## What is EarString?

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.

WHY EARSTRING
• On-device analysis — your music never leaves your device for processing
• Works offline (except optional online lyrics lookup)
• Clean, focused interface built for practice
• One purchase, both platforms — your Pro unlock works on iPhone and Mac

EarString Pro unlocks AI stem separation, available as a monthly subscription or a one-time lifetime purchase. Everything else — tuner, chord & tempo detection, slow-down, loops, lyrics — is free.
