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

Kadō is an iOS-only habit tracker that replaces binary streaks with a non-binary exponential moving-average habit score, preserving progress after missed days. It stores data locally with optional iCloud private-database sync, offers JSON/CSV export, supports widgets, Siri, Shortcuts, and flexible scheduling, and is released under an MIT license without accounts, subscriptions, or telemetry.
