App Install Banner (3D Gradient Phone Mockup)
The tilted phone mockup plus left-side negative space is the classic install-ad layout that survives every text overlay — you get an on-spec 1.91:1 banner without ever opening a design tool.

prompt
Create a horizontal app-install banner for {app_name}, a {app_category} app. Composition: a floating smartphone mockup in the right third, tilted 15 degrees with a soft drop shadow, its screen showing a clean abstract UI in {brand_color} tones — simple blocks and cards, no readable text. Fill the left two-thirds with a smooth {brand_color}-to-dark gradient, with subtle 3D geometric shapes and light streaks pushed toward the edges to suggest speed and ease. Float one small star-rating badge beside the phone. Modern SaaS aesthetic, crisp edges, gentle depth-of-field glow. Render in 1200x628 landscape (1.91:1) for social link ads, keeping the left half visually clear for a headline, subline and download button that will highlight {key_benefit}.
Variables
This prompt uses the variables below. Fill them in when you hit Copy — anything left blank keeps its {placeholder}.
- {app_name}Name of the app
- e.g. OrderGo 點餐通
- {app_category}Category of the app
- e.g. restaurant table-booking
- {brand_color}Primary brand color
- e.g. teal
- {key_benefit}Key benefit the overlay copy will highlight
- e.g. book a table in 10 seconds
