The developers share technical decisions including custom UI gesture components, a custom walk-length selector, and a binary Codable format with a custom UnsafeCodable protocol to handle large datasets efficiently after SwiftData proved insufficient. The app is free with no paid features, aimed at gathering real-world feedback. ## Full article daily.dev links to this article rather than hosting it.
