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.

Ok just got some background I'm a guitarist and not to toot my own horn but I'm pretty good at guitar. But I always felt like my music theory was lacking. I've always wanted to be able to efficiently read sheet music. I feel like this app is the best one out here! Just after a couple minutes I feel like my ability to read music more efficiently has double! I would recommend this is you are a newbie at sheet music. The only issue I have with this app is it only teaches the note names. No timing.

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.
