "It teaches the visual association of staff notes-to-keyboard keys in a way that is sympathetic to children's motivation and need for reward. The built in teacher and fade-in answer are great for this kind of bland memory-work, as kids absorb and memorize the notes, they rely less and less on the help. With this app I can get kids whose parents don't read music or play a musical instrument to learn this vital reading skill in a much shorter time scale. It also encourages parents or other siblings to learn to read." Also check out the review at theiphonemom.com! From learning the basic single notes to scales, a flashcard and music game format teaches your child note names and positions using a piano keyboard. Cute characters appear to guide and support learning. 36 lessons and songs teach note basics, clefs, scales, arpeggios, sharps, and flats. -Treble and Bass clef -Note names pop up as hints if too much time passes -CDE or Do Re Mi (solfege) can be chosen. -Lessons and songs are graded to track progress -Free play piano mode for fun!

Verdict
The clearest difference is rating: Duolingo at 4.7 against Note Teacher Lite's 3.6. Duolingo also leads on update cadence (weekly vs every 45 months) and ratings volume (5.5M vs 7). Note Teacher Lite's advantage is ads (none vs shown) and iOS requirement (11.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Note Teacher Lite sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Duolingo holds the better App Store score, 4.7 against 3.6.
