The biggest pain point of listening audio books is to have the standard play, pause controls which are difficult to touch e.g. when you are driving a car.
Gudio allows you to use swipe gestures to play, pause, forward 30 seconds, backward 30 seconds while you focus on the road or are walking, running etc
The biggest pain point when listening to audio books is that you can't save the parts you thought were awesome or very useful. Yes you can bookmark it but a single point bookmark is not enough. You need to tag the entire piece of book that you found useful
Gudio's purpose is to make your "On The Go" experience awesome while listening audio books, podcasts and other useful audio content.
