freehabittracker.app is a full-featured habit tracking tool that runs entirely in your browser. Create unlimited habits with custom names, colors, and frequency schedules — daily, weekdays only, weekends only, or pick specific days of the week. Each habit tracks a current streak and best-ever streak automatically. The Today view gives you a clean checklist of what needs doing, while the monthly calendar shows completion status for every day at a glance. A yearly heatmap — inspired by GitHub's contribution graph — visualizes your consistency across 365 days with color-coded intensity levels. The stats dashboard calculates current streak, best streak, monthly completion rate, and total check-ins in real time. Attach daily notes to any day to journal alongside your habits. When you need your data, export everything as a JSON file and import it on another device. Every feature works with zero sign-up, zero server calls, and zero cost.
Behavioral science shows that tracking habits creates a powerful visual feedback loop. When you mark a habit complete and watch your streak number climb, your brain gets a small dopamine reward that reinforces the behavior. This is the foundation of the "don't break the chain" method popularized by Jerry Seinfeld — the visual record of consecutive days creates social proof with yourself. Research from the British Journal of Health Psychology found that people who tracked their exercise were significantly more likely to maintain the habit than those who didn't. The key insight is that consistency matters far more than perfection. Missing one day doesn't erase your progress — the calendar and heatmap show that even imperfect weeks contain completed days. By making your effort visible, a habit tracker shifts the question from "should I do this today?" to "do I want to keep my streak alive?" That reframe makes the daily decision almost automatic.
Getting started takes less than thirty seconds. First, click the "+ New Habit" button in the sidebar and type a name — something like "Exercise," "Read 30 minutes," or "Meditate." Pick a color and choose how often you want to do it: daily, weekdays, weekends, or custom days. Second, come back each day and check off what you completed. The Today view shows your habits as large, tappable cards with a single-tap checkbox. You can also click any day on the calendar to mark habits retroactively. Third, watch your streaks, heatmap, and stats grow over time. The longer you track, the more motivating the data becomes. Your streak counter and completion percentage create natural accountability. If you miss a day, don't worry — just pick up where you left off. The heatmap will still show your overall consistency.
Most habit trackers require an account, store your personal data on their servers, and lock features behind a paywall. freehabittracker.app takes the opposite approach. There is no account to create — you open the page and start tracking immediately. All data lives in your browser's local storage, meaning nothing is ever uploaded to a server. The entire app loads as a single HTML file with zero external dependencies, so it works offline after the first visit. There are no ads, no tracking pixels, no analytics scripts, and no cookie banners. Every feature — unlimited habits, full heatmap, streak stats, daily notes, data export — is available free with no usage limits. The interface is intentionally minimal: a clean sidebar, a calendar grid, and a Today view that shows exactly what matters. For users who want more, an optional premium tier adds cloud sync across devices and advanced charts, but the core tracker is complete on its own.
Your habit data never leaves your device. freehabittracker.app stores everything in your browser's localStorage — a private storage area that only this website can access. There is no database, no server endpoint, and no API that receives your data. No cookies are set, no fingerprinting occurs, and no analytics or tracking scripts are loaded. The app does not know who you are, what habits you track, or how often you visit. If you clear your browser data, your habits are erased completely — because there is no backup on any server. For users who want a safety net, the Export button downloads a full JSON backup to your device that you control. The app is also a Progressive Web App, meaning it can be installed on your home screen and works fully offline with no network connection required. Your habits are your business, and freehabittracker.app keeps it that way.

Your streak resets but all your history is preserved. The calendar and heatmap still show every day you completed, so you can see your overall consistency. Habit science shows that bouncing back quickly matters more than never missing — just check off tomorrow and keep going.
