What the mobile apps can open
On both iOS and Android, start with YouTube or a compatible website whose video player exposes built-in VTT or SRT subtitles. The same idea works across 1,000+ compatible sites, although caption availability depends on the exact video. A site can be compatible while one of its videos has no usable subtitles.
Netflix, Prime Video, HBO Max and similar native streaming apps do not accept a browser extension inside their players. For those services, use our desktop extension. Loading your own subtitle file into a detected video player is also a desktop feature; it is different from playing a mobile site that already supplies captions.
A study loop you can repeat on either phone
Choose a video at your level, listen to the original and keep the second subtitle line as a check. Tap an unfamiliar word or phrase for a contextual AI explanation. Replay the line, use auto-pause and repeat it in Shadowing. Dictation reveals what your ear missed; Speaking can help you inspect your own recorded words where it is available in your app version.
Finish by saving a small number of expressions and reviewing them with FSRS-6 flashcards. You can also continue with books and articles from the CEFR-level Read catalog or your own PDF/EPUB, translating selected text in context. A varied routine is easier to sustain when each session has one small, clear task.
- Day 1: understand a short captioned video.
- Day 2: dictate and say two useful lines.
- Day 3: review saved words and read a short text on the same topic.
Choosing among popular video-learning tools
If you are comparing Language Reactor, Trancy, Migaku and Lingopie on mobile, begin with your own device and source of content. Do you need a particular YouTube channel, a course website, a curated show library or an established flashcard workflow? The names overlap in search results, but those are different decisions.
Our answer is a flexible study routine around YouTube and compatible captioned websites, with separate desktop coverage for streaming and courses. We publish individual comparisons with Language Reactor, Trancy, Migaku and Lingopie so you can inspect the relevant workflow rather than rely on a single winner claim.
Keep your vocabulary portable
Saved words can be reviewed in LinguaCap. With Pro, you can export vocabulary directly from the phone or your account on the website if you prefer to maintain an Anki collection. Try a small export to check fields and formatting before relying on a large deck transfer.

Yes. Our app has App Store and Google Play listings. Check each store for your device’s current compatibility requirements.
Can I use the same sites on both phones?
The shared mobile approach is YouTube and compatible websites with built-in VTT/SRT captions. Exact behavior depends on the player and subtitle track on the page.
Is this the same as installing the desktop extension?
No. The desktop extension covers additional streaming and course sites and local .srt/.vtt upload. Mobile apps use their supported video and caption workflows.
