Chrono is a time tracking tool written in Go. It is fast and simple to use.

Want to know what you did with your time? Chrono will help you with that. Track how long you spend on a project. Add notes so you know exactly what you did.



Binaries Releases

To install the latest stable release:

curl -L | sh

We provide pre-built Chrono binaries for Windows, Linux, and macOS (Darwin) for x64 and i386 architectures.

If you'd like to install a specific version, checkout the releases page.

If you want to run the absolute latest version, build it from source.

Package Managers

If you are using Arch Linux, you can install the AUR package chrono-git to get the latest version or chrono for the latest stable release.

If you're using Ubuntu or a Debian based system, you can find debian packages (.deb) on the releases page.



To start tracking time a project, use the start command:

$ chrono start development +chrono

If you wanted to set the start time to something other than now, use the '--start' flag:

$ chrono start development --at "2019-02-01 13:00"

Time is parsed by jinzhu/now so it should be in a format it can understand.

This creates a new frame for the development project with the chrono tag.

Keep notes of what you do for a project with the notes add command:

$ chrono notes add "made some awesome changes to the README"
$ chrono notes show
[0]: made some awesome changes to the README

The notes are added to the current frame.

Get information about the current frame with the status command:

$ chrono status
Project development [chrono] started 10 seconds ago.

To stop tracking time for the current frame, use the stop command:

$ chrono stop
Stopping project development [chrono], started 5 minutes ago (id: 073bbf).

You can show a chronolical list of the current day's session (or frames) through the log command:

$ chrono log
Monday  3 December 2018
    (ID: 0d3131) 10:15 to 10:20     0h 05m 00s  development [chrono]

For a list of all available commands, use the help command:

$ chrono help

For a list of all available options and arguments for a command, use the ---help flag:

$ chrono log --help

Building Chrono from the Source

Prequisite Tools

Downloading & building the source

Chrono uses Go Modules to handle dependencies.

The easiest way to build from the source is to clone Chrono in a directory outsite of GOPATH, for example:

mkdir ~/src && cd ~/src
git clone
cd chrono
go install

Make sure $GOPATH/bin is on $PATH.

If you haven't customized your $GOPATH then you'll need to add ~/go/bin to $PATH.
