I tried this out and liked the interface. I even bought this because I was getting better! The dragging to the stave is a frustration however because fingers are big, but did get me familiar with octave notation. As I got further into using the app, I noticed that the ledger lines above and below are not drilled above or below 1-2 spaces. This was a bit of a deal breaker since I am especially weak in reading these notes. Also I did not see an option for syncing across devices.

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.

I'm enjoying this app a lot so far, it's been helpful for keeping my treble and bass reading skills sharp and learning to sight-read tenor clef(bleh!). I do have one big critique, and it's that the random note generation is a little TOO random sometimes. Particularly for lessons, it's silly to me how often I play one that introduces a new sharp or flat and I never have to actually play that new note because of the rng. Lessons should be more focused.
