However, in my personal experience, solitude is a state of being I do not wish to share with others when I'm experiencing it. It's a place I go to get away from the bombardment of thoughts and ideas and senseless chatter we all suffer through (although some enjoy it more than others). It's a place for quiet reflection and meditative concentration on self improvement and pursuit of happiness. When I want to be alone I want to be absolutely alone because each time I emerge a new person.
Then again, take what I say with a grain of salt; I don't even have a smartphone for precisely the reasons above. I view the level of mindless connectivity we all have with each other now to be somewhat insane.
All that said, if you can get more people to enjoy time by themselves, even if it is with the crutch of a smartphone, I would consider this app the methadone to social media's heroine. You have my blessing =].
