Most habit trackers celebrate your 30-day streak with a fire emoji — then reset you to zero when you miss one day. That cycle of guilt is why 80% of people quit within two weeks. NudgeBit replaces streaks with momentum: miss a day and your score dips from 86% to 71%. Not to zero. Never to zero.
- Momentum, Not Streaks — rolling 7-day window, not binary pass/fail
- Rest Days Are a Feature — tap Rest and your momentum stays the same
- Habit Formation Score — science-based 66-day tracker, from seed to rooted
- Start With One Habit — grow to three only when momentum stays above 70%
- Momentum Ring — shifts from lavender to gold as you build consistency
- 28-Day Heatmap — green for done, blue for rest, gray for missed. No red. Ever
- Gentle Phrases — "Every step matters" at 30%, "This is who you are now" at 90%
