Bring your own audio
Import MP3, M4A, WAV, and other iOS-supported audio files. Your listening library stays beside your decks.
Flashcards meet immersion
Learn language from anything you hear.
Listen closely, follow the transcript, save useful language with its original sound, then recall and speak it later. Poly connects the whole loop.
Audio is not an add-on

A complete listening laboratory in your pocket.
Player, transcript, vocabulary tracking, sentence mining, repetition, and speaking practice work on one screen.
Timed transcripts
Create a timed transcript from audio, paste your own text, or import LRC, SRT, VTT, and plain-text files.
Serious playback controls
Slow speech down or speed it up. Set skip length, jump backward or forward, and mark precise A–B loops.
Tap-to-seek sentences
Poly follows timed lines while audio plays. Tap any transcript line to hear that exact moment again.
Vocabulary awareness
See familiar, learning, and new words inside each transcript, with a live familiarity score for the lesson.
Sentence mining with source audio
Save a line as a card with its sentence, timestamp, source lesson, and exact audio clip.
Repeat difficult lines
Practise the active sentence automatically without dragging the playhead back yourself.
Shadowing recorder
Listen, record yourself, and replay your attempt to compare rhythm, stress, timing, and clarity.
Mine useful context.
Save words or complete sentences with meaning, source lesson, timestamp, and exact audio attached.
Train more than recognition.
Practise understanding, producing, listening, dictation, typing, and speaking from the same material.
Remember it later.
FSRS and Smart Review bring language back when recall needs work—not whenever a rigid lesson says so.
Start with something worth hearing twice.
Import one conversation, podcast clip, class recording, or voice note. Poly turns repeated listening into language you can remember and use.
