- Apple’s most-touted new watch feature is the blood-oxygen sensor and its accompanying app. To use the feature, ensure the Watch is snug on your wrist and don’t move while taking the reading. As long as you meet those requirements, it only takes 15 seconds to return the reading.
- The reading shows the percentage of oxygen present in the bloodstream. It obtains this by detecting the color of the user’s blood using red and infrared lights. The returned value does not give much information on its own, as it does not explain if a reading is “good” or not.
- Apple’s vagueness about the value is likely due to its skirting of the medical device requirements. Apple says that the blood oxygen measurement is only for wellness and fitness purposes and not intended to replace a medical device, such as a pulse oximeter, which requires federal approval.
Apple included all the other sensors introduced in previous generations of Apple Watch in the Apple Watch Series 6. It has a heart rate sensor that continuously monitors the user’s heart rate every few minutes, depending on activity. If you are engaged in a workout, your heart rate will be continuously monitored until three minutes after the workout.
If it detects abnormal heart rates, it will notify the user. The Apple Watch cannot detect a heart attack, but it can warn users before a fatal heart event if their heartbeat becomes too fast, slow, or irregular.
Users can also perform an ECG using the latest Apple Watch models. Introduced with the Apple Watch Series 4, you can take an ECG using the built-in app. The Watch must be worn tightly during the measurement. The measurement is performed by placing a finger on the Digital Crown for a minute. The ECG app guides you through the process.
Launched during the “Time Flies” event, Apple Fitness+ allows customers equipped with an Apple Watch and another Apple device with a screen to perform guided workouts. Displaying a workout on an iPhone, iPad, or Apple TV, the app will monitor the user’s workout via Apple Watch sensors.
Apple’s trainers provide a series of weekly studio workout videos. They cover various workout types, including high-intensity interval training (HIIT), yoga, and strength training. Apple Watch data appears on the screen as an overlay, letting users keep track of their progress without looking at the Watch. This includes notifications for reaching fitness goals on their rings.
The new flagship wearable is Apple’s first to include the U1 Ultra Wideband chip, according to technical specifications listed on the company’s website. Apple’s UWB solution debuted with iPhone 11 in 2019.
It’s unclear what features the U1 will add for Apple Watch owners. Currently, the chip serves as a backbone for directional AirDrop functionality on iPhone 11 and later handsets and will serve as a part of the CarKey system in upcoming vehicle models.
Family Setup lets you set up your children’s Apple Watches without needing their own iPhone. Children in the household get a phone number for each Apple Watch, allowing the family to keep in touch even if the kids don’t have phones.
Family Setup lets parents specify with which contacts children can communicate. It can also send parents automatic location notifications to keep tabs on where their family is. Kids can use their Apple Watch to track their movement and all Apple Watch activity features.
Apple introduced a new band that loops around without connectors or clasps. It is a simple elastic band that needs to be sized to fit.
Orders placed with the new band type require users to measure their wrist size using a paper print-out, which has led to some errors. Some users guessed their size without performing the measuring task. To receive a replacement, those who received incorrectly sized bands had to return their entire packaging, including the Apple Watch itself.
New with the Series 6 is an integrated blood oxygen sensor. It works similarly to the ECG sensor. It shines a myriad of lights onto the back of your wrist, and a sensor measures the light that is reflected to determine the oxygenation of your blood.
Despite reported issues with getting a blood oxygen reading, we had no such problems. There may be variability based on band tightness, skin color, and other factors.
