During WWDC, Apple will be launching a Close Your Rings Challenge that's designed to motivate developers to close the three Apple Watch activity rings each day of the week, with the challenge starting on Sunday, June 3 and lasting through Thursday, June 7.
To participate, developers will need to download the Challenges app from the App Store and sign up on the developer website for a unique invitation code. Move ring calorie goals will be set by weight for the challenge, and developers are able to team up with up to four friends to earn points.
If everyone on the team closes their rings each day, teams will be eligible for bonus points. All individuals who earn 200 points or more during the challenge will earn a reward on Friday, June 8, which will be given out at the McEnery Convention Center.
Participants will earn one point for each 1/12 of the Move ring that's completed (capped at 36 points), 1 point for each 1/12th of the Exercise ring that's completed (capped at 36 points), and 1 point for each 1/12th of the Stand ring (capped at 14 points) that's completed every day.
Individuals will earn 12 bonus points for closing all three rings on the same day, while teams will earn four bonus points for each teammate who closes all three rings that day.
Through the Challenges app on the iPhone, participants will be able to view a Challenge leaderboard and if in a team, team rank and status. Team members will be able to send motivating nudges to one another, and an Apple Watch complication is available for viewing daily point total.
Apple does not mention what the prizes are for winning the challenge, but for similar employee challenges in the past, Apple has given out unique pins, Apple Watch bands, and t-shirts.
The Close Your Rings WWDC challenge is limited to those who are attending WWDC, as the prizes will be given out in person at the end of the week. Attendees who want to participate can get an invitation code on Apple's developer site.
