EarString
Tuner, chords, AI stems
Free · In‑App Purchases
Load any song and EarString finds its chords, key and tempo on-device. Slow it down, loop tricky bars, tune up, and split stems with AI to isolate any instrument.
EarString is a practice companion for guitarists that does the ear work for you. Load a song and it figures out the chords, key and tempo — right on your device — so you can follow along and learn faster.
CHORDS & TEMPO, AUTOMATICALLY
AI analyzes each track for its chord progression, musical key and beat grid. Follow the changes bar by bar as the song plays.
SLOW DOWN & LOOP
Slow a tricky passage down without changing its pitch, and set an A–B loop to drill it until it's under your fingers.
AI STEM SEPARATION (PRO)
Split a song into vocals, drums, bass, guitar, piano and more — fully on-device. Mute or isolate any instrument to play along, and shape the sound with the built-in equalizer.
CHROMATIC TUNER
A precise built-in tuner listens to your guitar so you're in tune before you play.
LYRICS
View lyrics alongside the song. Fetch them from an online database by title and artist, or type your own.
