Learn Spanish, English and dozens more languages through listening.

ReadJoy turns the books and documents you enjoy into bilingual listening practice. Start read-aloud and learn without having to follow the text on screen. Read along whenever you want, with the original sentence and its translation together.

SPANISH FIRST, ENGLISH AND MORE
Choose Spanish as your learning language and pair it with your native language. Listen to a Spanish sentence, hear its translation, then hear the Spanish again. Use the same approach to study English or another available language. Adjust speech speed and sentence playback order to suit your learning pace.

ReadJoy can use dozens of languages available through compatible Android text-to-speech engines. Language pairs, translations and voices depend on the translation service, your device and installed speech engine; not every language is available on every device. Some voices require an additional download.

YOUR LANGUAGES. YOUR LISTENING ORDER.
• Bilingual reading: the original sentence above, your native-language translation below.
• Read-aloud for original and translated text, using available speech-engine voices.
• Custom playback sequences, such as Spanish → your native language → Spanish, or English → your native language → English.
• Separate subtitle font sizes for the original and translation.
• Adjustable speech speed, sleep timer and reading controls.
• Import your own supported EPUB, TXT and text-based PDF files.

BRING YOUR OWN READING
Use content you own or have permission to use. ReadJoy is a reading and language-learning companion, not a bundled book library or a structured course. Scanned PDFs without extractable text may not work for translation or read-aloud.

CONNECTION AND VOICES
Online translation needs an internet connection and sends the text being translated to the translation service. Read-aloud uses your Android speech engine; some voices need a download or an internet connection. Machine translations can contain errors.

ONE-TIME PURCHASE
Buy ReadJoy once to use its reading, bilingual and read-aloud features. There is no subscription, free trial or in-app purchase. Google Play shows the price for your country before you buy.
