Free specialist ASO course · 10 lessons
App Store screenshot optimization course
Turn an unclear screenshot sequence into a documented creative proposal. Ten practical lessons take you from audience research to a complete storyboard, listing comparison and experiment handover.
Your project: a review-ready screenshot proposal
Bring an app and current store listing, or use the fictional Trail Notes hiking journal. You will keep a baseline version, develop an alternative, connect every message to product evidence, and export a review pack. Allow around seven to eight hours including assignments; research on your own app may take longer.
Three tools, one saved project
Listing Studio previews your copy and images. The Storyboard Builder organizes messages and proof. The Metadata Comparator documents what changed. Export a backup to carry your project to another browser.
Who this course is for
App marketers, founders and designers who need to explain creative decisions and prepare assets for review. You do not need a paid ASO platform. For broader keyword, measurement and acquisition foundations, use the 60-lesson ASO course.
