EarString helps guitarists learn songs: a chromatic tuner, AI chord and beat detection, slow-down without pitch change, A–B loops, and on-device AI stem separation to isolate or mute individual instruments.

Common questions
Stem separation is slow or heats up my device. Separation runs a neural model fully on-device; it's compute-heavy. Keep the app in the foreground until it finishes — leaving the app cancels it.
Online lyrics don't appear. Lyrics are fetched from a public database by title and artist; some songs simply aren't in it. Make sure the online lyrics option is enabled in settings and you're online.
EarString Pro
Stem separation is a Pro feature, available as a monthly subscription or a one-time lifetime unlock. Manage or cancel subscriptions anytime in your Apple ID account settings.
