SolFi Ear Trainer 3 is an iPhone application developed by CutDek Productions LTD, designed for music students aiming to enhance their listening skills. This app offers fundamental exercises commonly utilized in music education, assuming users possess a basic understanding of music theory.

The application features three main exercises. Pitch Dictation challenges users to identify notes played sequentially in relation to a given tonic note. Chord Identification requires users to recognize chords from a set of options based on notes played in a specific key. Interval Identification prompts users to identify intervals between two notes played either melodically or harmonically. Additionally, users can access a piano keyboard in landscape mode, with the current exercise's tonic note highlighted in red for guidance.
