Ratings and reviews

I wish you would spend less time with annoying floating elephants and fix your atrocious pronunciations.

The app is great, I just wish the subscription was more affordable or that you could give discounts every now and then, like Duolingo does. If the yearly sub was paid monthly instead of the full price all at once, I would definitely subscribe. Suggestion: it would be nice if we could save the story that the AI creates for us with the words we learned. This would help us to retain the words better, imho. Or a simple copy button would be great, too.

This is the best flashcards app EVER made!!! I've learned over 300 words and I am really really grateful for this app and for those who created this. It's useful, funny, simple but still with many functions to improve your learning journey, like the power to change the voice that says the words. I just wanna thank you! I recommend this app and for sure its premium version. If you buy it, you won't regret that, because it'll be a good investment!!! ♥️
