Habit tracker features
A calendar, smart goals and analytics - everything you need to make a habit automatic. No install, no subscriptions.
A web habit tracker: works in the browser on desktop, tablet and phone. Free.
01 - Foundation
Three tools, one rhythm
Analytics
Streaks, 6-month charts, and completion balance on a big screen where data is easy to read.
Path, not race
Dao philosophy: small steps every day beat rare sprints. No pressure, no overload.
02 - 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.
03 - 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.
