Like a baby learning how to walk and talk, the Apple Watch can finally stand on its own two feet and proudly say “Look world, I’ve arrived!”

In hindsight, it’s clear Apple at first didn’t know what it wanted the Apple Watch to be. Apple CEO Tim Cook announced the smartwatch as “the next chapter in Apple’s story” at the tail end of its iPhone 6 event in 2014. With each new Apple Watch model, Apple started to key in on what differentiates the smartwatch from an iPhone. Above all else Apple has emphasized fitness and wellness, and with the new Apple Watch Series 4, the company is going even further, positioning it, at least partially, as a medical device that watches your health so you can live a healthier (and hopefully happier) life.

The Apple Watch Series 4 stays connected to the outside world via Wi-Fi or a wireless Bluetooth connection to your iPhone. When connected, you can use the watch as an extension of your phone to view text messages, interact with Siri, navigate via built-in GPS, or make handsfree calls with the integrated speaker and microphone.

Generate an ECG Anytime, Anywhere

The built-in titanium electrode in the digital crown and the sapphire crystal electronic heart sensor on the back of the Apple Watch gives you the ability to record your own ECG, or electrocardiogram. It’s similar to a single-lead electrocardiogram and takes only 30 seconds to create. Just touch the digital crown and wait for the Apple Watch to generate your ECG waveform.

The ECG app is meant to help you detect whether your heart’s beating at a normal sinus rhythm, or if your rhythm shows signs of irregularity, or atrial fibrillation. Your ECGs are stored in the Health app on your iPhone and you can share them with your doctor.

Heart Rate Sensor

The optical heart sensor on the back of the Apple Watch is designed to measure and record your heart rate. Irregular heart rhythms (arrhythmias), high heart rates, and low heart rates, can all be indicators of a possible underlying problem. The Apple Watch is engineered to monitor this reading and alert you to any irregularities.

Fall Detection

The Apple Watch Series 4 features an updated accelerometer and gyroscope that can detect whether you’ve fallen. If a fall occurs, the Apple Watch delivers an on-screen prompt where you can swipe to have it call emergency services or dismiss it. After 60 seconds of unresponsiveness, the Apple Watch will place the call automatically and send a message to your emergency contacts.

Emergency SOS

Emergency SOS allows you to quickly get help. It notifies emergency contacts, sends your current location, and displays your ID on the screen for emergency personnel.

Complications

You can customize your watch face with multiple complications, which are little icons that are designed to activate apps or provide information. The Series 4 infograph watch face can display up to eight complications, including complications with curved progress bars and gauges.

Activity Rings

Apple Watch Series 4 is so nicely designed that three activity rings to help you to measure all of the ways you move throughout the day. As you move, each ring begins to close, giving you additional motivation to close your rings and increase mobility.

Move: The Move ring shows you how many active calories you burn. Active calories are the ones you burn through daily activities, from taking the stairs at work to playing with the kids.
Exercise: The Exercise ring shows you how many minutes of brisk activity you’ve done, whether you’re working out or just moving at a fast pace.
Stand: Sitting too much has the potential to contribute to health problems over time. This ring is designed to keep track of the amount of times you stand throughout the day.

Workout App

The Apple Watch Series 4 lets you track your workout progress, set individual goals, and measure your calorie burn with the Workout app. For runners, a cadence metric lets you see your steps per minute, and rolling miles allows you to see your split for the preceding mile at any time.

Automatic Workout Detection
