Plectro is the first guitar tracker that actually listens. Most practice apps make you tap "start," set timers, and log everything by hand. Plectro doesn't. Put your phone down, pick up your guitar, and play — Plectro listens, automatically logs your session, and shows your pitch in real time. WHY PLECTRO - Just play. Automatic session tracking, no timers or buttons to fuss with. - A real-time tuner accurate to the cent — see instantly whether you're sharp or flat, and which way to tune. - Live note detection as you play. - Streaks that reward showing up every day. - A clean, distraction-free dark design made for late-night practice. PRIVATE BY DESIGN Everything happens on your iPhone. Your audio is analyzed entirely on-device — never recorded, never uploaded. Plectro keeps only the numbers: minutes practiced, notes detected, and your stats. BUILT FOR REAL PLAYERS Whether you're picking the guitar back up after years away or building a daily habit, Plectro turns practice into progress you can actually see. Tune. Play. Track. Improve.
