| + | == 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 |

| + | 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. |
