Apple WatchOS 10, set to be released later this year, is the most significant overhaul of the device’s user interface since it debuted almost a decade ago. It it also the latest instalment of Apple’s most intriguing, on-going design story. With a mission to rationalise and clarify the way we use a device far more capable and multi-functional than it was at launch, Apple has dramatically improved the look and user experience of Apple Watch in the process.

Apple Watch’s design, hardware and OS, has always been about the tension between possibility and constraint. As Apple Human Interface designer Gary Butcher explains, the design of the Apple Watch OS has to allow access and control of an ever-increasing arsenal of tricks, tools and capabilities on a small display and to do it with short and intuitive interactions. And while the Apple Watch boasts a touch screen, the ambition has always been to find the optimal balance of screen and hardware controls, without muddying the sleek case design with multiple sticky-out buttons.

The Apple Watch’s key innovation and functional focal point was and is the Digital Crown. Over time though, the watch’s app ecosystem has grown and grown more complex, as has usable screen real estate, and the mix of touch and crown scroll manoeuvrings has grown more variable and confusing. For OS10 every Apple Watch app has been redesigned to restore order. These redesigned apps now make smarter use of the entire display and corner icons and how have a far more consistent look and interactive logic.

The more information-rich apps, such as Activity, now offer Vertical Pagination which allows you to access distinct and colour-coded infographic screens rather than a fussy infinite scroll. The Weather app in particular has been given a serious upgrade in looks and functionality. In other apps, the Digital Crown now has extra functional oomph. In World Clock you can now scroll through the day - with screen colour helpfully moving from darkness to light - taking the tricky head-maths out of out scheduling inter-continental video conferencing.

The update also makes smart use of background colour to convey information. If the Noise app is green, it’s all good but if it turns yellow, reach for the ear plugs. And the subtle use of translucency instantly establishes hierarchy of information.

A new feature in Apple Watch OS10 is Smart Stack, a rolling, almost 3d-in-effect display of App widgets that throw up bite-sized chunks of useful and well-timed information. Smart Stack can be surfaced on any watch face with turn of the Digital Crown or a simple up swipe.

Powered by the ‘relevancy engine’, Smart Stack has been designed to roll out only useful information at a useful time, from morning weather forecasts to calendar reminders and tickets and boarding passes when travelling. It also allows instant access to other apps at work at the same time, such as music or podcasts. You can add your preferred widgets to the information flow and some apps offer alternative widget layouts. The widgets have again been colour-coded while the three-dialled Combo Widget is a useful multi-tasker. (Apple is also offering external developers a choice of six different widget templates).

Snoopy and Woodstock have now joined the list of IP with their own Apple Watch face but with new levels of interactive engagement, employing 148 unique animations, which sees them playing with the watch hands, reacting to weather conditions and getting active when you get active.

In what Butcher admits is a ‘super nerdy’ move, the Snoopy face’s default mode is Sunday Surprise which means that the background is a grey halftone Monday through Saturday but bursts with colour on Sunday, a nod to an era when coloured newsprint was a weekend-only treat.

Apple Watch offers other geeky pleasures of course, and WatchOS 10 offers advanced new metrics for cyclists. When a cycling workout is started on the watch, a simple tap will activate a full-screen Live Activity display on iPhone and the upgrade means an Apple Watch can automatically connect to Bluetooth-enabled cycling accessories such as power meters and speed and cadence sensors.

For hikers, the Compass app will now add a Waypoint for the last place on the trail with cellular reception and a Last Emergency Call waypoint will estimate the last connection to any available carrier network. And a new Elevation view offers a three-dimensional view of saved waypoints.

WatchOS 10 also offers more in the way of mental health tracking. Moods and emotions can now be logged in the Mindfulness app. And as of iOS17, the iPhone Health app will track how your state of mind correlates with lifestyle factors such as time spent in daylight, sleep, exercise and ‘mindful minutes’.

Overall, Apple Watch OS10 is a deep and wide rethinking of Apple Watch’s UX. App design is at once richer but cleaner and less cluttered and much closer to iPhone apps in look and feel while the information offered hits the sweet spot between useful and overload.
