How is the streak calculated?

A streak counts the number of consecutive days you have checked off a habit ending today or yesterday. If you missed today but completed yesterday and the day before, your streak is still active until midnight.

Can I track habits over multiple weeks?

Yes. The tracker stores your full check-in history. The grid shows the last 7 days by default, and streaks and completion rates are calculated from your entire history.

How many habits can I track?

There is no hard limit. You can add as many habits as you like. For best results, most productivity experts suggest focusing on 3 to 7 key habits.

Why track habits?

Research consistently shows that tracking habits increases completion rates. The simple act of marking a habit done each day creates a visual streak you won't want to break — a concept popularized by Jerry Seinfeld's "don't break the chain" technique. Small consistent actions compound into lasting change over weeks and months.

Tips for building habits that stick

Start small

Make habits so easy you can't say no. "Meditate 1 minute" beats "Meditate 30 minutes" for consistency.

Stack habits

Attach a new habit to an existing one. "After I make coffee, I will write in my journal."

Protect your streak

A visible streak creates a commitment device. Missing twice in a row is the real danger — never miss twice.

Review weekly

Look at your completion rate each Sunday. Drop habits with under 40% completion — they're not sticking.
