Spotted in Prod is a community-driven showcase of iOS app design — designers post screen recordings and screenshots of interface details and interactions they've spotted in real, shipped apps.
Because everything comes from apps that are actually live in the App Store, you're looking at production-tested interaction patterns, not concept work — useful when you need a precedent for "has anyone actually shipped this."
Good for mobile product designers who want a feed of real iOS interaction and micro-interaction examples, and who like following individual contributors' posts over time.
It's community-submitted, so coverage is uneven and skews toward whatever contributors happen to notice — don't expect systematic coverage of any one pattern or app category.
