Apple Watch is arguably one of the best smartwatches for most of us. The way it fits into the whole Apple ecosystem, its health-tracking features, watch faces, medication tracking, and thousands of other features — it just works. However, there is a niche category of people for whom the Apple Watch may not prove to be the best option, and yes, I am talking about sports athletes and fitness fanatics.

While all the Apple Watch models flaunt dustproof and waterproof designs, it isn’t really an ideal smartwatch for people serious about sports. The display glass, even the “Sapphire crystal display” on the titanium and stainless steel models, is much weaker than the ones found on the likes of Garmin and Fitbit smartwatches. The overall durability is also much lower.

However, this isn’t a drawback as Apple Watch is aimed at people who are not into extreme sports and are attracted by its features, usability, and fashion. But, according to a new report, Apple is working to address the needs of people who want to use the Apple Watch in extreme conditions as the company is planning to release a rugged Apple Watch model later this.

While we already know that Apple is planning to release three Watch models in 2022 — Series 8, SE 2, and a rugged model — Bloomberg’s Mark Gurman has detailed the features and specifications we can expect from the smartwatch. According to Gurman, the rugged model will come with a bigger battery, a rugged metal casing, and a larger display to appeal to the extreme sports athletes.

Starting off with the display, Gurman says that the rugged model Apple Watch will feature a “nearly 2-inch display” with 7% more screen area than the largest Apple Watch available today. While the overall shape is expected to remain the same, the bigger display will feature an improved resolution of 410 pixels by 502 pixels. This display will also be more “shatter-resistant”, due to it being targeted toward extreme sports athletes.

The leaker also believes that the smartwatch will be able to show more information on the display during exercises and workouts, thanks to the bigger display. While the report doesn’t reveal what sort of material Apple will use to improve the smartwatch’s durability, it claims that the smartwatch will be built with a stronger metal than aluminum.

Powering the Apple Watch rugged model will be the same Apple S8 chip that is expected to debut alongside the Series 8 later this year. Previous reports have revealed that the S8 chipset will be nothing but a rebranding of the S7 chipset (which in itself was a rebranding of the S6 chip). Another feature that the rugged model will share with the Apple Watch Series 8 is the ability to take the user’s body temperature and detect if they have a fever.

All of this won’t come cheap. While the report doesn’t mention the exact price tag, Gurman does say that the rugged model will be priced higher than the standard stainless steel model which starts at $699. So, you can expect the price of the rugged model to match Garmin’s Epix 2 price, which retails for around $900 today.

The overall leaked features and specs do suggest that Apple is developing a worthy contender that would be able to withstand extreme conditions. Coupled with Apple’s excellent health tracking features (more coming with watchOS 9), premium build quality, and excellent user experience, Garmin and Fitbit could have serious competition at their hands.

How your watch takes your pulse, blood oxygen, and other vitals

Apple Watch Series 7 Lifestyle Source: Apple

Smartwatches have become an essential part of our daily life. Not only do they help us reduce screen time — by showing notifications and other important info on our wrist — but they also help us keep track of our fitness and body vitals. But, have you ever wondered how such a small gadget is able to measure pulse, SpO2, stress, ECG, arterial stiffness, and other important body vitals? Here’s everything that you need to know!

Blood Oxygen (SpO2)

Apple Watch Blood Oxygen Source: Apple

Blood oxygen or SpO2 level is the percentage of oxygen in the blood. Oxygen, as we all know, is vital for all organs of our body, and SpO2 tells us how much oxygen your red blood cells are carrying. It is considered a key sign that depicts the health of a human body. Usually, blood oxygen lies between 95% to 100%, but if it goes below 90%, it can cause distress in the nervous system, kidney, liver, and other vital organs.

Thankfully, most new smartwatches can measure blood oxygen levels, so in case it starts to fall, you can take precautions and necessary steps to maintain healthy levels. But before we move on to how smartwatches measure SpO2, let’s take a look at how a conventional pulse oximeter measures the blood oxygen level.

SpO2 Working Source: HowEquipmentWorks

Blood oxygen is measured using a technique called Transmissive Pulse Oximetry. In this, a sensor projects red-colored and infrared light onto your skin. The light enters the blood vessels containing oxygen. Haemoglobin, the protein particle of the blood that carries oxygen, absorbs some light and reflects some part of it. The intensity of light reflected depends on how much oxygen it’s carrying (the darker the blood, the less oxygen).

A sensor then measures the amount of light that passes through the sensor and calculates the SpO2 level of your body using algorithms. However, since smartwatches don’t have a receiving sensor on the other side, they rely on a different technique called Reflectance Oximetry. In this, a sensor on the smartwatch measures the difference between the light emitted and reflected to determine blood oxygen level.


Apple Watch Series 7

It’s available in 41mm and 45mm models, and it has GPS and cellular versions. The cellular is best recommended for those who want to take calls while out and about and those who want to connect to the internet, make calls while away from their devices.

Heart Rate

Heart rate is another essential indicator that reflects body health. Most modern-day smartwatches come with the ability to measure heart rate. Heart rate (BPM) is essentially the number of times your heart beats in a minute. It varies depending upon the activity you’re doing. For e.g., if you’re in a resting state, your heart rate might be low, but when you’re working out, your heart beats faster, and thus heart rate is high.

The current-gen smartwatches make use of a technology called photoplethysmography, or PPG, to measure heart rate. In this, green light is projected on your skin using LEDs. While the light is being projected on your wrist, a sensor looks for the intensity of the green light that bounces off your skin.

The blood is red in color, which means that it absorbs green light and reflects red light. When your heart beats, more amount of blood flows into your wrist, which means that more green light is absorbed. Similarly, between the heartbeats, there’s less absorption of green light since there is less blood, and thus more green light is reflected. A sensor on your smartwatch looks for the change in the intensity of the green light and calculates your heart rate using a series of algorithms.

In order for the sensor to work as advertised, the watch must be tightly wrapped to your skin — so that it can look for changes more precisely. This is the reason why the reading fails when you don’t wear the watch tightly, as the sensor isn’t able to read the change in intensity of light properly.

ECG

Most of the smartwatches sold today can measure heart rate, but an electrocardiogram (ECG) is a new thing that you’ll find only on premium smartwatches and fitness trackers. Instead of just telling you how many times your heart is beating per minute, ECG tells you how well your heart is working. It can detect the heart’s rhythm and electrical activity and can even help you detect heart problems like atrial fibrillation (AFib).

ECG on smartwatches works on the same principle as the ECG machines found in hospitals. In conventional ECG machines, 12 electrodes are connected to record the heart’s activity. On the other hand, in smartwatches, two external electrodes are used in order to form a circuit, which then records the time and strength of your heart’s electrical signal.

These external electrodes are built right into your watch. For e.g., in the Apple Watch (Series 6 and Series 7), one electrode can be found in the watch’s digital crown, and the second electrode is the ring surrounding the other sensors of your smartwatch. When you touch the digital crown, a closed circuit between your finger, heart, and wrist is formed.

This helps the smartwatch record the electrical impulses and thus form an ECG. Of course, the strength of the signal isn’t as strong as the conventional ECG machine, so smartwatches are embedded with multiple amplifiers circuits and noise remover circuits to enhance the signal. The signal is then processed by multiple software algorithms that help the smartwatch form an ECG.

Stress

Stress is a feeling of emotional or physical tension that can negatively affect a person’s health and well-being. Interestingly, a lot of smartwatches sold today can keep track of your stress levels and help you reduce them. But how does a smartwatch that is already monitoring blood oxygen, heart rate, and many other vitals of your body measure stress as well? Here’s how a smartwatch can tell if you’re under stress.

Smartwatches rely on the Heart Rate Variability (HRV) technology to determine the user’s stress levels. Using this technology, the smartwatch measures the time variation between each heartbeat. The heartbeat of a person goes up when they’re under stress, which leads to decreased time intervals between each heartbeat. Your smartwatch keeps track of the difference in the time interval between each heartbeat and can, hence, determine your stress levels. The lower the HRV, the higher the stress — lower HRV means the time difference between each heartbeat is low.

Fitbit Stress Detection Source: Fitbit

Some premium smartwatches make use of a dedicated sensor to detect stress. Fitbit’s Sense smartwatch comes with the Electro Dermal Activity (EDA) sensor to detect the stress levels of a person. This sensor detects electrical changes in the sweat level of our skin and, coupled with other vitals such as heart rate and sleep, the smartwatch can accurately detect your stress levels.

Most smartwatches that are able to measure stress levels, such as the Fitbit Sense and HUAWEI’s latest Watch GT 3 Pro, also come with features that help you reduce stress. These smartwatches come equipped with a breathing exercise mode that helps the body relax through long breathing sessions, thus reducing stress.

Body Composition

Some smartwatches, such as the Samsung Galaxy Watch 4, can also measure many body composition factors related to your health, such as fat mass, body mass, body water, basal metabolic rate, and more. Samsung says that the body composition sensor on the Watch 4 collects data from over 2,400 points and gives you a virtual picture of your body’s composition.

But how does it work? Well, it’s quite similar to how smartwatches take an ECG. You place two fingers on your smartwatch, thus completing the circuit. The smartwatch then sends low voltage currents to the body. Different elements, such as fat, water, muscle tissue, and bone, interact differently with the electrical signal. The output signal is then passed onto Samsung’s proprietary algorithms, and the users get results comprising of their individual factors.

While experts say that we should not (only) rely on smartwatches for measuring our body vitals, some studies have shown that smartwatches have become quite reliable than before. The sensors and algorithms have improved, leading to much better results. Of course, smartwatches cannot replace medical-grade instruments, but they have come a long and have proved to be a life savior in some cases.

And oh, while we’re on this topic, make sure you check out my colleague Anton D. Nagy’s piece on why you should stick to just one fitness tracker for best results.

Samsung Galaxy August 2022 Unpacked Event

Source: Evan Blass, 91Mobiles, OnLeaks x Smartprix

Samsung announced that it’d be holding its upcoming Samsung Galaxy Unpacked event on August 10, where it’s expected to introduce the new Samsung Galaxy Z Fold 4, Galaxy Z Flip 4, Galaxy Watch 5 series, and the new Galaxy Buds Pro 2 wireless earbuds. While we have most information about the upcoming products, we didn’t have any leaks on the pricing up until now.

We shared a report earlier, claiming that Samsung could reduce its profit margin on the upcoming Samsung Galaxy Z Fold 4 and Z Flip 4 series of foldable devices, to make them more appealing to a larger target audience. The cut in the profits would’ve meant less money for Samsung, but it could have sold more units. Now, it looks like that might not be the case, and the prices might indeed go up after all.

According to a new report from PriceBaba, the Galaxy Z Flip 4 will set customers back by €1,080 for the one with 128GB of storage. The 256GB model will reportedly cost €1,160, while the 512GB model should retail for €1,280. For comparison, the Samsung Galaxy Z Flip 3 launched for €1,049, and given the current events, inflation, and the post-pandemic world; we’re not too surprised by the slightly higher price tag.

The Samsung Galaxy Z Fold 4 will reportedly (via Gizpaw) come with 256/512GB model variants, starting at €1,864 and €1,982, respectively. That’s a €64 and €82 increase compared to the Galaxy Z Fold 3 announced last year.

The Galaxy Watch 5 and Galaxy Watch 5 Pro smartwatches will be available in multiple sizes and models. The standard Galaxy Watch 5 40mm Bluetooth version will reportedly (via DealNTech) start at €259, while the 44mm model will retail for €286. The Galaxy Watch 5 Pro will reportedly go for €420 for the Bluetooth-only model, which is slightly higher than last year.

Last but not least, the Samsung Galaxy Buds Pro wireless earbuds will reportedly start at €226. The first generation Galaxy Buds Pro wireless earbuds cost €230 back in January when they were first introduced, and it’s possible that the price will remain the same this year, although it’s too early to tell.

Samsung products to get more expensive, but chances are, you’ll still upgrade

Samsung Unpacked 10 August 2022 teaser start date time Source: Samsung

Nobody likes price hikes, but let’s face it, fans will still be fans, and they’ll happily shell out more for marginal improvements. This year’s Galaxy Z series might be a tough sell to many people, but we can already see a massive online queue wanting to upgrade. While this year’s changes will be rather small, there will be significant improvements to the durability and design of the new Z series of devices, and we can see fans shelling out a lot of money to get a better device.

If you fall into the latter category, we won’t judge; after all, people like myself who bought into the Samsung upgrade program also signed up for a reason: to experience the latest and the greatest whenever available. Those stuck on carrier deals will be able to look into upgrading early, although they’ll likely have to pay an extra fee to do so, yet many will consider it as an alternative method. People will also trade-in their existing devices and pay up a few hundred dollars to upgrade to some of these new smartphones and smartwatches.

We expect Samsung and all major carriers to offer some exclusive and appealing bundles, discounts and trade-in deals to make the upcoming Galaxy Z Fold 4 and Z Flip 4 devices more affordable. If the past is anything to go by, we’ll expect a case, a fast charger, and possibly an S Pen included with all Galaxy Z Fold 4, while we would be happy to see a case and a fast charger with all Z Flip 4 smartphones.
