Great Grader and light balancer for iOS videography!
Dont get sucked in by all the B.S. Sharing "video filter" crap apps out there. If you want quality, you need one of the two iOS editors, iMovie or Pinnacle, a few cool filters, and especially this. Get it in the shot, learn about photography and lighting, and you can do so much with the work using Saturation, White and Color Balance and Tinting, and some tilt/shift...This one DOES need to allow the highest resolution possible, and on certain devices it can fail to render...but it is the best Color grading App for iOS.
