Replace five screenshots (750 x 1334) with shots of your iPhone app.
Using Sketch, edit or add to five artboards featuring your screens. Choose from a silver, gold, black, or rose gold iPhone 7 to frame your shots.
With some help from the Sketch Replace Images plugin, Sketch generates all the sizes required by the App Store for iPhone 4, SE, 6/7, and 6/7plus.
Enjoy! 👊
