Fitbit is an a manufacturer of wearable devices and provider of fitness/wellness related services. Since 2009 they have released a large variety of different activity trackers and smart watches with different form factors and sensors, as well as a range of smart scales. In 2019, Fitbit introduced a subscription model called [https://investor.fitbit.com/press-releases/press-release-details/2019/Fitbit-Launches-Fitbit-Premium-New-Health-and-Fitness-Subscription-Service/default.aspx ''Fitbit Premium'' for which the company charges ~10 USD/month for access to particular metrics], such as advanced body temperature details or stress. 

== Data collected by Fitbits ==
Given the large variety of different models and series of Fitbit devices (see table below), details between models change. But virtually all recent Fitbit devices record at least the following: 

* [[Activity tracking]] 
** Steps taken
** Floors climbed
** Heart rate metrics (Heart rate throughout day, resting heart rate, [[HRV (Heart Rate Variability)|heart rate variability]], recording of workouts)
* [[Sleep tracking]] 
** Time slept
** Sleep phases throughout the night

Additionally, more recent Fitbits also record additional metrics, such as 

* [[Skin Temperature]]
* [[ECG]]
* Stress tracking

== Exporting Fitbit data ==
Fitbit allows the export of up to 31 days of data – aggregated into daily statistics – [https://www.fitbit.com/settings/data/export through their website]. Additionally, Fitbit provides an API that allows users to authorize third parties to export their own data. This integration does not have a limit for how much historic data can be exported. By default this API is also limited to daily aggregate values, but a ''personal API'' is available, which does provide access to intra-day resolution data.

=== Data export through Fitbit API ===
The [https://dev.fitbit.com/apps Fitbit web API] allows you to register your own ''app'', which means that you can create the necessary authentications to access your full data through third-party tools or your own scripts. For some programming languages, such as Python and R, there are ready-made libraries that one can use to access data from Fitbit. 

====Exporting with a Python library====

The [https://github.com/orcasgit/python-fitbit ''python-fitbit'' library] provides access to most data that your Fitbit collects. A recent [https://towardsdatascience.com/using-the-fitbit-web-api-with-python-f29f119621ea guide on how to set it up can be found on Towards Data Science].

==== Exporting with an R library ====
[https://github.com/teramonagi/fitbitr ''Fitbitr'' is a library for the R] programming language that provides the same functionality as the Python modules outlined above. The README of the package [https://github.com/teramonagi/fitbitr/blob/master/README.md gives a good getting-started guide].

==== Exporting through Open Humans ====
[[Open Humans]] provides two different integrations that enable the export of all historic Fitbit data into a user's private storage with low effort. The regular [https://fitbit.openhumans.org/ Fitbit API integration] does not require any complicated setup on the user end, but is limited to daily aggregate data. The more detailed [https://fitbit-intraday.openhumans.org/ Fitbit Intraday Connection] requires setting up a ''personal Fitbit API app'', but requires no coding of data export functions after this setup. 

== Personal Science projects that used Fitbits ==
This is to be considered a living and non-exhaustive list:

* [[User:Gedankenstuecke|Bastian Greshake Tzovaras]] used Fitbit trackers and scales to explore
** [https://tzovar.as/phd-survival-guide/ how the final writing period for his PhD thesis changed his physical activity and weight]
** [https://tzovar.as/on-getting-sleep/ how sleeping alone vs. sleeping with someone else in the same bed effects his sleep patterns]
* Jakob Eg Larsen [https://quantifiedself.com/show-and-tell/?project=1082 compared sleep and heart rate data from two Fitbit devices, an Oura Ring, and a Basis Smartwatch]

==Overview of fitness tracker / smartwatches ==

The table below [[wikipedia:List_of_Fitbit_products|is taken from Wikipedia]]. It does not include the smart scales.
