About this prototype

An independent visual concept, directed by Nick Calo and designed and built with AI assistance. These are native SwiftUI captures using sample content and local interactions. The app is a portfolio prototype, not a released service.

Native SwiftUI tab bars use Liquid Glass on iOS 26 and later, with standard system bars on earlier supported versions. Built for iPhone with iOS 17 and later.
