3-Day Habit

The average user abandons a habit-tracking app in 11 days." 30-day, 60-day challenges feel too long before you even start.

It's actually a useful insight: 3 days is the threshold. 3 Habits × 3 Days = 9-cell bingo 3-Day Habit is the smallest habit tracker. • Pick 3 habits to challenge (e.g., 2L of water, exercise, reading) • Stamp one cell each day for 3 days • Fill a row → "Three-day curse beat!"
