At a glance
Install our Android app from Google Play to study YouTube with dual subtitles and use compatible websites that provide built-in VTT/SRT tracks. Tap a word for its meaning in context, replay a line, practise through Dictation or Shadowing and revisit saved vocabulary. Site and caption availability vary by video.
Use the video you already planned to watch
Open a YouTube video inside LinguaCap, select a clip with captions and follow the original line before checking its translation. A tap on an unfamiliar word brings up a contextual meaning, pronunciation and examples. This keeps the explanation next to the moment you heard the word.
The built-in browser can show dual subtitles on compatible video websites with standard VTT or SRT captions. We support 1,000+ compatible sites in this sense; a particular page still needs an accessible track and a supported player. Our desktop extension is the route for Netflix, Prime Video, HBO Max and similar streaming services.
Train listening and pronunciation on Android
Replay an individual line and slow playback when the speaker is too fast. In Dictation, type what you heard and compare it with the subtitle. Use Shadowing to follow the speaker’s rhythm and intonation; auto-pause and repeat help with difficult phrases. Where the Speaking mode is available in your app version, record your voice and inspect the recognized words.
A useful session is short: watch two minutes, choose one line you could not understand, complete the dictation, repeat it aloud and then watch the same passage again without looking at the translation. This gives you a clear check on progress.
Build a vocabulary habit that survives the video
Save words and phrases worth using again. Our spaced-repetition cards bring them back over time; the FSRS-6 scheduler responds to your review answers. The app also keeps studied videos with their transcripts and timestamps so you can return to a familiar passage.
If you search for Language Reactor on Android, Trancy, Migaku or Lingopie, compare the task you want to do on your phone. Our Android workflow starts with your captioned YouTube clip and continues into listening practice and review. For a fair comparison, try the same short video and see which app helps you remember a phrase the next day.
Keep desktop and phone roles clear
Use Android for YouTube and compatible embedded-caption sites. On desktop, our extension covers a broader set of named services, supports uploading your own .srt or .vtt subtitles when a player is detected and translates Spotify lyrics. Android does not change the limits imposed by a streaming service’s native phone app.
Start with a free video that already has captions, then test the features you need before planning a course around them. If you use Anki, Pro vocabulary export is available from the phone or web account; check a small export first.
Frequently asked questions
Where can I download LinguaCap for Android?
Use the Google Play link on this page. The store listing is the source for current installation and device requirements.
Does it work on every video website?
No. A video needs an accessible built-in VTT/SRT subtitle track and a compatible player. Test the specific page you want to study.
Can I load an SRT file into the Android app?
The workflow described here uses captions supplied by the site. Uploading your own .srt or .vtt to a detected video player is a desktop extension feature.
