I love this app. It's easy to use, and makes learning to read so easy and fun. The Stave Writing exercises could use some work. I don't like how it uses A4 and C6 terminology to tell you what note to input. I often get it wrong by just an octave. I wish it could also play the note it wanted you to write, because often when I'm writing in real life, I'm just trying to get down the sounds that are in my head, I don't care about the note names. Still, I love this app. I definitely recommend it.

Nice app. It's helping me for sure. My only complaint is having to drag a note to the staff. It's supposed to help you write a note quickly but on my phone, it doesn't akways drop where I want it and it marks it wring, even though I know where the note is supposed to go. It's frustrating that you can't turn this off. I want more exercises that simply show the note and you hit which note it is. That's the only reason I give it 4 stars and not 5. Great app overall.

Awesome except dragging for note writing sucks. I like the exercises and the progression of lessons a lot. The interface is lovely except for the note writing exercises. These require dragging a note to a line. Why not just click on an enlarged note paper? Or multiple choice of drawn notes that are in random order? Especially doing sharps and flats makes is frustrating.
