AB Looper vs LoopPlay

AB Looper is a video player that lets you set A and B loop markers to repeat specific sections of any video. Paste a YouTube, Instagram, or direct video URL, set your loop points, adjust playback speed, and practice any section on repeat. Star your favorite videos for quick access and browse your full history to pick up right where you left off. Built for musicians, dancers, language learners, and anyone who needs to drill a specific moment in a video.

Practice at your own pace, in your key, on iPhone and iPad. LoopPlay helps you work through a difficult passage, learn a song by ear, or practice a phrase in another language. Open your own audio files, repeat the part you need, and use Pro to adjust speed and pitch independently. [A-B Loop & Saved Points] Set a start point (A) and end point (B) to repeat a section. Your loop points are saved per file and restored when you open it again. [Speed Control] Slow down a passage without changing its pitch, or speed it up as you improve.
