Ear Trainer - Chords Practice is an educational Music Theory and Ear Training app designed for iPhone. Developed by Imre Virag, this app aims to improve musicians' listening skills and enhance their musical abilities.

The app offers various features to help users practice and develop their ear training. It includes Interval Comparison, where users can compare different intervals or dyads. Additionally, the app allows users to identify chords, including TriChords/Triads and Seventh TetraChords/Tetrads. For more advanced practice, users can even create their own practices.

There are three different practice modes: Learn, Practice, and Test. In Learn mode, users can practice random intervals or chords in the selected octave, with the result shown on a virtual piano. Practice mode offers similar functionality, allowing users to practice random intervals or chords. Test mode provides random tests in the selected intervals or chords.

Users have the option to set the octaves for the keynote and choose the playing type, such as playing all notes at the same time, increasing, or decreasing. The app also provides statistics based on time and success, allowing users to track their progress.
