I absolutely love this app and use it almost daily. I am a writer who has a terrible time focusing and concentrating. The binaural beats in this app, especially the wakeful super power help me more than I could have ever imagined. My one and only complaint is that this app doesnt run in the background. As soon as I get a text, alert or call it completely shuts down and I have to go back into the app and restart. Its incredibly frustrating to have to stop working to restart the app and search for my sound again. It really disturbs my flow. If this app could run in the background I would give it five stars. Please update it to do so!
