Kadō

Kadō is a privacy-focused habit tracker designed for iPhone and iPad users seeking to build long-term routines without the punitive aspects of traditional streak-based systems. Instead of relying solely on streaks, Kadō introduces a non-binary habit score based on an exponential moving average of habit completions, ensuring that missing a day gently adjusts progress rather than resetting it entirely. Streaks are still visible, but the habit score provides a more forgiving and realistic measure of consistency.

The app operates offline by default, requiring no account for use and storing all data locally on the device. For users who wish to sync their habits across devices, optional iCloud integration is available, utilizing Apple’s CloudKit private database so that data remains private and inaccessible to the developer or third parties. Kadō is built natively for iOS, leveraging technologies such as SwiftUI, SwiftData, WidgetKit, and App Intents, and offers home-screen and lock-screen widgets for quick access. The interface is designed to feel like a first-party Apple app, with accessibility features including full Dynamic Type support, VoiceOver labels, Dark Mode, and adaptive semantic colors. The app is available in both English and French, with the French translation crafted by a native speaker.

Kadō supports a variety of habit scheduling options, including daily, specific weekdays, N days per week, or every N days. Users can track binary, counter, or timer-based habits and can switch between these types without losing existing data. The app displays habits in a matrix view, allowing users to scroll through history and tap on individual days for more detail. Reminders are handled via per-habit local notifications, which are scheduled on-device and never routed through external servers. Import and export functionalities include lossless JSON round-trip, with CSV export and import from Loop Habit Tracker, Streaks, and generic CSV files planned for future releases.

Kadō is open source under the MIT license, free to use without ads, subscriptions, or paywalled core features. The only monetization paths considered are a one-time tip jar and a possible optional cosmetic "Pro" tier in the future. The source code is publicly available, and contributions are welcome. Kadō is intended for individuals who value privacy, accessibility, and a more compassionate approach to habit tracking on iOS devices.
