Practice Hero

A/B loop, Speed Ladder, hold tracking, session stats, and metronome — everything you need to practice smarter on YouTube.

Practice Hero turns YouTube into a practice room for musicians. Instead of endlessly scrubbing the timeline trying to nail a tricky passage, you get real practice tools bolted right onto any YouTube video. WHAT IT DOES Pitch-preserving speed control — slow a video down to 25% or push it to 400% without the audio turning into chipmunk or demon vocals. Perfect for learning fast licks and solos note for note. A/B looping — set a start and end point and loop the exact section you're working on, as many times as you need. Speed Ladder — the standout feature. Loop a section and let it automatically climb from slow to full speed, step by step, with a hold control for when you hit a wall. The fastest way to get a part from "almost" to "nailed it." Built-in metronome — practice in time with multiple sounds and time signatures. Practice tracking — session stats, notes, and saved loops so you can see your progress and pick up where you left off. FREE AND PREMIUM Core features — speed control, basic looping, pitch shift, auto BPM detection, and a basic metronome — are free. Practice Hero Premium unlocks the Speed Ladder, a saved Loop Library, session snapshots, practice stats and notes, odd time signatures, and more. Practice Hero stores your data locally on your own device. It's built for musicians who are serious about getting better. Already have YouTube open when you install?
