User reviews

Amazing for learning Spanish

This is exactly what I have been looking for in having English and Spanish side by side. The reader is really helpful to hear how the Spanish words are pronounced. Ipad version is much easier to navigate than android phone version. Love books are already built in. I can’t believe this is free, I would happily pay for this app to make language learning way more real and useful than many other apps on the market. Thank you for creating and sharing! Would love OpenDyslexic font option as well.

Useful and simple

I’m enjoying using the app. The recent dictionary update has been improved with context specific definitions. This is likely book specific but for my use cases it’s much better. The UI is simplistic but works. The added narration voices are much better as well but not totally natural.

抱歉,服务器当时出了点问题,已修复

Good, could be better

The dictionary is very poor, but otherwise the concept is excellent

Response from developer

We updated the dictionary to use LLM to provide dictionary with context. Hope you'll lke it.

Nothing happens.

I tried to find your support page. I couldn’t and that’s why I’m doing this in reviews.

Is there something other than the app that I need to install before it starts working? I can’t select any books or articles. I appreciate your help with this.

Response from developer

Sorry, for certain language pairs, book selection was limited. In recent 2.0 publish, LLM translation is introduced and if you can give it a try, it should be a lots better.
