Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 6)

Kadō is a privacy-first habit tracker for iOS that replaces fragile streak counters with a non-binary exponential moving average score, inspired by Loop Habit Tracker. It is fully native to Apple's ecosystem with SwiftUI, SwiftData, WidgetKit, and optional iCloud sync, and maintains a strict zero-telemetry, no-account policy. The project is interesting for its thoughtful combination of an established algorithm with a modern, open-source, and privacy-respecting iOS implementation.

Target audience: iOS developers, privacy-conscious consumers, habit-tracking enthusiasts
