content: This app is really helpful for the ones who dont stay focused.... But I would recommend this app or the appmaker to produce more Beautiful sounds of nature like those of ocean waves or the sound of the rain drops... And moreover I want to add one more thing.. That is any person could get out of this app at any time by just pressing off to the middle button of any android phone and can get busy with even messaging.. So whats the use of this app It could have been set up like if someone hit to another home like the home button or other there could have Alarm warning sound which couldnt be stopped... Cuz u know its all about focussing
