Do any of you iPhoneography buffs know of an iOS app that easily removes yellow and red tint or cast from photos? I've been using Color Manager for a long time. It works really well and is super easy to use. But it's 32 bit and will soon be useless if I upgrade to iOS 11 or upgrade my 6s Plus. It's no longer in the App Store. I've tried Camera+, ProCamera, and several photo editing apps, but none do the job. Thanks!
