App for helping non English speakers to help them learn English

The main idea is like this - We all know how non-english speakers struggle to learn English. In my opinion, it's because they don't get enough exposure to the language. Tons of other apps are available, like duolingo, but we need to combine all the other stuff in one place. The new app should have these features -<br><br>1. YouTube - We'll call it 'Video Zone' in the app, where the users can watch the YouTube videos. **But** - All the YouTube videos will be available in 3 ways - <br>a) English<br>b) Subtitles in English<br>c) Subtitles in user's native language<br>2. Podcasts - 'Audio Zone' is the name, where users will be able to listen to podcasts. <br>a) English<br>b) Subtitles in English<br>c) Subtitles in user's native language<br>3. News - 'News Zone' - where users can read news.<br>a) English<br>b) Native language<br><br>Obviously, there are some other features required to make this app useful, like in app dictionary, saving unknown words, daily word reminders and so on. But the main idea is to create an ecosystem, where people can learn English quickly.
