Apple took the wraps off watchOS 5 last week at WWDC, revealing loads of new features that we can look forward to this fall. Among them were some big improvements for runners: Cadence, Rolling Mile Pace and Custom Pace Alerts.

What I find most exciting about these new features is that I think they hint at a much-needed hardware upgrade coming in Apple Watch Series 4, which is expected to debut this fall. Here’s why.

Imagine if your Apple Watch could tell you which days were best for you to do a workout, and what kind of workout you should do. Well it can, sort of, thanks to a hidden feature that few people have yet discovered or know how to use.

Heart rate variability, or HRV, is a new metric that reveals your stress level and whether you have recovered from your last workout. It has been added to lots of high-end sports watches in recent years, including Apple Watch since watchOS 4 & iOS 11.

Here’s how you can use it to optimize your training, reduce your risk of injury, and know when to take a well-earned rest day.

The Activity Rings on your Apple Watch don’t provide a complete picture of your fitness. There is one important ring missing: Strength. The Rock didn’t get ripped just by standing up once an hour. And both the Exercise and Move rings essentially measure the same thing: cardio.

As any fitness expert will tell you, an effective workout program should combine cardio with strength training. Here’s why strength is currently Apple Watch’s weakness, and how you can use third-party apps to make sure it isn’t yours as well.

For activity tracking, fitness and notifications, Apple Watch is pretty awesome, and these days, that’s all most people use it for. Which is a shame.

When it launched back in 2015, Apple had a much bigger vision: a wearable computing platform supporting a rich and varied ecosystem of apps. Like an iPhone strapped to your wrist. But the reality has turned out to be rather different. Instagram is just the latest of a series of high profile apps to desert the platform. So what’s up?

I believe Apple Watch’s dependence on iPhone is holding it back, and the time has come for Cupertino to set its smartwatch free. In this, the third and final part of my wish list of watchOS 5 features, I’ll focus on how I hope Apple will improve setup, apps and iCloud to create a badass stand-alone device.

When it comes to fitness apps on Apple Watch, sometimes it feels like Cupertino is running before it can walk. Fancy new features like Heart Rate Recovery are very welcome, but a few of the basics remain missing.

Apple could make major strides when it releases watchOS 5. So in the second of three posts about the future of watchOS, I’ll focus on five essential fitness features I’m hoping we’ll see at this year’s Worldwide Developers Conference.

In the three short years since Apple Watch debuted, Cupertino has massively improved its smartwatch. Remember the early days, when Glances took ages to load, only to show out-of-date information? When the Fitness app refused to stay in the foreground during a workout? Or when the side button launched a doodling app?

Since the launch, Apple has rolled out big upgrades to watchOS every year at its Worldwide Developers Conference. But there is still loads more that could be done to really unleash Apple Watch’s full potential.

With this year’s WWDC confirmed for June, here’s my wish list of the all the new watchOS stuff I’m hoping will be announced in San Jose, California. It’s a pretty long list, so I’ve broken it down into three separate posts, starting with usability. In followup posts, I’ll focus on fitness, apps and setup.

Are you taking full advantage of all the neat new features in your shiny Series 3 Apple Watch? Cellular connectivity grabbed the headlines, but that isn’t the only hardware addition Cupertino managed to cram into a wearable that was already bristling with sensors.

Apple Watch Series 3 models also boast a barometric altimeter. If you think you don’t need one of those, think again. The altimeter makes Series 3 watches the ideal companion for hill workouts. That’s a type of training you really should be doing but probably aren’t.

BARCELONA, Spain — Smart sperm testers, body cavity inspectors, Bluetooth pillows, holographic jump ropes and contactless thermometers. It’s all just another day at Mobile World Congress, where more and more companies show off their new HealthKit-compatible gadgets.

If you want your iPhone to know absolutely everything about what’s going on with your body, these handy medical devices are for you. Here’s what they do — and why they’re cool.

BARCELONA, Spain — The best product I’ve tried out at this year’s Mobile World Congress is the Vuzix Blade AR glasses. These smart specs superimpose a sharp, high-definition display over your regular vision, making real life resemble an awesome Xbox game.

The Blade basically delivers on everything that Google Glass tried to do, but without sucking. I was skeptical about the rumors that Apple is developing its own augmented reality glasses. But what I saw through the lens of a Vuzix Blade showed me how far this technology has come — and just how cool Apple AR glasses could be.

When the entire mobile phone industry heads to Barcelona next week for Mobile World Congress 2018, there will be one notable absence: Apple.

Cupertino doesn’t do trade shows. Not even really big ones like MWC. Yet, despite its absence from the massive Spanish trade show, Apple’s influence will loom large over Barcelona’s beautiful horizons.

Here are five things Apple fans should look out for at MWC next week.
