Great App but very slow – The Roll - Automatically organize and find the best photos in your camera roll Review

I love the concept of this app. It does what it claims .. No doubt about it. But it's disappointing to see this app freezing whilst scrolling through there pictures. I have iPhone 6S Plus so this app has pretty good hardware to get the job done but... I will maker it 5 star if they make it slick. #ChallengeforDevelopers
