About this app

TwinTongues turns reading into a powerful language-learning experience. Listen to audiobooks with synchronized subtitles in two languages at the same time — follow the original voice while reading the translation, or do the opposite. No more switching between apps, tabs, or dictionaries.

WHAT MAKES TWINTONGUES DIFFERENT
Most language apps teach you words in isolation. TwinTongues teaches you language the way you actually learn your first one: through stories, in context, with rhythm, emotion, and natural sentence structure. By pairing professional narration with synchronized bilingual subtitles, your brain links sound, meaning, and form on the fly.

KEY FEATURES

- A growing catalog of bilingual audiobooks in English, Spanish, French, Portuguese and Italian — including timeless classics now in the public domain.
- Instantly switch between the original voice and the translated voice without losing your position.
- Word-level synchronized subtitles that scroll with the narration so you never lose track.
- Automatic progress saving across chapters and books, on every device.
- Background audio playback with full media controls from your lock screen and notifications.
- Adjustable playback speed to match your level — slower while you learn, faster as you progress.
- Clean, distraction-free reader designed for long listening sessions.

WHO IT'S FOR

- Language learners at any level — beginners can lean on the translation, advanced learners can focus on the original.
- Readers who love classic literature and want to enjoy it in two languages at once.
- Commuters, walkers, runners and travelers who want their downtime to actually move them forward.
