Kadō - Privacy-first habit tracker with non-binary score
Show HN: Kadō – open-source habit tracker, with non-binary habit score, for iOS
Kadō is an open-source iOS habit tracker that redefines progress tracking with a non-binary habit score, inspired by Loop Habit Tracker. Unlike fragile streaks, Kadō's exponential moving average gives you a resilient trend that survives occasional misses. Your data stays private—no account, no analytics, no third-party SDKs—with optional iCloud sync through your own CloudKit database. Built natively with SwiftUI, SwiftData, and WidgetKit, Kadō offers widgets, reminders, flexible schedules, and full accessibility. Available on the App Store, it's a fresh, privacy-first alternative for iPhone and iPad users who want a smarter, more forgiving habit tracker.
One missed day doesn't wipe your progress. You see a trend, not a fragile chain.

I love this. My only gripe is that I wish habit trackers were more evidenced-based for some real accountability. "Work out 25 minutes" is such an easy habit to fudge by showing up late to the gym, but if you know 22 minutes can't get you the tick mark, you do the extra work required to create the space in your schedule.
With vision models, evidence-ing should be easy, but what's the best way to make it privacy first without needing a dedicate GPU tower at home?

This looks great!
I use Loop Habit Tracker¹ on Android which at a glance seems similar.
I wish someone could pair a habit tracker with a CalDAV task tracker like jtx Board².

This was posted on HN a while ago and I started using it then. I've accumulated quite a bit of data and have used both export and import. That's turned out to be the most useful feature for me
I've used other trackers, ones focused on CBT. My only suggestion is to allow text notes in each entry, so I can track emotional states or recurring thoughts

I don’t mind AI-written code. But an obviously generated README.md is such a turn off. If you don’t take the time to explain what your software does in your own words, I struggle to trust that it’s been thought about much at all.

Absolutely fantastic, for an age I've yearned for an iOS version of Loop Habit Tracker!
Great work.
