Alongside the release of an updated WWDC app earlier today, Apple announced that developers attending the conference next week are invited to participate in an exclusive Activity challenge where they can earn a special reward.

Earn points each day, from Sunday, June 3 at 12:00 a.m. to Thursday, June 7 at 11:59 p.m., by wearing your Apple Watch and closing your Activity rings. Simply download the Challenges app on iPhone and allow Challenges to access Health app data, which includes data from your Activity rings. Work as a team of four with fellow WWDC18 attendees to earn as many points as you can. If everyone on your team closes their rings that day, you’ll get team bonus points (in addition to individual bonus points). Individuals who earn 200 points or more during the challenge will receive a reward on Friday, June 8 at McEnery Convention Center.

The Challenges app referenced has previously been used by Apple for internal employee fitness challenges, but this is the first time the company has utilized it with a broader group of participants.
