Show HN: Kadō – open-source habit tracker, with non-binary habit score, for iOS

Kadō is an open-source iOS habit tracker that uses a non-binary exponential moving average score instead of traditional streaks, allowing users to maintain progress even if they miss a day. The app prioritizes privacy with no account, subscription, or telemetry required, storing data locally with optional iCloud sync. Built natively for Apple devices using SwiftUI and SwiftData, it fills a gap in the market by bringing the Android app Loop Habit Tracker's algorithm to iOS as free, open-source software under an MIT license.
