Memrise is another solid language learning app with a few extras for improving your polishing your mind palace.
You can select how intensive you want the language training to be, starting with basic or opting for an intermediate or advanced level. The app then uses pictures, multiple-choice answers, and other language exercises. I didn’t spot any voice training while trying it out, however.
Its signature feature is Mems, which is what it calls user-submitted images that are supposed to help you remember specific terminology. It will help if you’re a visual learner, but those who remember best through audio or other means are out of luck.
Along with language, there are courses for world capitals and other random topics that could be useful for impressing others at your next cocktail party.
The premium subscription is $59 per year, and it gets you data performance analysis, more lessons on difficult words and some kind of “motivational tools.”
Because the details are rather murky, I’d recommend sticking with the free option until you come across a reason that makes it compelling to upgrade.
