LoopListen is an audio player built for one thing: listening again, and again. Open an MP3 from a chat, email or the Files app, choose “Open in Other App → LoopListen”, and it starts looping right away. TAP A, TAP B — THAT'S IT While listening, tap A at the start of a phrase and B at the end. The phrase loops seamlessly. Drag the A/B handles on the waveform or nudge them by 0.1 s to land on exactly the right word. A is placed a fraction earlier so the first word never gets clipped. MADE FOR PRACTICE • Speed from 0.5× to 2.0× without changing pitch • Shadowing pauses between passes — 1 to 10 seconds, or as long as the loop — so you can repeat aloud • Repeat forever, or stop after a set number of passes • Save several loops per file and switch with one tap OPENS ANYTHING, REMEMBERS EVERYTHING • Import from chat apps, Mail and Files via “Open in Other App” • Wide format support: MP3, M4A/AAC, ALAC, WAV, AIFF, CAF, FLAC, Opus, MP2, M4B audiobooks • Video works too: MP4 and MOV show the picture above the waveform, with the same A-B repeat, speed and shadowing pauses — sound stays the focus • Remembers position, loop points and speed for every file • Background playback, Lock Screen and Control Center controls, pauses when headphones are unplugged SIMPLE AND PRIVATE • No sign-up, no ads, no tracking • Your files stay on your iPhone — nothing is uploaded Great for language listening and shadowing, memorising texts, dictation, learning songs, instrument practice, and replaying key moments of lectures or meetings.
