Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Kadō is an open-source, privacy-focused habit tracker for iOS that replaces fragile binary streaks with a non-binary exponential moving average score, inspired by the Android-only Loop Habit Tracker. It is built entirely with native Apple technologies (SwiftUI, SwiftData, CloudKit, WidgetKit) with zero third-party dependencies, and offers a polished, accessible experience with features like widgets, reminders, and iCloud sync. Its commitment to privacy, local-first architecture, and MIT license fill a clear gap for iOS users who want a modern, open-source habit tracker.

Target audience: iOS users, self-improvement enthusiasts, privacy-conscious individuals
