From the developer:
Learn The Notes! is a smart and friendly Mac application to improve music sight reading skills. You get drilled on notes from the treble and bass clefs. Optionally, you can include extended octaves (ledger lines) and accidentals (sharps and flats). The training algorithm is flexible, meaning that you tell the app when to consider a note "learned". You can check your progress and response time for each note.
You may want to check out more Mac applications, such as Learn Music Notes, Note Trainer - Learn To Play Music or Learn English - Complete Audio Course Beginner to Advanced, which might be similar to Learn The Notes.
