Strumlane

Tune up, then play. A chromatic guitar tuner and a real-chord game that listens as you strum — scored in chords per minute.

Tune your guitar. Then actually play.

Strumlane is a chromatic guitar tuner and a chord practice game in one app. It listens through your iPhone microphone — no cable, no extra gear.

TUNE Pluck a string and see how close you are in real time. Standard tuning (E A D G B E) with a simple cents meter, so you know whether to tune up or down.

PLAY Chords scroll toward you with diagrams. Strum the right shape in time and Strumlane hears it. Pick the chords you want to practice — from open beginner shapes to sevenths and barre chords.

Learning mode eases the tempo as you go. Challenge mode keeps pushing. Your score is CPM: chords per minute. Twelve correct chords in a minute and a half is 8 CPM. Beat your best.

WHY IT’S DIFFERENT Most guitar apps stop at a tuner, or they teach with on-screen buttons. Strumlane scores the guitar in your hands.

Requires microphone access to hear your instrument. Works best in a reasonably quiet room with an acoustic or an unplugged electric.
