content:  Edit I just created an account after purchasing the Pro version and all my progress from the last three days was lost Maybe that shouldnt happen  I have one little complaint the audio will just stop out of the blue at one point and I have to activate my screen for it to start again then the timespan for which it plays decreases so in order to listen to it I would have to press the home button every 15 or so seconds or regularly unlock my phone which is not ideal for the experience.
