Good for practicing reading notes. I've improved significantly because of this app. The exercise to practice writing notes was a nice attempt, but it's too easy to place a note on a line of the stave, like G4, and the app to switch focus to the gap between lines, marking you wrong for that fraction of a millimeter twitch.

Love this app, highly recommended. Memorising all the notes on the staff can be tedious and can require a lot of practice. If you're learning piano, being able to rapidly switch between treble and bass clef can be challenging and takes some getting used to. This app makes all the above A LOT easier. My sight reading has already improved. I have found an issue with the exams. Sometimes when switching between the note-select and note-drag exercises, notes will disappear on the circle of fifths.

This has been so helpful in improving my sight-reading and keeping track of my progress. It has a really useful section on key signatures too. It also tracks your sight-reading response times so you can see your progress, and teaches you to write note as well as read them. It also keeps a record of which notes you know best and how often you hit them correctly (in %). The premium version is a one time purchase of £1.99 and so worth it! Can't recommend enough. Brilliant idea guys, thank you.
