Love the app. They have a large library of different articles you can read in the desired language, and you can translate every individual word and add it to a collection of flash cards to learn from. You learn so much faster it's incredible. I highly highly recommend trying it. And don't use it for a minute and quit, but really try going through the newspapers and teach yourself each word and dig into it. This is the only app that has this feature. We must support this gem.

Huge number of cards from and it paces you to move on to new sections once you're comfortable with what you've covered. (Edit): This was previously 5 stars, but some cards have the first sound of a word's audio cutout. I contacted customer service with a video and they gaslit me by saying the video doesn't show what it clearly shows) it's not constant or on all cards so it's manageable but I will keep this at 3 stars until it's fixed.

This is a great app but a bit difficult to navigate and missing a few features. I wish the app would show an example sentence by default instead of having to modify the card to add it, and also read the sentence when doing audible training. I also wish there was an easier way to retest learned words more often. And, as others have said, accuracy is a bit lacking.
