How it works

Three steps. One sentence at a time.

  1. 01

    Listen

    Hear a clear, natural American English sentence spoken by the model.

  2. 02

    Shadow

    Say it right back. Match the melody, the stress and the pace, not just the words.

  3. 03

    See your pitch, fix the words

    Your pitch contour appears beside the model's, and every word is marked as clear or needs another try.

Shadowing that works

Intonation you can see.

Your voice, drawn against the model

A crisp pitch chart puts your contour inside the native speaker's tolerance band, so rising and falling intonation stops being guesswork.

Shadowtone Session screen: a live pitch chart in hertz comparing your line with the native model while recording.

Word-by-word clarity

Find out which words came through clearly and which need another try, then go again.

Rhythm and stress

Build the rhythm and stress patterns that make speech sound natural, one sentence at a time.

Shadowtone Patterns screen: red words per sentence over time and the patterns you are working on, such as rising end on statements.

Instant, honest feedback

Every attempt is scored on pronunciation, intonation and rhythm, with one clear next step instead of a wall of numbers.

Private by design

Your voice stays on your iPhone.

Scoring runs fully on your device with Apple Speech and on-device pitch analysis. Nothing is sent anywhere.
