FretBored

You know what notes sound like. You just can't find them fast enough. FretBored fixes that.
It plays a sequence of notes, you play them back on your real guitar, and the app listens through your mic to score your accuracy and timing. It's ear training that actually feels like a game with combos, XP, daily streaks, and a structured curriculum that takes you from open strings to full-neck fluency across all 12 frets.
No guitar handy? Half the modes work without one.
