Fitgem

Provides access to fitbit.com data through their REST API. Fitgem can pull data with or without user authentication. Without user authentication, any data that the a fitbit.com user has denoted as 'public' can be gathered. If a user logs in via OAuth then all exposed data can be gathered.

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 any pull requests are appreciated if you see gaps in API support.

Usage

Install fitgem

$ gem install fitgem

or 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.

Reference Application

To learn more about how to use fitgem in a Rails application, go to http://fitbitclient.com or see the code at https://github.com/whazzmaster/fitgem-client.

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::Client using the stored OAuth access token

Subscriptions

The Fitbit API allows for you to set up notification subscription so that when values change (via automatic syncs 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.

Help Improve Fitgem!

The Fitbit REST API is in BETA right now, and so it will quite likely change over time (though I can't be sure whether it will be additive change or change of the non-backwards-compatible variety). 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!
