You can already do almost everything through Iphone's / Android browser- only, not that comfortable strictly due to size restrictions. On IPAD's (well, any pad...) big screen eFront really shines due to icon optimized interface that makes natural to work inside it.
The screen size is the biggest problem on IPhone - and this problem cannot be fixed through an app.
On the contrary an app can provide a convenient way to check your learning status and communicate (it takes less time and less effort...)
Your suggestions on this topic is always welcome
