I have recently started using your app. I was planning in using it to learn a new language as I commute to work and back home. But since I am almost always the driver and because the app requires a lot of manual (read, using one’s hands) use, I am not being able to use it as much as I intended.
Therefore, it would be great if the app would have the capabilities to be used hands-free. One way I can think of it, for example, is by having a good voice controlled interaction with the app.
