The Apple Watch Series 12 may bring users back to the Apple Watch after years of relying on WHOOP, especially with the improvements Apple has made to health tracking and data display. This shift isn't limited to the watch itself; the experience also benefits from the significant update to the Apple Health app with iOS 27.

Apple has noticeably improved the Health app's design, presenting data and statistics in a more organized and easier-to-read way, making understanding daily health information much simpler.

Data display wasn't the only issue with previous Apple Watch models; the watch collected heart rate data much less frequently than WHOOP. The Apple Watch Series 12 now measures heart rate every 5 seconds, compared to every 5 minutes in previous models.
