If you have an Apple Watch, you can earn a special sticker on November 11 by playing at least 11 minutes. Last year, Apple organized a challenge during Thanksgiving, on November 24th. This year, the challenge seems to be shifting to another date: Veterans Day on November 11th. People with an Apple Watch can earn an extra badge and sticker on the day if they are going to play for at least 11 minutes. You can use the standard Workout app on the Apple Watch or third-party apps that exchange their workout data with HealthKit.

Veterans Day Challenge
"Do an 11min workout on November 11 to earn this achievement: I really like this one and rain or shine it'll be mine. Most other Vets will be earning this, I'm sure.
There will also be some iMessage stickers awarded but I'm not much for stickers. If they're Vet-centric that might change." visit article
