Might be good, might not. I finally decided to give this app a try, and lets just say that this app is NOT meant for those outside French-speaking countries. I maxed out my capacity of reading/speaking French the moment I went to the website to buy a V-book (because you have to buy the proprietary format, PDFs of books you got from other locations wont work). No biggie, just means I gotta learn more French... until I saw the kiss of death for this app. I dont want to pay more than the actual book in conversion fees between USD and Euro, and I have a feeling I'd be doing that here... definitely needs work if it wants to reach a bigger audience.
