I used this app all the time to find the best profile pics and as far as I can tell, its the only app that has real facial recognition science behind its ratings. That said, Im giving it 1 star because it hasnt worked at all since the iOS 8 update. It appears to be a simple UI bug but they havent bothered to fix it (despite an email telling me they are working on it). Come on guys, its been months now and a lot of people paid for your apps. Have some business ethics.
