Ratings and reviews

Beautiful app. Well thought out and responsive to my touch. And then there is Koko... I am humbled by the simple innocence and beauty of her soul. I'm not a religious person, haven't been for most of my life. But I am aware of a Power that I believe created and maintains this reality. Meeting a lioness in Central Africa many years ago who "asked" me for a belly rub made me aware of that Power. Now that I am old, Koko brings me close to that Power again. And I am grateful.

I have no words for this app (and I was a newspaper reporter for 17 years, so I was never at a loss for words). Get this app and expand your understanding of reality. I am humbled to have met Koko through this app.
