Apple Watch may help find your watch, track your sleep, and monitor your blood sugar

The Apple Watch may be the undisputed king of smartwatches, but that doesn’t mean it’s perfect — a particularly big annoyance we encountered in our review were third-party app slowdowns and crashes. Thankfully, 9to5Mac reports that a forthcoming update should remedy those issues and others with enhancements to fitness and health tracking, a new watch-finding app, and a range of other fixes aimed at stability.

As Apple works towards the release of tools later this year for native, hardware-accelerated Apple Watch apps, a source tells 9to5Mac that Apple will open complications — the tiny date, weather, and battery life widgets on watch faces — to third-party tinkering. According to the report, the Cupertino-based company’s been working with Twitter on an unread tweet counter icon.

It’s unclear exactly to what degree users will be able to customize complications and just how they’ll go about obtaining new ones. Right now, the Apple Watch lacks a storefront for watch faces and limits the degree to which complications can be changed — it’s implausible that, at least initially, getting new complications will require downloading entirely new watch faces.

The addition of “Find My Watch” looks to address the glaring absence of watch-finding functionality. Just like the app Google recently introduced on Android Wear, Find My Watch will let users lock, wipe, and track their wearable. Intriguingly, though, it goes a few steps further than comparable implementations — a feature known as “Smart Leashing” will notify users if their Apple Watch loses connectivity with a paired iPhone. It’ll also somehow rely on Wi-Fi to pinpoint its location, although that functionality might debut with a second-generation Apple Watch — it reportedly requires a wireless chip more capable than the one found in current-generation models, 9to5Mac says.

Separately, Apple’s beefing up the watch’s wellness capabilities. The company’s been experimenting with arrhythmia detection features that would notify a wearer in the event of an irregular heartbeat, but for now has put those functions on hold over liability and regulatory concerns. (The FDA published guidelines in January suggesting smartwatches that diagnose and treat illness would be subject to increased scrutiny).

Apple also planned to add oxygen-saturation tracking and blood-sugar monitoring, but opted to incubate the necessary sensors for a future model. In lieu of those, though, sources tell 9to5Mac a future update will bring blood-pressure monitoring and sleep tracking to the Apple Watch.

Sadly, a timeline for the aforementioned updates is nonexistent, but considering the close proximity of WDDC, a preview of a few of the new features — and if we’re especially lucky, a release date or developer preview — isn’t entirely unlikely.

The best Apple Watch Series 6 tips and tricks
Apple Watch Series 6

The combination of the Apple Watch Series 6 and WatchOS 8 software is powerful. The last generation Apple Watch comes with a variety of useful features that can help in your daily life -- if you know how to use them. We offer a list of our favorite tips and tricks for getting the most out of the Series 6 in conjunction with WatchOS 8.
Zoom in and out using the Digital Crown
The Apple Watch Series 6 lets you zoom in or zoom out to have a closer look at the contents of your watch face. To use it, open Settings and scroll down to Accessibility. Tap to open it, and you’ll see the Zoom control, which is off by default. Toggle the switch on to launch Zoom and then double-tap on the screen using two fingers to enable size adjustments with the Digital Crown. You can also use the settings to specify the maximum amount of zoom you want. To zoom out, double-tap on the screen using two fingers and it will return the screen to normal viewing.
Ring your iPhone
Where, oh where, is your iPhone? If it's in silent mode and you've misplaced it, you can use your Apple Watch Series 6 to ping it. Open the Control Center on your watch and tap on the iPhone button. Your iPhone will then make a loud dinging sound -- even if it is silent mode -- signaling precisely where it is located.
Use your watch as a camera remote
Open the Camera Remote app on your Apple Watch 6 to automatically launch the Camera app on your iPhone. Then tap the shutter button on your watch or use the timer to snap a picture.
Use the always-on display more effectively
The Apple Watch Series 6 has an always-on display, which allows it to show useful alerts and data without the need to activate or unlock. With Series 6, the always-on display is much brighter than previous models and incorporates direct control capabilities. You can tap for basic features  -- complications, notification center, and Control Center without unlocking the watch.
Activate Siri with wrist motion
Do you give Siri commands via the Apple Watch? The Series 6 has a super-handy intuitive feature for this -- simply lift your wrist at any time and say your Siri command -- no need to say “Hey Siri” first. The wrist motion automatically lets Siri know it’s all right to start listening, without unlocking the watch, so you can give immediate commands or ask quick questions.
Track blood oxygen levels
For the Series 6, Apple redesigned the way it measures certain health indicators and added the ability to measure your blood oxygen levels (or Sp02 data). You can find this option in the Health app under Respiratory information, or you can visit the dedicated Blood Oxygen app within the WatchOS. Your Watch also monitors background blood oxygen levels several times a day, which allows you to check how much oxygen your body is getting over time. While this shouldn’t be used to diagnose any specific condition, it can offer insight into overall respiratory health, which your doctor may be interested in checking, alongside other testing.
Use the improved altimeter
Apple redesigned the altimeter in the Series 6 to track your elevation and provide real-time elevation changes via a more powerful, accurate sensor. The tool is much more useful to hikers, climbers, skiers, and even surveyors for tracking real-time elevation changes, even if it’s just a foot or two of difference.
Control universal volume with the Digital Crown
Digital Crown is the fancy name for the large rotating dial on the side of the watch that you use to go to the home screen. On the Series 6, any time you are in Now Playing mode for any kind of audio, you can twist the crown to control the volume.
Theater mode controls screen brightness
If you are ever in a location where you need to lower the light or noise from your Apple Watch, the Control Panel now includes a Theater Mode option that enables your watch's silent mode. Activate it to keep the screen dark regardless of alerts or notifications. If your Apple Watch suddenly starts making noise or disrupting a meeting, just cover it with your palm. The Watch will sense this and automatically stop this action, leaving you to carry on in peace.
Wash your hands with confidence
Hand washing has become a critical health protector, and the Apple Watch Series 6, combined with the WatchOS 8, can play an important role. It uses the array of sensors to detect when you are washing your hands -- listening for running water and hand movements, for example -- that initiate a hidden 20-second timer for your handwashing action. If you stop before the 20 seconds are up, the watch sends a quick vibration to signal you to keep going. The 20-second goal is a guideline both the WHO and the CDC agree on.

What you can (and can’t) do on your Apple Watch without your iPhone
Apple Watch Series 7 in a pocket.

The Apple Watch has seen enormous success. In fact, it’s the most popular item in Apple’s quickly expanding Wearables, Home, and Accessories division, which also includes Apple AirPods.

Since the Apple Watch was released in 2015, the smartwatch has gone through a number of makeovers and gained several new features. People love the Apple Watch for its durability, water resistance, and fitness-tracking abilities. Early versions of the watch could measure your activity levels, heart rate, and several other health metrics. Later versions even come with tools like ECGs (electrocardiograms) that can tell you when your heartbeat is abnormal and oximeters that can measure your blood oxygen levels.

How to build a fun and varied Apple Watch band collection
A collection of Apple Watch bands.

You could just buy an Apple Watch and only ever use the band that comes with it, but to ignore the amazingly varied world of bands, straps, and bracelets available would mean missing out on the chance to truly make it your own. Building a small collection of bands means your Apple Watch never looks out of place with what you’re wearing or the activity you’re engaged in, and it keeps things fresh and interesting.

If you’re new to the Apple Watch and aren’t sure where to start, I’ve spent a little time building a core collection of bands that I find are suitable for all situations. If you do the same, get ready to change the band on your Apple Watch on a very regular basis. I assure you it's worth it.
A band apart
What’s wrong with the basic Apple Sport Band or Sport Loop that comes with most Apple Watch models? Absolutely nothing, and one of these bands is so good it makes it on to my essentials list. It’s limiting yourself just to this one band that I’m suggesting you avoid. Changing the band on the Apple Watch isn’t time-intensive, there’s no risk of losing bits when you take it apart, you don’t need any special tools, and the end result is a completely different look and feel on your wrist.
