About Kadō — Habit Tracker
Kadō is a mindful habit tracker that gives you a clear, honest picture of how you're building your routines — without the all-or-nothing guilt of a streak counter. ---------------------------- A HABIT SCORE, NOT JUST A STREAK ---------------------------- Kadō's core algorithm rewards long-term consistency. One missed day doesn't wipe your progress. A strong stretch matters more than a perfect one. You see the trend, not a fragile chain. ---------------------------- PRIVATE BY DESIGN ---------------------------- • No account required • No analytics, no telemetry, no advertising SDKs • No third-party services — only Apple frameworks • Your data lives on your device • Optional sync through your own iCloud (never on our servers) ---------------------------- NATIVE TO APPLE ---------------------------- • Universal app — iPhone and iPad • Home Screen widgets in three sizes • Lock Screen widgets (rectangular, circular, inline) • Siri and Shortcuts support • Rich monthly calendar with history • Full Dark Mode and Dynamic Type support • VoiceOver labels on every surface ---------------------------- YOURS TO KEEP ---------------------------- • CSV and JSON export in one tap • Import from Kadō backups (round-trip tested) • Source code on GitHub under the MIT license • No subscription, ever — optional Tip Jar if you want to support development ---------------------------- FLEXIBLE SCHEDULES ---------------------------- • Daily habits • N days per week (e.g. 4 times a week) • Specific weekdays (e.g. Mon / Wed / Fri) • Every N days (e.g. every 3 days) • Binary, counter, or timer habit types ---------------------------- BUILT IN THE OPEN ---------------------------- Kadō is built in public.

Version 1.14 · Updated October 13, 2026
Version 1.14 — Side by side. • On iPad, Today now shows your habits and the one you pick next to each other. Tap a habit to see its score, streak and calendar beside the list — and keep logging from the list without leaving it. • The same layout on iPhone Duo when it's unfolded. Folded, Kadō works as it does on any iPhone.
