Apple Watch Ultra 4: buy one, get $300 off another @ T-Mobile
Buy an Apple Watch Ultra 4 at T-Mobile and you'll get $300 off a second one. The sale includes the Apple Watch 11 through the Apple Watch Ultra 4. New members will have to open two new wearable lines to get this offer. Our pick is the Apple Watch Ultra 4, whichnow supports continuous heart rate and heart rate variability tracking. It also features better battery performance (up to 50 hours per charge) and new health metrics like a daily Readiness Score and Health Age. In our Apple Watch Ultra 4 review we were fans of the Readiness score, which can show you at a glance when you're overtraining and need to rest.

The Apple Watch Ultra 4 is Apple's new premium watch. It now supports continuous heart rate and heart rate variability tracking and packs better battery performance (up to 50 hours per charge). There's also a handful of new health metrics like a daily Readiness Score and Health Age.

In our Apple Watch Ultra 4 review we tested the new heart rate sensor alongside a chest strap and an Oura Ring 5. In terms of readings, we found the Apple Watch Ultra 4 to be pretty much spot on. The new sensors also feed into the new daily Readiness score, which is only available on the Apple Watch Series 12 and Apple Watch Ultra 4.

It provides a single score with one of four different recommendations: Recover, Pace Yourself, Ready, or Go For It. Readiness updates throughout the day as new data comes in, and is based on your overnight vitals, sleep score, recent physical activity, and training load.

This deal is valid on the Apple Watch Ultra 4 or any other Apple Watch. It's one of the best deals I've seen on the new watches.
