Apple watch sport features include unique Apple workouts like yoga, cycling, swimming and high-intensity interval training. Activity rings are just one of the Apple watch fitness features to keep you motivated, and you can share your Activity with friends or ask them to compete in a seven-day Activity challenge. The temperature sensing feature is not a medical device and not intended for use in medical diagnosis, treatment or for any other medicalpurpose. You don't need the Series 6 to take advantage of these features. WatchOS 7 is also available on Apple's Series 3, 4, and 5 watches, as well as the new Watch SE. Apple Watch SE has a water resistance rating of 50 metres under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch SE should not be used for scuba diving, waterskiing or other activities involving high-velocity water or submersion below shallow depth. Water resistance is not a permanent condition and can diminish overtime. For additional information, see support.apple.com/en-gb/HT205000. Perhaps the watch's biggest strength remains the App Store, which lets you browse and install apps right on the watch itself. With more than 20,000 Apple Watch apps available, it easily has the largest, highest-quality third-party selection of any wearable.

ECG app is available on Apple Watch Series 4 and later (excluding Apple Watch SE) and can generate an ECG similar to a single-lead electrocardiogram. Intended for use by people 22 years old and over.

Apple Watch Series 6 has everything you want in a smartwatch, all wrapped up in a case that’s 11% thinner than the Apple Watch Series 3. Compared to previous generation Apple watches, it has a 30% larger Retina display. The Series 6 also features a new antenna with double the spectrum of the Series 5 that enables it to support 5GHz Wi-Fi for the first time. This can help free up congested 2.4GHz bands, while allowing access to potentially speedier 5GHz bands.

The Samsung Galaxy Watch3 offered similar battery life in testing, but the Fitbit Sense lasted around three days.Features are subject to change. Some features, applications and services may not be available in all regions or all languages. View complete list. Apple Watch Ultra 2 has a water resistance rating of 100 metres under ISO standard 22810. It may be used for recreational scuba diving (with compatible third-party app from the App Store) to 40 metres and high-speed water sports. Apple Watch Ultra 2 should not be used for diving below 40 metres. Water resistance is not a permanent condition and can diminish over time.

The standout feature here is a new sensor that can measure the oxygen saturation of your blood, also known as SpO2. This metric indicates how well your circulatory and respiratory systems are delivering oxygenated blood to your body. Your SpO2 reading alone can't diagnose COVID-19, but as the Yale School of Medicine advises, a reading below 90 percent may warrant a trip to the emergency room.In the box with the watch, Apple includes a charging cable, but you don't get a USB power adapter. Apple says it made this decision to help the environment, and it will have the same impact as eliminating 50,000 cars from the roads. Design Case and strap combinations can be made within collections (AppleWatch, AppleWatchNike and AppleWatchHermès) only. The assurance that the unit meets Apple's premiere quality standards, and that its defective components have been replaced by genuine Apple components Irregular rhythm notification requires the latest version of watchOS and iOS. It is not intended for use by people under 22 years old or those who have been previously diagnosed with atrial fibrillation (AF).

The Series 6 is light and comfortable on my wrist, even when I wear it to bed. The 40mm and 44mm aluminum models weigh 1.07 ounces and 1.28 ounces, respectively, without the strap. The stainless steel models are the heaviest at 1.40 ounces and 1.66 ounces, and the titanium models weigh 1.22 ounces and 1.45 ounces. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2023 using pre-production Apple Watch Series 9 (GPS) and Apple Watch Series 9 (GPS + Cellular), each paired with an iPhone; all devices tested with pre-release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary. When you start a blood oxygen scan, you'll see a 15-second countdown timer on the screen along with a relaxing blue and red graphic. After 15 seconds, your blood oxygen saturation percentage will appear onscreen. You can also view blood oxygen measurements in the Health app on your iPhone. The watch offers information about this metric to help you interpret your data. It says that most people have a blood oxygen level between 95 and 100 percent. The first time I used this feature, the Series 6 said my blood oxygen saturation level was 99 percent. The second time I took a reading, it was after a three-mile beach run, and I was happy to see my SpO2 level was 100 percent.Apple's new smartwatch focuses on health. One of Series 6's most talked about features is the new pulse oximeter, or blood oxygen meter. Thanks to a built-in Sp02 sensor, it is capable of analysing O2 concentration in just 15 seconds. And that's not all. It can even perform electrocardiograms via the ECG app. Simply rest your finger on the Digital Crown. If any signs of anomalies, such as irregular arrhythmias, are detected, the app alerts the user, providing comprehensive data. In addition, the watch monitors sleep (helping you to create routines for more restful nights), keeps tabs on your physical activity and suggests training sessions, features an altimeter that measures in real-time, and is waterproof up to 50 m. It even reminds you to wash your hands regularly! Different Models, Different Prices The international emergency calling feature requires an Apple Watch Series 6 (GPS + Cellular) model.
