Loop Habit Tracker - Habit tracker & progress

About the app

Loop assists you in forming and sustaining beneficial habits, enabling you to reach your long-term objectives. Comprehensive charts and statistics illustrate the evolution of your habits over time. The application is entirely free of advertisements, open-source, and prioritizes your privacy.

Elegant and contemporary design

Loop features a streamlined interface that is user-friendly and adheres to material design principles.

Habit strength

Besides displaying your current streak, Loop utilizes an intricate formula to assess the robustness of your habits. Each repetition enhances your habit, while each missed day diminishes its strength. However, a few missed days after a lengthy streak will not drastically undermine your overall progress, unlike many typical don’t-break-the-chain applications.

Comprehensive graphs and analytics

Visibly track how your habits have progressed over time with detailed graphs and statistics, allowing you to scroll back and review your complete habit history.

Adaptive scheduling

The app accommodates not only daily habits but also those with more intricate schedules, such as three times weekly, once every two weeks, or every other day.

Notifications

Set personalized reminders for every habit at specific times throughout the day. You can easily check, dismiss, or snooze your habit straight from the notification without launching the app.

Home screen widgets

Monitor your habits directly from your home screen using attractive and vibrant widgets.

Totally free of ads and open source

This app has no advertisements, bothersome notifications, or intrusive permissions. It guarantees this will remain true. The full source code is accessible under an open-source license (GPLv3).

Functions offline and safeguards your information

Loop operates without needing an internet connection or account registration. Your private habit data remains solely on your device. Neither the developers nor any outside parties can access it.

Export your data

If you wish to analyze your data further or transition it to another service, Loop enables you to export it to spreadsheets (CSV) or database formats (SQLite).

FAQs

How can I track bad habits I want to break?

Loop currently only supports tracking positive habits. Instead of tracking bad habits, an alternative is to rephrase your habit in a positive way. For example, instead of having the bad habit "Did you smoke today?" you could have the good habit "Did you have a smoke-free day today?". Another example, instead of "Did you eat junk food today?" you could have "Did you eat healthy today?".

How can I specify that a habit should be performed on certain days of the week?

You don't need to specify this. The app will figure it out by itself. You just need to specify how many times would you like to repeat the habit in a certain interval of time. For example, if you want to repeat a certain habit every Monday and Friday, simply specify that you want to repeat the habit 2 times per week, and then start practicing your habit. If, during your first week, you indeed perform your habit on Monday and Friday, the app will automatically add a checkmark on the following Saturday and Sunday. As long as you keep your routine, the checkmarks should appear automatically on the correct days.

When I am creating a new habit, what am I supposed to write on the "question" field?

The question field is a place where you can specify more clearly the requirements for the habit. For example, while the title of your habit might say "Meditate", the question might ask "Did you meditate for at least 10 minutes this morning?". This question appears on the reminders.

How can I put checkmarks in past days?

Open the statistics page for a certain habit, scroll down to the "Calendar" section and press the button "Edit" located under the calendar. Then, tap on the days to check or uncheck. You can also scroll sideways to change days further back in time.

How can I see the statistics page for a certain habit?

Just tap on the name of the habit.

How can I reorder the habits?

First, you need to select manual ordering by clicking the filter icon, then sort, then manually. Then, press-and-hold the name of a habit for a second. When it becomes selected, just drag it to the desired place, without lifting your finger.

How can I disable the vibration every time I put a checkmark?

Loop follows your phone's settings to decide whether it should vibrate on touch or not. To disable the vibration, open your phone's settings, tap "Sounds" and disable "Vibrate on touch".

What are unfilled checkmarks and why do they keep appearing?

Unfilled checkmarks are checkmarks that have been added automatically by the app, and not manually by the user. This happens with non-daily habits. For example, if you have a habit that should be repeated only one time every week, and you perform it on a certain Monday, the app will automatically add unfilled checkmarks on Tuesday, Wednesday an so on. To stop unfilled checkmarks from appearing, please change the frequency of the habit.

What do the dashes means?

Instead of a cross or a checkmark, you skip a day with a dash -. This means that the habit was skipped on this day: this leaves the score unchanged and doesn't break the streak. This can be useful in cases where there was no possibility to to fulfil the habit, e.g. if it requires to be in a certain location but you're away.

You can disable skip days in the settings.

How can I delete a habit?

On the main screen, press-and-hold the name of the habit for a second. When it becomes selected, tap the overflow icon on the menu bar (it looks like three vertical dots), then select delete.

How is the score calculated?

To compute the score of a habit, the app uses a statistical method known as exponential smoothing. Basically, it computes a weighted average that takes into consideration every repetition of the habit, from the very first day you started your habit until today. Recent repetitions, however, are considered more important than older ones, and have a larger impact on the score. This method has many nice features, including:

Every repetition counts, even way back in the past. This is not true for other simpler formulas, such as counting how many times have you performed the habit in the last week/month/year and then dividing by the number of days in that interval.

If you have a poor habit score, then a few repetitions can bring your score up very quickly. As your score improves, however, the reward for each repetition gets smaller and smaller, so you have to keep at it if you want to see further increases.

If you have a high score for a very long time and you take a short break, it's quite easy to restore your score back to what it was. If you start taking frequent breaks, however, then your score will suffer.

How long will it take to reach the highest score?

If you perform a daily habit perfectly, the score reaches 80% after one month, 96% after two months and 99% after three months. For non-daily habits, it takes longer to reach the same percentages. If your habit is repeated every other day, for example, then it takes two months to reach 80%, and if you habit is weekly, then it takes seven months.
