Kada: One Habit a Day

Kada helps you build habits that actually stick — with a calm, focused design and the science of habit formation built in. No account, no cloud, no noise.

PRIVATE BY ARCHITECTURE
Everything stays on your device. No account, no server, no tracking. Kada works 100% offline — your habits and your history simply never leave your phone.

HABITS, YOUR WAY
Track simple check-off habits, counters (8 glasses of water), or measured goals (run 5 km, read 20 pages). Schedule them daily, on specific weekdays, or X times per week or month.

STREAKS THAT FORGIVE
Keep your momentum with streaks — and a built-in grace day, so one missed day doesn't erase weeks of progress.

THE SCIENCE OF STICKING
Every habit shows its Strength, based on the Lally habit-formation curve: watch a routine become automatic over time. Consistency, completion rates and best streaks are all computed transparently from your real history — never guessed.

INSIGHTS THAT MEAN SOMETHING
See your progress by week, 15 days, month, year or all time. A consistency heatmap, a calendar you can drill into, weekday patterns and streak records help you understand when you thrive and when you slip.

CALM BY DESIGN
No ads, no manipulative badges, no endless notifications. Just a clear, beautiful view of the person you're becoming.

Kada. Your habits, on your device, for life.
