Make a 15-second App Store Preview video for [APP NAME], exported in an App Store-supported portrait video format. Build it from the app's real screens running on a sleek modern iPhone, with one short, confident benefit headline and the app's name, and leave the edges clear because Apple crops and overlays previews on different devices. Keep it clean and on-brand in the app's light UI, show the core features with realistic sample data and real-looking people, put no prices or "AI" buzzwords in the video, and deliver the final video plus a variant or two to A/B test. Make it a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a résumé. Go all out.
