Super simple to use and a very clean user interface, with options enough for your average language learner. (Super tech geeks will want more customization and anki integration with next leval deck making, but for someone like me who just wants to get on with it and not make flashcards my life's work, I find the included deck making more than adequate.) The AI subs are as great as the new technology allows and if there's an error it's a wrong word that's easy to spot and I'm sure will improve, and it's a vast improvement over traditional subs.

The program also replaces other text dictionary/translation apps as well. I have dictionariez in addition because they hav different dictionary options and they integrate with anki, but honestly, this is sufficient to give you immersion in all media with spaced repetition vocabulary review: it's a one-stop shop.

Plus it's free and the pro version is a fraction of the cost of other paid apps, so you can't go wrong.

But mostly, I love the interface. Good job!
