OpenHabitTracker

Take notes, plan tasks, track habits

OpenHabitTracker is a free, open source habit tracker for Web, Windows, Linux, Android, iOS and macOS!

Why I created it

The friendly habit tracker

OpenHabitTracker doesn't use a streak counter as the main indicator
You won't feel demotivated when you skip a habit once, because a skip only raises the urgency
It tracks the time elapsed since you last completed a habit and compares it to the habit's repeating interval:
- A habit with a 10 day interval which is 2 days overdue is at 120%
- A habit with a 4 day interval which is 2 days overdue is at 150%
It allows you to easily prioritize your tasks based on their level of urgency

I built it as a personal project: the app has no ads, no trackers, no account, no subscriptions and no in-app purchases.

Habit tracker features

Take notes, manage tasks, track habits:

Notes in Markdown, rendered in the list, so reading one costs no clicks
Tasks with a planned date and time, a duration, a checklist and a timer
Habits with a repeat rule, a calendar and the full completion history
Categories that group all three, each with a rule for when the group counts as done
A priority on every note, task and habit

Search, filter and sort:

Control what the list shows with search, date, category, priority, status and sort
Planned dates and done dates filtered separately, each before, on, after or not on a date you pick
Date filters take a fixed date or a number of days from today, worked out when the query runs, so a saved filter never goes stale
Filter habits by how overdue they are, with a lower bound, an upper bound, or both
Turn the done-date filter around to see what you have not done in a period
Eleven sort keys, chosen separately for notes, tasks and habits
Search reads note text and checklist items, not only titles, and highlights every match where it sits
Show the category and priority filters as check boxes, radio buttons or a drop-down list

How search, filter and sort work in detail

Habit tracking:

Set how many times, how often, and whether that is per day, week, month or year
Measure a habit in repetitions, in time spent, or in a quantity you set a target for
Mark a habit done with a single click in the list, or fill in a day you missed
Each habit carries a timer, a checklist, a calendar and its whole history
Current and best streaks are there when you want them, counted in the habit's own period, so a weekly habit has a streak of weeks

Reminders and notifications:

A daily summary at a time you choose, naming the tasks that are due and the habits that are overdue
A reminder a set time before a task's planned time
Choose whether the summary covers tasks, habits or both, how overdue a habit has to be, and the lowest priority worth a notification
A day with nothing due sends nothing
On Android, iOS, macOS and Windows even when the app is closed, on Linux and in the web app while it is open

Statistics and charts:

Weekly statistics beside each list: habits on track, due soon and overdue, tasks done and overdue with the time spent, notes created and updated
Charts for every habit, whether it is counted in repetitions, time or quantity:
- Progress toward the target for today, this week, this month, this quarter and this year
- History by day, week, month, quarter or year
- A continuous calendar with no breaks between months
- The ten longest streaks
- How much gets done on each weekday, month by month

UI & UX

Appearance:

Dark and light mode, with 26 themes
Almost everything on screen can be turned on or off: which page and which sidebar open at start, what each row shows, which calendars appear, how the filters are drawn, and how tightly the lists are packed
Some of them add or remove whole blocks from a habit, so the same habit is either a short form or a full statistics page
A background color to tell your notes, tasks and habits apart at a glance
Your settings are saved, synced, and included in JSON and YAML backups

Everything you can turn on or off

Accessibility:

Everything reachable from the keyboard, with the calendar as an arrow-key grid
Every day cell announces its date and what was done on it to a screen reader
Focus moves into a sidebar when it opens and returns where it was when it closes
Animation is dropped entirely when your system asks for reduced motion

Available in 20 languages:

Chinese, Croatian, Czech, Danish, Dutch, English, Finnish, French, German, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Serbian, Slovak, Slovenian, Spanish and Swedish.
