For example, I participated in Explore, a Canadian immersion program that offers a chance to live in Québec for five weeks and really improve your French by speaking it day-in and day-out. Targeting such programs to their users could be a great value add.
I installed the Android app right now, and seems to be even better than their iPhone app (you can type directly the translations instead of choosing between a closed set of words). It's a fantastic app, highly recommended to learn a new language.
It will be great if they could add a way to chat with other users like in verbling.
The site and application are really important missing step between a language beginner which doesn't know the language enough to be able to improve it organically by random reading and conversation, and an intermediate speaker that can go forward on its own.
I would really recommend this tool, especially in combination with real language course. The app is great, but the site is still better, since the some things are missing from the app. I hope the app will catch up to the site usefulness, since it is so much easier to use when commuting.
