Gentle path
A miss does not break the path. DaoDaily helps you keep going, not start "from Monday" again.
Inside the app
What the tracker actually does
This list comes from the app code, not a marketing deck. Here is how DaoDaily keeps your rhythm day after day.
Flexible schedule
A habit does not have to be daily: set 1 to 7 times per week. The quota lives inside each calendar week and never carries debt over - a missed week does not turn the next one into punishment.
Smart goals: 7-90 days
Presets for 7, 21, 30, 66 and 90 days. 66 is the median for automaticity in the Lally study (UCL, 2010). Goals are measured in check-ins, not in perfect streaks.
Grace days: a miss does not reset the goal
Every 30 goal days add one spare day. 30 check-ins in 31 days still completes the goal. Science agrees: a single missed day barely affects habit formation.
Email reminders on your schedule
Pick weekdays, time and your timezone - we remind you only if the habit is not checked yet. No push notifications, no spam.
Pause and excused skips
On vacation or sick? Pause the habit or mark a skip as excused. Your stats stay honest and your streak stays alive.
Analytics: week, month, year
An activity heatmap, a six-period trend, a completed / missed balance and streaks - on a big screen where data is easy to read.
Insights into weak spots
The tracker shows which weekday you slip on most often and which habits are stalling. Not guesses - statistics from your own check-ins.
Milestone celebrations
25%, 50%, 75% and the finish line - confetti and a congratulation the moment you check in. Each milestone fires once: pleasant, never pushy.
11 languages
The app interface is available in Russian, English, Chinese, Spanish, Arabic, Portuguese, Indonesian, French, Japanese, German and Hindi.
Habit math
Calculate your goal
The widget below runs the same formulas as the app: check-ins required, spare grace days and celebration milestones.
Goal length
Median for automaticity in the Lally study (UCL)
Times per week
The formula from the app code: check-ins = (goal days / 7) x frequency; 1 grace day per 30 goal days. Based on Lally et al. (UCL, 2010): a habit takes 66 days on average.
