DALI is partnering with Dartmouth’s Psychological & Brain Sciences Department to create an app that tracks participants' exercise and prompts them to take memory games in order to determine whether there is a positive correlation between exercise and memory. This application uses the HealthKit API to whether a user has performed a workout. If yes, then a user waits an hour before he or she is prompted to play a game. The user alternates between workout day and lazy day (the user just plays game without having to work out).
