How it works
Three steps. No sign-up.
Create a habit
Check, count or measure — scheduled daily, on chosen weekdays, or X times a week or month.
Tap to log
Your day grouped into morning, afternoon and night. One tap and you're done.
Watch it stick
Forgiving streaks, Habit Strength and real patterns from your own history.
Your day
Everything at a glance,
effortlessly.
A completion ring for the day, live streaks and your habits organized by morning, afternoon and night. Tap to complete — the rest updates itself.
- Progress rings, not cold checkboxes
- Every habit's streak always in view
- One-tap logging
Insights
See your patterns.
Week, 15 days, month, year or all time. A consistency heatmap, weekday bars and completion rates computed transparently from your real history — never guessed.
The science
Watch a routine go automatic.
Every habit shows its Strength, based on the Lally habit-formation curve. It's not a magic number — it's the math of your history, showing how close a routine is to becoming automatic.
Consistency (28d): 22 of 28 days
Privacy on your device.
This site does not receive your habit data. In the app, habits, history, and preferences are stored locally on your device. Kada uses no account or backend to store or sync that data.
Everything a habit needs.
Powerful where it matters, calm everywhere else.
Quantified habits
Check off, count (8 glasses of water) or measured goals (run 5 km, read 20 pages).
Flexible schedules
Every day, specific weekdays, or X times per week or month.
Forgiving streaks
A built-in grace day: one missed day doesn't erase weeks of progress.
Insights by period
Week, 15 days, month, year or all time. Consistency heatmap and weekday patterns.
Six languages
Portuguese, English, Spanish, German, Italian and French — complete and native.
Dark mode
Light and dark, calm by design. No ads, no noise.
No paywall
What others charge for is free here.
Many habit apps lock the essentials behind a subscription. In Kada everything is included — no premium tier, no trial that runs out.
There is an optional one-time tip that unlocks nothing. Never a subscription.
