Kadō open-source iOS habit tracker ships with non-binary score and offline-first storage
Kadō, an open-source iOS habit tracker, is now available on the App Store, featuring a non-binary habit score, offline-first storage, and no account or telemetry.
For engineers, Kadō offers a reference implementation of a privacy-first mobile app: no accounts, no analytics, and local storage with optional iCloud sync. Its non-binary scoring algorithm (exponential moving average) is a departure from fragile streaks and could inform similar features. The MIT license allows full code inspection and reuse.

Kadō is an open-source (MIT) iOS habit tracker with no account, no subscription, and no telemetry.
It uses a non-binary habit score based on an exponential moving average, so one missed day doesn't wipe progress.
Data is stored locally via SwiftData, with optional iCloud sync through the user's private CloudKit database, and export/import in JSON and CSV.
