So far it sucks! It asked me what rewards I want to earn, and I clicked all of them except for lock my phone. But now, because I refuse to accept the unlock my phone reward, I can't even enter the app. Sorry developer, but I'm not an ostrich. I never wore a burqa for the last 2 years, and I'm not about to let you demand that I lock my phone. I don't ever let my phone out of my sight when I'm in public, I got no reason to lock my phone.
