Install GitHub All Releases Packaging status

The latest official installers and portable versions for macOS, Windows, Linux and FreeBSD can be found at Github Releases page.


You can also install Stretchly with Homebrew by running brew update && brew install --cask stretchly. When upgrading, run brew update && brew upgrade --cask. Don't forget to Quit Stretchly, first.

Stretchly is not signed (due to its costs) so you will need to use this workaround for the first run: Open a Mac app from an unidentified developer.


You can also install Stretchly with Chocolatey by running the following command from the command line or from PowerShell: choco install stretchly. Upgrade with choco upgrade stretchly.

Stretchly is also available in Microsoft's winget.

You can install Stretchly for all users silently by running this as administrator: installer.exe /S /allusers.


For portable versions and for Linux/BSD installers, head to Github Releases page. The most widely used distributions should be covered.

Linux note

Please see for Electron's Tray Linux specifics. Having libappindicator1 installed should be enough for Stretchly.

For Natural breaks, you might need some packages too (libxss-dev).

If Stretchly is not starting, you might need to run sudo sysctl kernel.unprivileged_userns_clone=1. Read more here. Depending on your distro, you probably want to do something similar to this, so the settings are kept after reboot: Add kernel.unprivileged_userns_clone=1 to /etc/sysctl.d/00-local-userns.conf and reboot.

Running from source

To run Stretchly from source you will need Node.js, ideally the one specified in package.json. Clone the repo, run npm install and then simply run npm start to start Stretchly.

Custom installer

You can create a custom installer by running npm run pack or npm run dist after npm install --no-save.

Default behavior

When you run Stretchly for the first time, you are presented with a Welcome window that allows you to change the language, review the settings, view the online tutorial or simply continue with the default settings.

Stretchly itself lives in your tray, only displaying a reminder window from time to time, which contains an idea for a break.

By default, there is a 20 second Mini Break every 10 minutes and a 5 minute Long Break every 30 minutes (after 2 Mini Breaks).

You'll be notified 10 seconds before a Mini Break (and 30 seconds before a Long Break) so that you can prepare to pause your work.

When a break starts, you can postpone it once for 2 minutes (Mini Breaks) or 5 minutes (Long Breaks). Then, after a specific time interval passes, you can skip the break. Both actions are available by clicking on the link at the bottom of window or by using the Ctrl/Cmd + X keyboard shortcut.

Clicking the Stretchly icon in your tray area will display the current status of breaks, provide menu items with extra functionality, and link to the Preferences.

Stretchly is monitoring your idle time, so when you are idle for 5 minutes, breaks will be paused until you return.

Stretchly is also monitoring Do Not Disturb mode, so breaks are paused when DnD mode is On.

Stretchly follows the theme of your system and is also available in dark mode.

Interact with stretchly from command line

When a Stretchly instance is running, the stretchly command can be use to interact with it from the command line.

Type stretchly help to get a list of all commands and options available as well as some examples.


Most of the preferences can be customized by clicking on the "Preferences" item in the tray menu.

Preferences are divided into multiple categories and you are encouraged to take some time to make Stretchly your own by customizing them.

You can also Restore the defaults to return to the default preferences state.

Advanced Preferences

All preferences are saved in a JSON file. Use the Ctrl/Cmd + D shortcut while viewing the About section of Preferences, to show debug info and display a clickable link to the file.

It's recommended to Quit Stretchly before editing the preferences file.

To make sure that all works as expected, it's always good idea to check that format of the preferences file is correct, ie. by using jsonformatter.

Some of the extra settings are available in Contributor Preferences for Contributors. Those are marked by Contributor Preferences badge.

Note: Before 1.0, Mini Breaks and Long Breaks were called Microbreaks and Breaks, respectively. To keep the upgrade smooth they still use that name in preferences file and in code.

Editing Break ideas

In the preferences file, change useIdeasFromSettings: false, to useIdeasFromSettings: true, and edit breakIdeas and microbreakIdeas.

Note that when a new Stretchly version with new break ideas is out, your custom ideas will not be overwritten.

Editing Break notification interval Contributor Preferences

In the preferences file, change breakNotificationInterval: 30000, to whatever value you want. 30000 is 30 seconds. Same goes for Mini Breaks.

Editing sunrise time to pause breaks until morning

In the preferences file you can set the morningHour setting to pause until that hour today or the next day Otherwise, you can set morningHour: "sunrise" and set posLatitude, posLongitude in settings to pause until the actual sunrise in your area. E.g. if you live in Boston you would set: morningHour: "sunrise", posLatitude: 42.3, posLongitude: 71

Editing postpone functionality Contributor Preferences

In the preferences file, you can edit microbreakPostpone and breakPostpone to enable or disable the ability to postpone breaks, microbreakPostponeTime and breakPostponeTime to change the postpone time in milliseconds, microbreakPostponesLimit and breakPostponesLimit to change the number of allowed postpones per break, and finally, microbreakPostponableDurationPercent and breakPostponableDurationPercent to change the percentage of the break during which the user can postpone it.

New version notification Contributor Preferences

In the preferences file, set notifyNewVersion: false, to disable new version notification.

Play sound at the start of the Break Contributor Preferences

In the preferences file, set microbreakStartSoundPlaying: true, to start a Mini Break with a sound (The same sound will be played as at the end of the break). Same for breakStartSoundPlaying.

Natural breaks inactivity time Contributor Preferences

In the preferences file, set naturalBreaksInactivityResetTime to your preferred value (in milliseconds greater than than 20000ms). This is an idle time length, after which Stretchly breaks will be paused until the user resumes activity.

Volume for break sounds Contributor Preferences

In the preferences file, set volume to your preferred value. Default value is 1, which is 100% volume. Set it, for example, to 0.61 for 61% volume.

Postpone/Finish Break Shortcut

In the preferences file, set endBreakShortcut to your preferred value. We do not validate this input, so please check Electron's documentation for available values for key and modifier.

Appearance Contributor Preferences

In the preferences file, change themeSource: 'system' to either 'light' or 'dark' to always use the specified theme.

Welcome window Contributor Preferences

To show the Welcome window again on the next start, change "isFirstRun" to true.

Theme transparency Contributor Preferences

To specify how solid the break window should be when Theme transparency is enabled, set the value of opacity from 0 to 1 (which is in turn 0 to 100%).

Break window size Contributor Preferences

To specify the size of the break window, set the value of breakWindowHeight and breakWindowWidth from 0 to 0.99 (which is in turn 0 to 99% of the size of the screen). Don't set 100% as that's fullscreen.

Check for new version

If you don't want to ever check for new version, set checkNewVersion to false.
