Phrabbit: Shadowing & A/B Loop

The surest way to make a sentence truly your own — listen, repeat, and say it out loud. Phrabbit is an A/B loop practice app for language learners. Grab any passage from an audio file, a video file, a podcast, or a YouTube stream, loop it until it clicks, and now speak along to compare your own pronunciation. ◆ Shadowing · Listen to an A/B range, then repeat it in your own voice · Play your take over the original and compare the waveforms (audio files) · The passage's subtitles appear on the shadowing screen, highlighting each line as it plays (audio files) · Shadowing gap — automatically leaves time to speak between loops, with a countdown · Shadowing also works with video files and YouTube streams · My Recordings — save your best takes and pick practice back up on the same range ◆ A/B looping right on the waveform · Set precise ranges with your fingertip while watching the waveform · Loop as much as you want, adjust speed (0.5x–2.0x) · Save important ranges as bookmarks ◆ Practice with video · Bring in video files already on your device (MP4, M4V, MOV) and loop them the same way · Attach an SRT or VTT subtitle file, show it over the video, and nudge the sync if it drifts · No subtitles? Mark an A/B range and convert just that part with speech recognition · Fullscreen practice — turn sideways for subtitles and range controls together · Tap a word in the subtitles to save it to your wordbook with its context · Videos are referenced, not copied, so they use almost no app storage ◆ Comfortable anywhere, anytime · Background playback — loops keep running with the screen off or while you use other apps · Sleep timer — auto-pause after 5, 15, 30, or 60 minutes · Earphone remote — the previous/next buttons step through sentences (or 5 seconds, on a file with no transcript) · Bookmark queue — tap Play All to practice saved ranges back-to-back, and skip between them from the Lock Screen · Control playback right from the Lock Screen and Control Center ◆ Speech to text (STT) · Turn speech into sentence-by-sentence text, synced to the waveform in real time · See exactly which sentence is playing as you learn · Type subtitles yourself — practice from your own script when speech recognition struggles with the audio, and your typed lines stay put even if you run recognition later · Apple Intelligence subtitle translation — translate a whole transcript on your device and read it beside the original (requires iOS 26.4 and an Apple Intelligence capable device) · On-device processing — your audio is never sent to an external server ◆ Many sources · Import audio files (mp3, m4a, and more) · Import video files (MP4, M4V, MOV) · Podcasts — browse shows curated for the language you are learning, or add one by name or RSS address · Download podcast episodes, and bring in your Apple Podcasts subscriptions · Practice any YouTube link as a stream ◆ Keep your library in order · Folders — group your material, and nest folders inside folders as deep as you like · Favorites — mark what you open most and reach it straight from Home · Search — finds what is tucked inside a folder, and shows you where it lives ◆ Tools that help you learn · Wordbook — save words you don't know and review them · AI word explanations (Beta) — tap a word in your wordbook and Apple Intelligence explains it on-device, in context · Stats — see your practice time and streak at a glance · Works on both iPhone and iPad Start free.
