Readlang is great for when I'm able to pay attention to the screen, but I also like using ClozeMaster for hands-free learning.

I set the whole Fluency Fast Track to Radio Mode and have it read a Spanish sentence out loud (in a robot voice, but that's fine), then read the English translation, then read the Spanish sentence again before moving on to the next, all hands-free.

This is great for being able to get some listening practice in while I'm doing chores or whatever.

It might be nice if ReadLang had some sort of feature where it could go through my flashcards and read the Spanish word out loud, then read the English translation of the word, then maybe the Spanish context sentence (and then maybe a translation of the whole sentence?) and then move onto the next one without me having to push any buttons.
