Apple Watch Ultra launched in 2022 as Apple's most rugged and capable watch. Its standout feature for sleep tracking is its battery life. Here are the best sleep apps for Apple Watch Ultra.

Why Apple Watch Ultra Is Great for Sleep Tracking
Apple Watch Ultra can last up to 60 hours on a single charge. This means you can wear it all day and all night for several days before needing to charge. The Ultra also includes the same sleep-relevant sensors as Series 8: SpO2, heart rate, wrist temperature, and crash detection. Its titanium case is comfortable enough for continuous wear.
