Apple celebrated Earth Day by awarding special badges and stickers to certain Apple Watch users6
This continues a trend that saw Apple offer special achievement badges to Apple Watch users during Thanksgiving. Keep in mind that it is always good to exercise away all of that turkey consumed on that holiday. And Apple also offered a "Ring in the New Year Challenge" in January.
You might have seen Apple's new ad for the Apple iPhone 7 and Apple iPhone 7 Plus that focused on how users can now slap stickers on iMessage. Stickers also figured prominently in the Apple Watch's Earth Day celebration. Those who did manage to keep moving for 30-minutes or more not only were awarded the aforementioned badges, but also gained access to special stickers that could be employed on messages sent via iMessage.
