The Apple Watch Series 12 and its big sibling, the Apple Watch Ultra 4, were the latest wearables announced alongside the iPhone Duo at Apple’s ‘Surprise and Shine’ event, and the array of new health features haven’t let me down.

Though I didn’t get the design upgrades I was hoping for (I wanted Apple to do a 180-degree turn and debut a completely fresh look for its watches), we got some smart new color options in the process. But that aside, the new monitoring tools do more than make up for the lack of visual upgrades — they’re smarter, insightful, and more personal than ever.

It’s hard to tell if all the new wellbeing tracking tools will be available for previous models — for anything powered by Apple Intelligence, it’s likely that these will remain native to the Series 12 and Ultra 4 — but we still think they’ll make for welcomed additions for health-conscious users.

On-camera fitness testing

As part of the wider Health app revamp, health monitoring using the Apple Watch paired with the iPhone's camera is a new feature, starting with full body assessments. The assessments allow the Health app to measure VO2 max — the the maximum amount of oxygen your body can use while exercising, a key measure of fitness — along with flexibility, strength, balance, and movement mechanics.

All you have to do is prop your iPhone vertically against a wall so that your whole body fits in the frame, and it will get you to follow a coach-guided workout. Apple says in order to measure VO2 max, you’ll need an Apple Watch, AirPods Pro 3, or a third-party heart rate sensing device.

Health Age

Apple is slightly behind on the Health Age feature — Garmin and Whoop got there first with Fitness Age and Whoop Age, respectively — but it’s finally coming to Apple Watch.

Health Age can be found under the new Longevity tab in the Health app, a hub for displaying deeper insights for different health topics including heart health, mental wellbeing, nutrition, and hearing health.

Your Health Age reading takes different aspects of your health profile into account and combines them into one score to show how your metrics compare to the average health and fitness level for your age and gender.

Health Sensing System

This is a technical upgrade to the Apple Watch itself, and a welcomed improvement to how the wearable reads your health data.

Both the Apple Watch Series 12 and the Apple Watch Ultra 4 come fitted with new LED sensor arrays designed for better skin contact, including a new heart-rate sensor for more accurate heart rate and heart rate variability (HRV) measurements — which helps to determine the new Readiness score, which we'll discuss in a moment.

Under the new sensors are larger green LEDs, which now measure your heart rate up to every five seconds, all day long. Apple claims that it's the most accurate heart rate measurement on any wearable, and it can back this up with testing results. We can't wait to try it ourselves against an electrical heart rate monitor.

Readiness Score

Much like the Health Age metric, the new Readiness Score is a tool that's been widely adopted by rival wearables in the past — and now it’s Apple’s turn.

Diving into your Vitals, Sleep Score, recent activity, and other metrics, you'll be presented with a score from 0-10, along with a brief explanation to tell you if your watch thinks you need to pace yourself, or if you have the capacity to push yourself further.

It's a clever and handy tool that could stop you from overtraining, or change your plans to fit in a long run on a day in which you're ready for action. Readiness also updates multiple times a day as your Apple Watch gathers new data, telling you exactly what's affecting your overall score.

Insights tab

The Health app's new Insights tab looks very comprehensive. Throughout the day, Insights displays timely information about your health metrics including heart, sleep, readiness, fitness, vitals, and cycle tracking data.

It gives you short summaries about how different fitness categories are impacting your long-term health, while the 'For You' section offers personalized recommendations and even relevant health articles based on your data.

• Hands-on images show a visible crease on the new iPhone Duo
• It can be seen when the device is held at certain angles and in different lighting
• While Apple hasn't quite solved this common issue, its nano-texture layer significantly helps to reduce visibility

Apple finally unveiled the iPhone Duo at its ‘Surprise and Shine’ event, its first device in the foldable phone market, and from our first hands-on experiments with it I have to say, it looks rather impressive.

And yes, Apple has taken its sweet time to launch its first foldable (Samsung was ahead of the game in 2019 with the first Galaxy Fold device), but that’s likely due to Apple’s determination to solve one of the most annoying setbacks with folding phones — the display crease.

In the build-up to the iPhone Duo announcement, rumors suggested that the device’s folding display wouldn’t come with a visible crease. However, early hands-on images appear to show that Apple might not have quite got the results it was looking for.

It hasn’t even been 24 hours since the iPhone Duo was announced, and Redditors are already pointing out its partially visible crease, which you can see when the device is held at different angles and in certain lighting (see below).

I’m not one to be picky, but despite the matte smoothness of the folding nano-texture display — which helps to significantly reduce the visibility of the crease — there’s a clear vertical dip that runs through the centre of the iPhone Duo’s 7.6-inch screen. Apple knew this would be one of the most-asked questions, and the company has come equipped with all the answers you could need on the iPhone Duo product page.

‘iPhone Duo features a wonderfully flat and smooth inner display with custom nano-texture finish technology to reduce glare and reflections for an uninterrupted viewing experience. The optically clear adhesives let the display layers glide as the screen folds, minimising stress and creasing’.

Unfortunately, Apple hasn’t quite hit the nail on the head with overcoming one of the biggest obstacles with folding phones, but at the same time, eliminating the crease entirely is almost an impossible task. Think about it: if you’re constantly folding and unfolding the device several times a day, then this is going to have an obvious visual impact on the device over time — which is the case for all foldables.

Luckily for Apple, it appears that users aren’t entirely concerned with the slight visibility of the iPhone Duo’s crease.

Several owners of foldable phones shared on Reddit that once you’ve used a foldable for some time, the crease becomes invisible to you simply because you just get used to it being there. Others have been a bit more abrasive: ‘I'll never understand the people who make the crease a big deal,’ one user added, while another simply commented ‘I have a folding phone. The crease is a complete non-issue’. They must be a Galaxy Fold owner, surely.

Criticism aside, our first hands-on with the iPhone Duo was far from a let down. Our Editor-at-Large, Lance Ulanoff, recalls having very minimal issues with the device’s crease. From our first-look images, the crease is unidentifiable when the phone is held face-on, and the matte display helps to get rid of that annoying glare.

For its first foldable phone I have to say, Apple has done pretty much all it can for it to join the folding device market seven years behind its biggest rivals. Despite the lack of features such as Face ID and Action Button, the iPhone Duo looks like a solid beginning for Apple’s next big venture — even if I’m not the biggest fan of the name.

Apple's 'Surprise and Shine' event unveiled long-awaited devices including the iPhone 18 Pro and the long-anticipated iPhone Duo, but Apple Watches also had their time in the spotlight.

The Apple Watch Series 12 and Apple Watch Ultra 4 are the latest models to join Apple's family of wearables, and both pack quite a punch on the features- and health-tracking front, thanks to the combination of the new Health Sensing System and deeper Apple Intelligence integration.

Of course every new Apple Watch offers improvements over the previous generation — the question is always whether it offers enough to make it worth the upgrade. To help you decide, I've compared the new Apple Watch Series 12 against its predecessor, the Apple Watch Series 11, so you can see all the changes side-by-side.

Apple Watch Series 12 vs Apple Watch Series 11: Specifications

Design

We weren't expecting a visual overhaul with the Apple Watch Series 12, and nor did we get one.

The new model packs the same digital crown and side button that you'll find on most Apple Watch models, and size-wise the only difference is that the Series 12 is 1mm wider; if you can spot that in real life, you have sharper eyes than I do.

However, there are some design changes worth talking about. The key one is that as well as being available in Aluminium and Titanium, as the Watch 11 is, there's also now a Ceramic version — the first since the Series 5.

The Ceramic Watch 12 comes in two colors, Pearl White and Night Blue, while the Aluminum model is available in Space Gray, Black, Light Gold and the stunning new Dark Bronze shade, perfect for both casual and smart wear. The Titanium versions come in Radiant Gold and Natural.

Sticking with the Apple Watch 11? Then your choices are between Space Gray, Jet Black, Rose Gold, and Silver for Aluminum, and Slate, Gold, and Natural Polished in Titanium. And to reiterate, there is no Ceramic Watch 11 — so if you want that, you'll need the new model.

Features

Minor design changes aside, the key reasons to upgrade to the Apple Watch 12 relate to its health-tracking smarts.

Many of these stem from its new S11 chip. Apple — inevitably — describes this as its "most powerful wearable chip", and it powers the new Health Sensing System and Audio Intelligence features.

Let's start with the Health Sensing System, the redesign of the previous generation's LED heart rate sensor array. The Series 12's electrode surface area is now bigger, allowing for better skin contact for ECG tracking. It also packs new optical-sensing photo diodes to capture light more efficiently, while its brighter green LEDs support accurate HR in motion. In short, it's the most accurate Apple Watch ever, tied with its sibling the Apple Watch Ultra 4.

It records heart rate continuously, up to every five seconds, and heart rate variability (a key part of sleep tracking and recovery metrics) up to every five minutes. That's a massive 24x more frequently than it did before, ensuring peak accuracy (in theory).

However one of the new standout features is the new Readiness Score, which has finally arrived on Apple Watch. Every other health wearable seems to have one, and Apple's Readiness Score will combine your rings, vitals and other health metrics into a single actionable, frequently updated number.

There are also a significant redesign of the Health app which thrusts Apple Intelligence to the front of the experience. Now, Apple Watch lets you explore health profiles while offering personalized guidance thanks to Apple Intelligence. Once the Health app gets a sense of your health habits, it will tweak its recommendations so that they align with your health levels and data.

Health Age is another new feature that aligns your metrics and fitness level with your actual age, similar to features on Whoop and Garmin.

The Series 12 is packing tons of new fitness features, but Apple Intelligence — or at least, audio intelligence — is brand new and unrelated to health.

Audio Intelligence is comprised of four features. The Series 12 can listen out for sounds, be that a doorbell, traffic, or oncoming pedestrians, and will send alerts right to your watch face — which is ideal for users who are hard of hearing. You can also Shazam songs from your wrist.

Slightly more suspect are Live Rewind and Siri Recaps. Live Rewind allows you to go back 15 seconds to remember parts of a conversation. Didn't catch what the waiter said was new on the menu? Just double-press the digital crown and your watch will generate a transcript for you to read. Siri Recaps is a feature that, when active, listens constantly in the background, providing you with a summary of your day in the evening, including conversations.

We've covered these two features in more detail here, including Apple's privacy assurances and why the Cupertino giant might not be reading the room on this feature, as surveillance-capable wearables are receiving a lot of pushback at the moment.

You can pre-order the Apple Watch Series 12 now, which will be available starting September 18.
