Comments on Duofolio for Android

★★★★★ Nice app 😄 But will be better if have been option to choose your native language and language to what translate.

★★★★★ A pretty good app and a great idea. I tried using it for Spanish and while it did work, it didn't recognize a lot of words. If the dictionary size is expanded upon that would make it very useful. It also doesn't recognize inflection which can be confusing for new learners. It's not a bad app just needs more work.

★★★★★ In short: Great app. Does very well what the app announces it does. Really good app to read pubs. Font size and line spacing are customizable. There is a dark background mode. Translations are made with Google Translate. The app does what it's meant to, and it does it well. I don't think it required any other permission besides accessing the files to find the books. Would some extra features be useful ? Sure ! Bookmarks and a quick way to go back to the index would be very useful.

★★☆☆☆ As Foss enthusiast I don't want to write bad review, but this app is garbage. Not only it doesn't support PDF and mobi formats, even epub isn't working. I have tried dozens of pubs, from different sources and Nada, the app just shows title and loading /0. Librera and other readers are working just fine, the problem is within this app. P. S also the app constantly tries to connect certain IP addresses, I wonder why?😐

★★☆☆☆ No helpful tutorial, no help page, translation doesn't work ever, just asks me if the right language is selected. Basically useless without the polish of helping the user understand how to use it. I tried it with epub of English books, trying to learn Spanish.
