Save your money!!!
I wish I would have truly believed all the reviews that Id read. I could not believe that an App would not allow you to search (especially when you can search with the Periscope App on iPhone!). $1.99 totally wasted. Unable to search for users or to save them to receive alerts when they go Live. Go to Katch.me/UserName instead. While you cant watch it Live, at least you can watch it from your iPad.
