Momkin

Momkin (from Arabic <a href="https://en.wiktionary.org/wiki/%D9%85%D9%85%D9%83%D9%86">ممكن</a>, "doable") helps you learn languages by visualizing what's being said. All you need is some audio file that goes with a subtitle file (supported format: .srt). You can download those files with apps like <a href="https://newpipe.schabi.org/">NewPipe</a>, but you can also create them yourself with programs like <a href="http://www.aegisub.org/">Aegisub</a>.
