All the Apple Watch Ultra Features Designed to Keep You Alive – Review Geek


The new Apple Watch Ultra is no ordinary smartwatch. It does everything the other Apple Watches can, but it’s also built to handle tough conditions and is perfect for outdoor adventurers.

While it probably won’t be able to handle extremely cold environments like Apple advertises, it’s still a rugged device with more life-saving features than you probably think.

Some of the features mentioned below are available on other Apple Watches we’ve all seen in commercials, while many are exclusive to the new Ultra. Either way, you’ll want to take advantage of them all. So here you have all the Apple Watch Ultra features designed to keep you alive.

Crash and fall detection

Apple car accident detection

For those who don’t know, Apple added a new car accident detection feature on all iPhone 14 models, Apple Watch Series 8, Apple Watch Ultra, and second-generation Apple Watch SE. For its watches, like the new Ultra, the company developed an improved 3-axis gyroscope and high g-force accelerometer sensor. These can detect forces of up to 256g that occur in a crash.

Thanks to an advanced “sensor fusion” algorithm built from years of lab testing and real-world results, your Apple Watch Ultra can accurately detect when you’re in an accident. When this happens, your phone can automatically alert emergency response teams if you don’t cancel the alert within 10 seconds. You’ll call 911, share your location, and even reach friends and family in your emergency contact list.

If you’re seriously hurt or injured and can’t call for help, this nifty feature could save your life. In addition, the company already had afall detection mode” which is still available, and both are great.

Emergency siren (SOS)


The Apple Watch Ultra has an improved speaker that can sound a loud emergency siren at almost 86 decibels, and it’s a great idea. Many hikers have whistles for emergencies, but you won’t need one with the Apple Watch Ultra. If you get injured on a trail, get lost, or can’t get out of a sticky situation, this siren could save your life.

There’s a big customizable orange “action button” on the side of the Apple Watch Ultra, and pressing and holding it will activate the siren.

Apple says its new emergency siren has two unique sound signatures with alternating patterns and can sound for several hours if needed. There’s a distress mode that’s loud and audible, while another mimics an SOS. Apple says someone can hear it over 600 feet away.

And while it doesn’t use the international alpine distress signal for hikers, it’s still a great feature we wish every Apple Watch had. This could also come in handy in daily life situations like mugging or robberies, making it pretty neat.

Compass Waypoints and Backtrack

For avid backpackers or outdoor enthusiasts, you’ll love the updated Compass app in WatchOS 9. While it now presents more detailed views and information on a single screen, you’ll love the Waypoints and Backtrack features.

For one thing, you can now quickly access the Compass Waypoint feature and drop a marker showing your location. You can add more as you go, showing the direction and distance from the previous point. These location points could even help emergency services find a lost hiker.

Additionally, by using GPS data from the Ultra, owners can use the new Backtrack feature. This creates a chronological route of all waypoints as you hike, camp, travel, or go offline. It also happens automatically in the background. If you get lost or need to retrace your steps to get back to camp or civilization, this will give you step-by-step instructions to get you home safely.

Dual GPS to improve location accuracy

Accurate location information is undoubtedly important, but it is crucial in an emergency. Whether you’re using the aforementioned backtracking feature, hiking a mountain ridge, or need enhanced location data, the Apple Watch Ultra has you covered thanks to an all-new dual GPS setup.

Apple added dual frequency GPS which is better than any Apple Watch so far. It uses GPS L1 and L5 frequencies and improved positioning algorithms to deliver the most accurate GPS signal of any smartwatch on the market.

As you can probably imagine, this is useful for various situations, from adventures to emergencies.

cellular connectivity

The regular Apple Watch comes in either a standard Wi-Fi model or one with Wi-Fi + Cellular connectivity. The cellular version basically puts the same connectivity as your phone right inside your wrist to make calls, send a text, or view Apple Maps. If you only have the Wi-Fi model, you can’t do those things unless it’s paired with your phone.

Every Apple Watch Ultra comes with cellular connectivity, which means it will work without being connected to a phone. You can go for a run and still make phone calls or send a text message, follow routes on the map during a bike ride, and much more.

If you get stuck in an emergency and can’t reach your phone, lose it, or the battery dies, you could theoretically use the Apple Watch Ultra to get out safely. Use the Ultra to call for help, text a family member, view Reverse Mode, or follow a map to stay safe, even when your phone isn’t available.

Remember that you will need to pay for an additional line of cellular service from your carrier for this functionality to work.

Depth and water temperature sensors

The new Apple Watch Ultra is also perfect for water sports or diving. The Ultra can handle depths and temperatures that the regular Apple Watch can’t. It is rated to 100 meters under ISO 22810, and is even certified for recreational diving (EN 13319), which is pretty good.

When you dive, a new depth app will automatically open that can display the time, current depths (up to 40 meters), water temperature, and various other stats. It’s basically an underwater computer.

And while this is more of a novelty feature than anything else, displaying this automatically instead of a diver having to navigate to this critical information could be useful in certain situations.

Apple claims that the watch can survive in temperatures ranging from negative four degrees to 131 degrees Fahrenheit. So whether you’re diving deep cold water or climbing a mountain on a hot summer day, the Ultra is ready for the job.

SOS emergency call

Similar to Apple’s new emergency siren on the Watch Ultra, all Apple Watches have a SOS emergency mode that is readily available and could potentially save a life. This isn’t unique to the new Ultra, but it’s worth mentioning.

Press and hold the button under the digital crown (how you turn off the watch) and you’ll find the Emergency SOS option. Drag the SOS slider from left to right and you’ll instantly make a call, alert your emergency contacts, share location data (if allowed), and more.

Or, if you can’t look at and interact with your watch, press and hold the button nonstop, and after 20 seconds, it will automatically call emergency services.

Medical ID

While it’s nothing new, Apple Medical ID Section There is a hidden gem in the health app on phones and watches that everyone should take advantage of. In the event of an emergency, when your watch detects a fall or crash, as explained above, or you send an SOS signal, Medical ID can share important information about your health with first responders.

This information includes your blood type, medical history, medical notes, conditions, allergies, and more. You’ll need to open the Health app on your phone, fill out all the medical ID cards, and then sync it to your Apple Watch Ultra. From there, you can customize when that information is displayed, and it’ll even preset Medical ID stats on your watch’s lock screen in a true emergency.

It might sound like a minor feature not worth completing, but depending on the situation, it could save your life.

ECG and cardiac monitoring

Apple Watch Ultra ECG (ECG)

And finally, we wanted to mention Apple’s continued efforts in health with its ECG and heart monitoring capabilities on the watch. Again, this isn’t new or unique to the Apple Watch Ultra, but it can keep you alive if it detects an irregular heartbeat or other issues.

The ECG app on your Apple Watch can take an electrocardiogram (ECG or EKG), similar to what you would find in a doctor’s office. The ECG app can record your heartbeat and rhythm, then check for atrial fibrillation (AFib) or a high or low heart rate.

Remember that Apple’s ECG app can’t detect heart attacks, but it’s still one aspect of the watch that can have big consequences. You can even share the results instantly with your GP, which is great. These watches even have a blood oxygen sensor to track health, fitness and wellness.

According to Jeff Williams, Apple’s chief operating officer, the company specifically designed the Ultra for “exploration, adventure, and endurance.” Then Apple carefully created useful features that can take advantage of design, durability, and technology.

When you combine all of that, it’s a capable watch that could keep you alive. Most people will use the Apple Watch Ultra for regular activities, but for outdoor enthusiasts, it has a host of benefits that you can use and appreciate.
