using all the features on smartphone

I am enjoying your course. I only have internet access through my smartphone. Is there a mobile version available. I am still trying to use all the features of this course. It may be that only using the phone is making it harder. Also I tried the review feature but can not turn it off. But also can not fully utilize it. Turning the microphone on. Again This may be because of the phone but any suggestions would be appreciated. Thanks Tom
