Cant save pictures to your device, only to Facebook or Instagram for some reason, and you get ads or prompts to upgrade every few seconds, no exaggeration. The pictures are decent enough, but, again, you cant even save them to your device directly, so you can only set the pictures as your wallpaper from the app.
