Apple and Aetna created an app to track and reward members' healthy behavior, CNBC reports.
What you should know:
1. The companies have been collaborating to build the Attain app since 2016. Members can sign up to track their progress using the Apple Watch or iPhone beginning this spring.
2. Participating members will receive personalized health goals, recommendations, reminders and rewards. They will be nudged to engage in healthy behaviors such as getting their annual flu shot or taking their medication on time.
3. For members who don't already own an Apple Watch, rewards include earning back the cost of the device by meeting fitness goals.
4. Members' data will be encrypted, and Apple said it won't access unique personal data.
5. Aetna will initially allow between 250,000 and 300,000 members to sign up on a first-come, first-serve basis. It eventually hopes to extend access to its 22.1 million members.
6. In early January, Apple CEO Tim Cook told CNBC he believes the company's "greatest contribution to mankind" will be related to health.
7. This is a growing trend in the insurance industry. John Hancock introduced a similar program, Vitality, in 2015.
