Awesome Language Learning App But..

I am using this app for my Spanish and it is VERY helpful. I LOVE the SRS feature. However, the pronunciation feature is able to be used on the initial word on the front of the flash card. If it could be used on the word that gets revealed, that would be AMAZING; because sometimes you don’t want the Spanish word first, you want the English word, THEN the revealed Spanish word with pronunciation. If you could make this change, that would be AWESOME! Thanks! :)

Developer Response ,

Thank you very much for your feedback.

Many users have been asking us to implement reversed learning too so we will definitely implement it in the near future.

by and large it is great.

Free, powerful, best backers, limitless, even science-aristocracy and bla bla bla. But it is not hands-on, if you need power, you have to put forward sacrifices. It is challenging to become familiar with the process. How implement google sheet, how to make a connection between google drive and ulangi, even how to read your cards. But after all these, you finally will become independent of all paid app.

must sign up

another app that makes you sign up... for flashcards? Yeah, how about no. 1 star.

update: I tried the guest sign in after the developer suggested it. This app is still not my thing, the UI is too cluttered for me, but some people really dig it so I take back my one star. 5 stars for the support.
