I've been using this for a little over a year and find it to be pretty useless. But it is good if you can get it to work, to quickly swipe right or swipe left to view a large number of photos in a hurry. But you have no control over your photos or where they go or where you keep them. All of its most useful functions are unpredictabe, and are also awkward and slow to use, such as rename, move or edit. This seems intentional. They don't want us to do that. Often a renamed pic will disappear.
