Version 0.1

This version concentrates on producing the features of the app that are central to its purpose.

#	Title	User Story	Notes
1	Workouts	As a user, I can perform a workout	The user can choose a workout (sequence of exercises) to perform and will be guided through it. Timers, prompts and videos are used to guide the user through. Their workout activity is stored in Core Data. A selection of workouts are available to choose from.
2	Calorie burn data	As a user, I am able to see how many calories I burned during and after a workout	At the end of a workout, the user's heart rate and perceived level of exertion are measured. These data points are used to calculate their calorie burn during and after the workout. A graph on the main screen shows the user their activity over the last 7 days - their calorie burn from each workout and their 'excess calorie burn' each hour.
3	Exercise library	As a user, I can see videos and information on 50+ exercises	All exercises are available in a 'library' that is separate from the workouts. The user is able to view information on each exercise and watch its associated video.
4	On-demand video downloads	As a user, I can download exercise videos only when I need them	There are 50+ exercise videos so we we will only include a few of them in the app bundle. Videos are downloaded when the user needs them for a workout or when requesting one in the library.
