concept
One phone screenshot, one glow-up story: a fitness-tracker comparison screen with two side-by-side photos (or a 2×2 grid) of the same person, same angle, same place, labeled "Day 1 / Day 365", "Before / After" or "Lv.1 / Lv.99". Chinese or English UI, dark or light mode, date labels and stat lines all render cleanly.
How to prompt: start with progressconcept,, describe the app UI (dark/light, language, title, tabs), then the left (Before) and right (After) photos separately — the same person's look and age (e.g. an adult man aged 22), pose, location and exactly what changed — and finally list every on-screen text in quotes. For a grid, write "four progress photos in a two-by-two grid". MOSS loves long prompts — the more detail the better.
