The practical workflow for shipping screenshots in every locale Apple accepts — what to automate, what to review by hand.
The structural design decisions in any high-performing carousel — caption position, device tilt, palette, continuity. With Headspace as a worked example.
A hands-on walk-through from blank canvas to App Store-ready 1290 × 2796 PNG, using Mokbi. Plus what to do for iPhone 16 Pro Max submissions.
