Designing better UX for Apple Watch apps.

Let’s jump straight into it, because the proverbial clock is ticking. The first thing you need to know is that designing for Apple Watch is not about shrinking a mobile experience to fit a smaller screen. It’s about shifting perspective: designing not for the device, but for the moments when the device matters most. The moments that are too brief, too subtle, or too inconvenient for a phone.

Throughout exploring Apple’s Human Interface Guidelines and dissecting the unique nature of wrist-based interactions, I came to one conclusion early on: designing for watchOS isn’t a “less is more” kind of exercise, but a “faster is more” mindset.

Here’s why: people don’t scroll endlessly on a watch. They glance. They get nudged. They tap once or twice and move on. They check their wrist while crossing the street, during a workout, in the middle of a conversation, or while cooking. They’re doing other things, and the watch is simply there, helping… quietly, quickly, efficiently.

This was the real constraint, and the real opportunity for innovation. Next, I’ll uncover some relevant insights and explore key Apple Watch features.

People typically choose their watch when:

• They're in a hurry and need info fast;

• Their hands are busy with other things;

• They want to check something discreetly without the social disruption of pulling out a phone;

• They need immediate alerts for time-sensitive stuff;

• They're in situations where using a phone is awkward or impossible (workouts, cooking, holding a baby).

Designing for speed, not screen size.

Apple Watch is a companion people turn to because it’s immediate. There’s no digging through pockets or unlocking, just a flick of the wrist and a few seconds of attention.

Those seconds matter. According to Apple, most watch interactions last between two to three seconds. Not minutes, seconds! That’s all the time your design has to be clear, useful, and gone again.

This makes clarity a non-negotiable. Interfaces need to support fast interpretation, single-screen flows, and gestures that feel natural: whether it's a tap, a turn of the Digital Crown, or simply a raise of the wrist. The watch also supports AssistiveTouch gestures, like pinching or clenching, which adds a layer of accessibility and control. Designing for this wide interaction surface, and not just the screen, is fundamental.

People control their watches with:

• Digital Crown

  • Rotation: Turning the side dial to scroll, zoom, or adjust settings

  • Press: Pressing the crown to access the home screen or app grid

• The Side Button: Press for apps, double-press for Apple Pay, long-press for powering off

• Taps & Swipes: just like on a phone, but on a tiny screen

• Long press: Pressing and holding to access context menus or customisation options

• Voice: Siri handles the heavy lifting when hands are busy

• Wrist raise: Lifting your wrist to wake the display

• AssistiveTouch gestures: Pinch and double-pinch gestures for accessibility features

• Double-clenched fist: For those with AssistiveTouch enabled

• Quick Actions: Pinching your index finger and thumb together (on newer models)

• Handoff: Bringing your watch near your iPhone to transfer tasks between devices

• Cover to mute: Covering the watch face with your palm to silence notifications

The real product lives outside the app.

One of the most fascinating aspects of watchOS design is how little time users spend in the app. What truly defines a watch experience are the surfaces surrounding it: complications, widgets, notifications, the Smart Stack and Live Activities.

Complications, for instance, are arguably the most powerful way to deliver information. Tiny by nature, but mighty in purpose, they sit directly on the watch face and update in real-time. These are the elements users see most often — about 60 to 80 times a day, albeit for just a blink. That makes every pixel count.

Smart Stack, introduced with watchOS 10, adds another layer of relevance. Instead of static widgets, the Smart Stack shows dynamic cards based on the user’s location, time of day, and behaviour. It’s context on a timeline, and it allows your app to show up when it matters most, not just when it’s opened.

Live Activities take it further, offering real-time feedback for ongoing processes: timers, deliveries, progress updates, without stealing the whole screen. And with the always-on display on newer models, even when the wrist is down, essential info can remain visible in a toned-down, battery-friendly state. Designing for this persistent-yet-subtle presence is as much about restraint as it is about function.

Designing holistically.

Our design systems keep things consistent across devices, so we can move faster, stay aligned, and never compromise on quality.

A deeper dive into key Apple Watch features.

Watch Faces.

A watch face is the main screen of an Apple Watch. It’s what people see every time they raise their wrist. Apple lets users customise it with Complications, which are small widgets that show live updates from different apps.

Complications

People check their watches a lot — about 60-80 times daily — but most of these glances last just 2-3 seconds. This is why "complications" (those little info snippets on watch faces) are so powerful!

Complications are like tiny windows into apps that live right on the watch face, coming in various shapes:

• Small and large circles

• Small and large rectangles

• Corner positions

• Edge elements that stretch along the sides

Further insights

• "Design a complication that unobtrusively provides useful information at a glance.", Apple Human Interface Guidelines.

• “Use complications to provide relevant, potentially dynamic data and graphics right on the watch face where people can view them on every wrist raise and tap them to dive straight into your app.”, Designing for watchOS.

• “People place watch complications on the Apple Watch face to view timely, relevant information when they lift their wrist. Additionally, the Smart Stack on Apple Watch offers space for up to three complications.”, WidgetKit Framework.

Home Screen & App Icon.

Unlike complications that show quick info, the app icon launches the full app experience:

• Icons appear in the honeycomb grid or list view (user preference)

• App icons are circular and need to be distinctive at small sizes

• Icons can indicate status with badges or by changing appearance

• Users arrange icons to prioritise frequent apps

• Recently used apps appear in the Dock (accessed via the side button)

Notifications & Alerts.

Watch notifications need special attention because a tap on your wrist feels more immediate than a phone buzz in your pocket.

Apple Watch notifications work in two stages:

• First, a quick "short look" appears when you raise your wrist

• Keep looking, and you'll see the "long look" with more details and action buttons

What's great is you can respond right from these notifications - reply, dismiss with a swipe, or use voice commands. Perfect for busy people who need to handle things quickly.

Apple's guidance is spot-on!

"Design minimal, relevant notifications that make it easy for people to get the information they need with a quick glance."

Always-On Display (for newer watches).

The newer Apple Watch models have this great feature where the screen stays partially visible even when your arm is down. It's dimmer and simplified, but still shows important info.

In this always-on state:

• Your essential info remains visible but toned down to save battery

• The display updates once a minute

• Animations and visuals are simplified

Smart Stack.

With watchOS 10, Apple introduced Smart Stack - think of it as a pile of info cards that appears when you turn the Digital Crown.

What makes Smart Stack special is how it shows different information based on what you're doing, where you are, and what time of day it is. It's like having a tiny assistant that brings up the right info at the right moment.

Live Activities: keeping track of ongoing events.

Live Activities are Apple's way of showing real-time updates for ongoing events. Think of it like having a tiny live window into active processes.

They're perfect for:

• Timers counting down

• Progress bars filling up

• Status updates that change frequently

How does it work?

When you're using an app, the Live Activity appears above the app’s content. It doesn’t take over the entire display but remains visible so users can stay updated without leaving their current task.

• The Live Activity widget appears above the app’s content.

• It updates in real time with essential info

• Tapping the widget can expand the Live Activity or take the user to the main app view

• If dismissed, the Live Activity remains accessible in the Smart Stack

Navigating navigation.

There’s no single navigation model for watchOS. It adapts depending on the use case: hierarchical structures, vertical scrolling, tabbed views, or horizontally swipeable pages.

The key is to keep transitions smooth and expectations consistent. Users should never wonder where they are or how to get back. Scrollable views should feel intuitive with both the finger and the Digital Crown. Tabs should signal clear categories. Pages should be limited and focused. And when in doubt, keep things linear. The moment navigation becomes a cognitive load, the moment you’ve lost the moment.

Apple’s approach to backgrounds in watch apps also reveals a lot about their philosophy.

Background content.

Backgrounds aren’t there to decorate; they’re there to signal. Colour gradients, subtle patterns, and dim overlays provide just enough depth to communicate state, without ever pulling focus from content. When used sparingly, they elevate legibility. When overused, they drown it. They provide important context and help users understand the app's state. This is why Apple treats background elements as a key part of the information hierarchy:

• Colour backgrounds can indicate status or mode (red for alerts, green for active sessions)

• Gradients can add depth and visual interest without competing with foreground content

• Subtle patterns can help differentiate functional areas of the interface

• Background imagery must be extremely minimal to avoid cluttering the small screen

• Dark backgrounds are generally preferred to conserve battery and enhance readability in various lighting conditions

Beyond copy-paste.

One of the biggest questions when designing for watchOS is what not to bring over from mobile. The answer isn’t always obvious.

What makes sense on a phone might feel clunky on the wrist. The decision to include a feature should be based on five filters, and if it fails most of those, it probably belongs elsewhere.

WatchOS apps are not about feature parity, they’re about feature priority. You’re not here to recreate the mobile experience. You’re here to support it when it’s inconvenient to use the mobile experience.

Defining mobile to watch features.

• Time-sensitive value

  • Include features needed in the moment

  • Skip features that can wait for phone access

• Glanceability

  • Include information that works at a glance

  • Skip complex data requiring extended viewing

• Hands-free necessity

  • Include features needed when user has their hands full

  • Skip anything requiring focused attention

• Completion in seconds

  • Include tasks completable in under 30 seconds

  • Skip multi-step processes requiring concentration

• Frequency of use

  • Include daily/hourly actions

  • Skip rarely used features

Designing for intuition.

Designing for the wrist forces a shift in mindset. It asks you to set aside assumptions about features, screens, or even "apps" in the traditional sense, and instead focus on moments. Micro-moments. The kind that last two seconds, are often hands-free, and disappear before you even realise they’ve happened.

And that’s where the beauty of designing for watchOS lies. It’s a test of clarity, not complexity. You’re working with limited space, attention, and interaction, but within those constraints, you have a rare opportunity to design something that’s not just useful, but intuitive. Something that fits so naturally into a person’s routine that it ceases to feel like a tool and becomes more like a sense: always there, never in the way.
