LangTurbo is a podcast player for people learning a language. You listen to shows made for people who already speak it, and read along while they play.
Why podcasts?
Staying interested is most of the work in learning a language, and it is much easier to keep coming back to a show you like than to a textbook. Podcasts are also real speech: people interrupting each other, trailing off, and using the words they actually use.
How it works
Choose the language you are learning, then find a show about something you care about. When you play an episode, the transcript follows along one line at a time, with the English under each line.
If a word stops you, tap it. The episode pauses and you get what the word means in that sentence. Every word you have not marked known is highlighted, so you can see at a glance what is still new, and the same card marks a word known once it no longer is.
When you first pick a language you can tick off the common words you already know. It is optional, and it tells the app which words to leave alone.
Can beginners use it?
It works best once you know some of the language, when you can follow a sentence if you get help with a word or two. It was made for the intermediate plateau, where textbooks have stopped helping and real speech still feels too fast. If you are just starting, try slower shows or ones made for children, and lean on the English line.
What it is based on
The main idea is comprehensible input: you pick up a language by understanding things said in it. Meeting words inside whole sentences helps them stick better than learning them from a list. And motivation has a lot to do with how far people get, which is why the app starts from shows you would choose anyway.
