Great course, but app – not so much

First problem is that the app requires constant connectivity. Course content cannot be downloaded for offline study. Second is that the record feature routinely "hiccups", mangling your perfectly spoken words. I often have to repeat words several times before they are recognized correctly. In the upside, the course content (lessons, dialogs) seem to be very good.
