Yes, it works pretty well. It just took a while for the entirety of my photos to back up since i have over 10,000 it's nice to back them up and delete them off your phone. Tell me if you have any other questions
One of my friends downloaded it and uses it religiously. He stores all of his photos and videos on the Google Photos app rather than in the "Photos" app on the iPhone, and apparently it saves you a bunch of storage on your phone. I haven't tried it, but I've used the Google Drive app (which is similar), and I think it's pretty convenient if you're looking for a way to store your photos that doesn't eat up all your storage. You have to have a connection to access your photos, though.
It's great. Your photos get automatically saved (great size also). It allows you to create albums and add dome effects if you want to. Some times the system automatically creates enhanced versions of your images that look really nice.
It is worth having it. Make sure that you are connected to wi-fi when you first use it (in case you have a lot of photos saved to your phone).
UNDERRATED app I have over 30,000 personal photos uploaded. it is so easy too.. there's a feature will it will clear the photos that have already been backed up on your phone so you clear some space off your phone
