ImSorryDaughter! ,


This is probably my first time writing a review on any app I ever downloaded out of my many years of using Apple products and downloading apps and all I can say is this app is perfect. I've been searching online and constantly downloading different apps trying to resize pictures to my perfect background but sadly I never got much luck in finding an app to help me with that until I came across this one. Other apps that actually did let me resize my photos forced me to use their color backgrounds and the colored backgrounds never matched up to the exact color in my picture but this app lets you extract the color from your picture and use it as the background when you resize your picture so it helps so much! 5/5 and I love it!

This is really good, eh. ,


Ever since apple made my photos that I tried making my backgrounds zoomed in Ive been so sad and angry, but this fixes it PERFECTLY. Amazing
