We currently support iPads, iPhones, and Android Phones, but not tablets. We spent a great deal of time trying to optimize Fluenz for Android Tablets, however, there are far too many devices out there that run Android and we haven't been able to make the program run to our level of standards. As a small educational outfit, we hope you can understand our predicament here.
BTW Andy, I would be more than happy to beta test whatever you have if that would help. Even if it's not perfect, it might be adequate for my purposes, For example the conversation workouts wouldn't be of much use anyway on a train, plane or bus. I'd save them for when I'm home with the laptop. Thanks for all you do, I'm sure it's beaucoup de travail!
