Your developer page is not your whole portfolio
The App Store is excellent at selling one app at a time. It is less useful when someone wants to understand the studio behind several products, compare categories or discover the next relevant tool. A separate catalogue gives every app a stable page and gives visitors a reason to keep browsing.
Start with a URL
Use the public App Store developer page as the source for the first product list.
Curate the result
Include the products you still support, assign useful categories and correct the copy.
Give each app a home
Add product URLs, screenshots and a clear App Store call to action.
Make it crawlable
Export static pages with internal links and structured product data.
A catalogue compounds distribution
Every product page can answer a different search. A category page can introduce a related product. A launch post can link to the catalogue instead of disappearing in a feed. The result is a small studio directory that helps both people and search engines understand what you make.
If you have more than one app, build the portfolio once and give every product a better path to discovery.
