Why Track Your Habit Streaks?

Habit streaks are a powerful motivational tool backed by behavioral science. When you see a visual chain of completed days, you are less likely to break it. This is known as the “Seinfeld Strategy” - comedian Jerry Seinfeld famously used a wall calendar to track his writing streak, and the simple act of not wanting to break the chain kept him consistent.

The Power of Consistency Over Perfection

Your consistency percentage matters more than a perfect streak. Missing a day does not erase your progress. Research shows that what matters most is getting back on track quickly. The goal is never missing twice in a row, not achieving perfection.

Stop counting by hand

Let the chain count itself

You just typed those days in from memory. Tick the habit off instead and the streak, the consistency percentage and the calendar keep themselves — including the part where you miss a Tuesday and pick it straight back up.
