The average user abandons a habit-tracking app in 11 days."

30-day, 60-day challenges feel too long before you even start. So in Korea we have a saying: 작심삼일 (jak-sim-sam-il) your resolve lasts only 3 days. 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!"

After 3 days, take 1 day off, then start a fresh cycle. Short bursts, repeated wins.

• 3×3 bingo board for visual progress • One-tap stamp (5 seconds, then done) • Tiger mascot "Sammi" cheering you on • New card auto-issued each cycle • 12-week calendar of all your stamps • Full house = fireworks + tiger celebration • 100% free, no ads (v1.0) • 100% local data no servers, no tracking

Why 3-Day Habit?
