Nice, well you can download each audio file you convert to your device at any time. I found a single file didn't make sense as you lose your place in it easily. Instead splitting each chapter into a file seemed to do well. But, you really do want a listening app. Otherwise it get harder to share and listen to on your phone. So far I created a listening app as a PWA for the time being.
