Autochords is a full version music and radio application developed by Astrocode Pty Ltd for iPhone. It is a great tool for songwriters who want to learn how to play chords on guitar, piano, and ukulele, and try new styles of music.

The application offers a variety of progression styles that users can choose from, and once they pick a progression style and a key, Autochords will show them what to play for their Main Progression. Users can preview the entire progression in the selected tempo with the tap of a button. Additionally, the application suggests “Alternative progressions” that users can use for other sections of the song, like a bridge or backing for a solo.

Autochords also provides guitar, piano, and ukulele chord diagrams, so users can easily follow along with the chords. They can also hear how the progressions sound on their chosen instrument. Users can even build and customize their own progressions.

With the one-time PRO in-app purchase, users can unlock even more progressions, export to MIDI, keep track of their favorites, change the tempo, and switch between color themes. Autochords is the ultimate songwriting cheat sheet and inspiration machine for musicians of all levels.
