Having duo has giving me so much facetime with my family. I have recommended this app to my entire family. Successfully, ee are proud to be able to stay connected because we live so far away from each other. I would rate this app STAR INFINITY! Unfortunately, star infinity doesn't exist or Do it?!. The only problem with this app is nun. Thanks a bunch. Wish there was away to take pictures while facetiming, so many memories without the storage. God Bless
