Use a constrained visual system
Choose one type scale, one or two background colors, and a repeatable screenshot frame. Constraints make a set look intentional and make later updates faster.
Work from real screenshots
Prepare clean captures first, then use a composition tool for the supporting text and layout. Keep captions subordinate to the interface, and make each image explain a distinct capability.
Export with a review step
Use the Screenshot Generator to create a consistent composition, download the finished files, and verify the output dimensions, readability, and current Play Console requirements before upload.
Google Play requirements can change. Verify current details in the official Play Console preview-assets guidance and in your Play Console before publishing.
