Kadō is a privacy-first, open-source habit tracker for iPhone and iPad. Instead of a fragile streak, it computes a non-binary habit score using an exponential moving average of recent completions, so a missed day only nudges the score down rather than resetting progress. The app is offline-first with local storage, offers optional sync through the user's own private iCloud CloudKit container, and requires no account, subscription, or telemetry. It is built natively for Apple platforms using SwiftUI, SwiftData, CloudKit, WidgetKit, and App Intents.
