zeroStudy

Reinforce now includes words you save from web articles. With the optional zeroStudy Chrome extension on your computer, highlight a word or phrase on a web page and save it. The word then appears in Reinforce on your phone, together with the page title and the text around it. On each card, you can open the original page, tap other words in the saved text to save them too, or show a translation of the text. Translation is a Pro feature, the same as for video subtitles. Reinforce by Source now lists each web page as its own source next to your videos, so you can practice the words from one article at a time. Manual Entries now contain only words you added yourself. Vocabulary cleanup now shows the web page and saved text for words that came from web articles.

Turn the YouTube videos you already enjoy into a language-learning routine. zeroStudy brings interactive subtitles, vocabulary capture, and spaced repetition together, so watching, understanding, and remembering flow in one place. LEARN WITH YOUTUBE • Paste a YouTube link and watch without leaving zeroStudy. • Follow interactive subtitles as the video plays. • Select a word or phrase to understand and save it in context. • Continue recently watched videos and track your daily immersion progress. REMEMBER WITH REINFORCE • Review vocabulary with spaced repetition at the right time. • Use active recall to build durable memory. • Hear pronunciation and revisit the original sentence. • Add your own words and phrases manually, with optional AI Auto Fill. • Track your streak, retention, and learning progress. KEEP YOUR LEARNING CONNECTED Your vocabulary and progress stay synced across zeroStudy. The optional Chrome extension gives you another way to collect vocabulary while watching on desktop, but it is not required to use the iPhone app. Watch what you enjoy. Save what matters. Reinforce what you want to remember. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
