In this post, we are going deeper into the Dynamic Data project, looking at the Polar dynamic data (library available here on GitHub and at NPM). Opening the library, you’ll see there are twenty one types of data objects: getActivitySummary, getAvailableSamples, getAvailableSleepTimes, getExercise, getExerciseSummary, getHeartRateZones, getNightlyRecharge, getPhysicalInfo, getSamples, getSleep, getStepSample, getUserInfo, getWebhook, getZoneSample, listActivities, listExercises, listNightlyRecharge, listNotifications, listPhysicalInfo, listSleep, and listTrainingExercises.

About the data source
Polar (iOS|Android) is a fitness-tracking company offering various models of several fitness watches and sensors. The data traccked from these devices include:
Polar offers a free app, Polar Flow, on the app stores that analyze the data retrieved from their products. The main features offered by the app are Training and Activity tracking. Training tracking allows the user to create a workout reigment with set goals and targets and analyze their performnce of their training session. Activity tracking shows an overview of the data (calories burnt, heart rate, steps, etc) captured over any 24-hour period.
Polar has an API that grants access to the user's dataset. These requests generate JSON objects that are then stored in an NPM package. The index file of the package imports this data object and exports it in a collection called “Data”. These mockup files make up the polar-data package.
Models Generated With JSON Crack
The polar-mockups package imports the files above and goes through each attribute generating artificial (new) data using proprietary functions, such as those found in the utils package.
For example, with the getSamples object:

We welcome contributions and forks to this data set, and look forward to seeing what developers build in our Liberty. Equality. Data. Slack channel.
Considerations for next version/improvements
With Prifina developers can use the Dynamic Data Libraries natively in the App Studio to build direct to consumer apps where individuals can run them with their own user-held data.
Join our Slack community; Liberty. Equality. Data. to brainstorm and collaborate with other app developers, designers, and our team.
