build status:



Galileo is a Python utility to securely synchronize a Fitbit device with the Fitbit web service. It allows you to browse your data on their website, and compatible applications.

All Bluetooth-based trackers are supported. Those are:

  • Fitbit One

  • Fitbit Zip

  • Fitbit Flex

  • Fitbit Force

  • Fitbit Charge

  • Fitbit Charge HR

This utility is mainly targeted at Linux because Fitbit does not provide any Linux-compatible software, but as Python is cross-platform and the libraries used are available on a broad variety of platforms, it should not be too difficult to port it to other platforms.

Main features

  • Synchronize your fitbit tracker with the fitbit server using the provided dongle.

  • Securely communicate (using HTTPS) with the fitbit server.

  • Save all your dumps locally for possible later analyse.


The easy way

$ pip install galileo
$ galileo

Distribution packages

The following Linux distributions have packages available for installation:


The utility is available from AUR. You can install it using the yaourt package manager: yaourt -S galileo.


The utility is packaged in a COPR repo. Download the relevant repo for your version of Fedora, and then yum install galileo.


The utility is packaged as app-misc/galileo within the squeezebox overlay. See for details of how to use Gentoo overlays.


galileo is now officially part of the sid distribution.


The utility is available over the ppa ppa:cwayne18/fitbit. Use the following commands to install it and start the daemon:

sudo add-apt-repository ppa:cwayne18/fitbit
sudo apt-get update && sudo apt-get install galileo
start galileo

The more complicated way

First, you need to clone this repository locally, and install the required dependencies:


Need at least a 1.0 version, 0.4 and earlier are not compatible. Please use a tagged release as development version might contains bug or interface breakage.


Newer versions (2.x) preferred, although older should also work.

You should copy the file 99-fitbit.rules to the directory /etc/udev/rules.d in order to be able to run the utility as a non-root user.

Don’t forget to:

  • restart the udev service: sudo service udev restart

  • unplug and re-insert the dongle to activate the new rule.

Then simply run the run script located at the root of this repository.

If your system uses systemd then there is an example unit file in the contrib directory that you may wish to customize.


For the moment, this README (and the --help command line option) is the main documentation we have. The wiki is meant to gather technical information about the project like the communication protocol, or the format of the dump. Once this information reached a suffficient level of maturation, the goal is to integrate it into the project documentation. So head-on there, and start sharing your findings !

Manual pages for the galileo(1) utility and the galileorc(5) configuration file are provided within the doc directory.


Special thanks to the folks present @ the issue 46 of libfitbit.
