Habit Tracker

A Free Online Habit Tracker With Streaks

The Tools Kit’s free Habit Tracker is a simple daily habit tracker that runs in your browser. Add the habits you want to build, tick a checkbox for each day you complete them, and the tracker shows your current streak for every habit. There is no app to install and no account to create: your habits and check-ins are saved automatically in this browser’s local storage and never uploaded.

The grid shows a rolling week, today plus the six days before it, so it works as a weekly habit tracker and a streak tracker at the same time. It is deliberately minimal: think of a paper habit tracker chart, except the checkbox grid does the streak counting for you.

How to Use the Habit Tracker

1. 1

   Add a habit

   Type a habit name, such as "Drink water" or "Read 20 pages", and click Add habit or press Enter. Add as many habits as you like; each gets its own row.

2. 2

   Tick the days you completed it

   Click the checkbox under a date to mark the habit done that day. The grid shows today and the six days before it, so you can also log a day you forgot, as long as it is within that week.

3. 3

   Check your streak

   The Streak column counts consecutive ticked days backward from today. Tick today to keep the run going; the count stops at the first unticked day.

4. 4

   Come back tomorrow

   Everything saves automatically in this browser, so reopen the page on the same device and browser to keep logging. Use the trash icon to delete a habit you no longer want to track.

How the Streak Counter Works

A streak is the number of consecutive days, ending today, that a habit has been ticked. The tracker starts at today and steps backward one day at a time, adding one for every ticked day and stopping at the first day that is not ticked. Dates follow your device’s local calendar, so a new day begins at your local midnight, not at midnight UTC.

• Today, yesterday and the day before ticked, the day before that not ticked: streak 3.
• Yesterday and the five days before it ticked, today not ticked yet: streak 0 until you tick today, then 7.
• Ticked every day for 10 days in a row, the first three logged on earlier visits: streak 10, because the count continues past the visible week.

The streak looks back as far as 365 days, so a long run is counted correctly even though the grid only shows one week. Unticking any day inside the run shortens the streak to the days after that gap.

How Long Does It Take to Build a Habit?

The popular claim that a habit forms in 21 days is not backed by research. A 2010 study at University College London, led by Phillippa Lally, followed volunteers adopting a new daily eating, drinking or exercise behavior and found it took between 18 and 254 days for the behavior to feel automatic, with a median of about 66 days. How long it takes depends on the person and on how complex the habit is.

The same study found that missing a single day did not materially set people back. That is a useful way to read a streak: it is a motivation tool, not a scorecard. If yours resets, tick the next day and avoid missing twice in a row. Plan for around two months of consistent check-ins before judging whether a new habit has stuck.

Tips for Tracking Habits That Stick

• Make each habit specific. “Walk 20 minutes after lunch” is easier to tick honestly than “exercise more”.
• Start small. Track one to three habits first; add more once those are routine.
• Log on the same day. You can back-fill the last 7 days, but checking in daily keeps the streak honest.
• Stack habits. Attach a new habit to something you already do, such as reading right after dinner.
• Pair tracking with planning. Turn a bigger ambition into milestones with the Goal Planner, then track the daily action that moves it forward here.

Your Data Stays in Your Browser

The tracker has no server side. Your habit names and check-ins are written to your browser’s local storage after every change and read back when you return, which is why there is no login. The trade-off is that the data belongs to one browser on one device: it does not sync to your phone, it does not appear in a private window, and clearing your browser’s site data erases it. Deleting a habit with the trash icon also removes its history immediately, with no undo.

Common uses

• Building a daily habit such as drinking water, reading, meditating, or journaling
• Keeping an exercise or step-count routine going, alongside a target from the Calorie Calculator
• Tracking a daily study or practice session, timed in focused blocks with the Pomodoro Timer
• Seeing at a glance which of several habits you are keeping up and which are slipping
• Breaking a bad habit by ticking each day you avoid it, and counting the run since your last slip with the Days Calculator
• Keeping recurring daily routines separate from one-off tasks, which belong on the To-Do List
• Recording why a habit slipped or what helped, in a quick note with the Notes Organizer
