## What is ShadowFlow?

ShadowFlow turns YouTube videos into living language lessons.

■ Watch with karaoke subtitles
Subtitles highlight word by word in sync with the video, so you never lose your place. Tap any line to jump to that scene.

■ Tap any word you don't know
The dictionary opens instantly. Save words with one tap — review them as flashcards, hear the pronunciation, and jump back to the exact scene where each word appeared.

■ Practice speaking with shadowing (MAX)
Record your own voice line by line and compare with the original. With headphones, your voice plays in the right ear and the original in the left. Pronunciation scoring shows exactly which words didn't come through, and rhythm bars compare your timing with the original.

■ A shared pool of subtitles (Pro)
Subtitles created by users are shared in a pool — once someone transcribes and fixes a video, everyone can learn from it. New subtitles are created on the desktop web version (kotomori.app/shadowflow).

■ Plans
- Free: watch subtitles you created, word list
- Pro: unlimited access to the shared subtitle pool + folders
- MAX: everything in Pro + shadowing practice

Available in English, Japanese, Spanish, Simplified Chinese, Korean, French, and German.

## Version history (last 3 releases)

### 1.2 — 2026-08-14

ShadowFlow now runs on iPad. In landscape the video sits beside the transcript, so you can read along without the player taking over the screen.

Found a video with no subtitles? You can now request them — when someone creates them, they show up for everyone.

### 1.1 — 2026-08-08

Manage your subscription from Settings — change plans, restore purchases, or cancel without leaving the app.

Free sample subtitles are now marked in the rankings, so you can see at a glance which videos you can open right away.

### 1.0 — 2026-08-04

No release notes.
