What does “bilingual reading” mean in SurfEnglish?
Every translation is placed directly below its own sentence or paragraph, so the English and your language stay on screen together. You read the original, glance at the translation when you need it, and keep going — instead of copying text into a translator app.
How do I translate a sentence?
Swipe right on it. The translation slides in beneath the original. You can translate one sentence at a time or switch to paragraph mode in Settings, and choose between the cloud engine, the on-device engine and AI Natural Translation.
What are language chunks?
Groups of words that work together — phrases like “a growing number of” or “get used to”. SurfEnglish highlights them in the original text after a sentence is translated, automatically or on demand, and explains each one, so you see how English sentences are built.
Does double-tap lookup include pronunciation?
Yes. Double-tap a word to get the meaning that fits the sentence, its part of speech and pronunciation, and open the full entry for more senses and examples.
Which languages can it translate into?
21 languages: Simplified and Traditional Chinese, Japanese, Korean, Spanish, Portuguese, Vietnamese, Indonesian, Thai, Hindi, Arabic, French, German, Italian, Russian, Turkish, Polish, Dutch, Ukrainian and English (US and UK). The app interface itself is available in 12 languages.
Is SurfEnglish free?
Yes. The feed, reader, browser, games and on-device voice are free every day, with daily limits on actions like translation, chunks and word lookup. SurfEnglish Plus raises those limits and adds automatic feed translation.
Does it work offline?
Partly. The on-device voice and the local translation engine work offline, and your saved articles and learning library are stored locally. The live feed, cloud translation, language chunks and word lookup need a connection.
Can I read any website bilingually?
Yes. Open the built-in browser, search or type an address, and keep up to 24 tabs. On supported webpages, sentence translation, language chunks, word lookup and read-aloud work the same way as in the feed.
Do I need an account?
No. SurfEnglish works fully without an account. Sign in with Apple only if you want your topics and custom feed definitions to sync across devices.
Which devices are supported?
iPhone and iPad with iOS or iPadOS 18 or later. Get it on the App Store.
