Practice Lab Looper

Turn YouTube (videos + Shorts) and Instagram Reels into a practice tool: speed, pitch, and a draggable A/B loop.

Practice Lab Looper turns YouTube, YouTube Shorts, and Instagram into a real practice tool. Set a loop on any tricky passage and play it back on repeat. Slow the video down without changing the pitch, or shift the pitch to match your tuning. Save your loops to a library and jump back into any of them with one click. The video reopens right where you left it, so your practice spots are always ready. The built-in speed trainer takes any loop and builds it up for you. Set a starting speed and the number of reps you want at each level, and it raises the tempo automatically as you go. You put in the reps, it handles the progression. YouTube and YouTube Shorts are fully supported. Instagram support is included and improving, working in most cases with ongoing fixes as Instagram changes its layout.Built by a guitar teacher for musicians who learn from video.
