Anybody using the SAGA lifelogging APP?

Hey guys, I had read on mfp's website about a week ago that there was a new app called SAGA that has functions that support and sync with MFP - it required the latest version of IOS software to download - after jumping all of the hurdles and updating my phone, I am having trouble logging in to my app store (beside the point) I'm really excited about the app and the suspense is killing me. Have you downloaded/used it? It has mixed reviews on apple's website but the negative reviews might be from people who don't use MFP and otherwise might not see the benefits in the features of SAGA. Just wondering if anybody on here has used it, what you thought/liked/didn't like. Thanks!
