This gem provides access to fitbit.com data through their REST API. Fitgem can pull data with or without a valid OAUth access_token. Without an access_token you can only gather data that a user has denoted as 'public'. However, if an access_token is provided then all exposed data can be gathered for the logged-in account.
The Fitbit API is currently in BETA and is under development to extend its reach. As the API evolves and is enhanced it's a priority to mirror the functionality in the gem, and pull requests are appreciated if you see gaps in API support.
Install fitgem
$ gem install fitgemor add it to your Gemfile
gem 'fitgem'Comprehensive method documentation is available online.
The best way to connect your users to the Fitbit API is to use
omniauth-fitbit to integrate Fitbit accounts into your web application. Once you have a Fitbit API OAuth access_token for a user it's simple to create a client object through fitgem to send and receive fitness data.
The Fitbit API allows for you to set up notification subscriptions. When user data changes (through syncing with the fitbit device) your applications can be notified automatically. You can set up a default subscription callback URL via the Fitbit dev site and then use the Subscriptions API to add or remove subscriptions for individual users.

The reference app is written using Rails 3.2 and Backbone.js and includes examples on how to:
- Integrate OAuth logins omniauth-fitbit
- Store and use OAuth access tokens
- Create and use instances of
Fitgem::Clientusing the stored OAuth access token
The Fitbit REST API is in BETA right now, and so it will quite likely change over time. I aim to keep as up-to-date as I can but if you absolutely need functionality that isn't included here, feel free to fork and implement it, then send me a pull request.
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
- Fork the project
- Start a feature/bugfix branch
- Commit and push until you are happy with your contribution
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
Many, many thanks to everyone that has contributed to improve fitgem!
