"title": "Still new but loving it!",
"body": "This app is great ! It’s pretty overwhelming at first because of all the words being thrown at you within the sentences but I find myself remembering more words because of this app I listen to media in my target language. Focusing on the underlined words makes it helpful and the fact that you can select to learn individual word is wonderful. Just like anything, you have to keep at it to get results. I’m very excited about the listening update! Thank you for making this app! It’s a wonderful addition to my language learning rotation",

I find the sentences to be unique and memorable, making it more likely for myself to remember new words in context. The app is still fairly new, and continues to improve in small ways over time.
