I found Soundwise to be intuitive and my learning curve is very small. As a new user, I got pop up suggestions to guide me to work my way through the app to put up my content easily. I like the mobile app too. I know for sure that when my customers buys an audio course they would have a good experience learning via the soundwise app. The interface look is simple, I do think they can improve on the colour palette of orange they use and add paypal payment option. Another suggestion would be to provide a bulk upload option to the essential plan of maybe up to 5 files per time. The app seems to be promising, look forward to even better improvements as the app evolves.
