I got this app thinking I could gradient my photos, but I have no idea how to do that, you can’t add photos onto your wallpaper as it says on the display screen before you download it otherwise very easy to work but I wish it would come with instructions or some thing to help you put it onto your Photos. I do wish you could use more than two colors and that there was more to it overall I really like the wallpapers and I wish that you could save it if you want it for later on the app instead of having to use your data in photos
