New Study Shows Smartwatch Stress Sensors Have No Idea What They’re Doing

Dutch researchers found that not only are stress sensors inaccurate, but they sometimes report the opposite of user experiences.

You might want to think twice before you put a lot of stock in the latest stress charts from your fitness wearable. A recent study from the Netherlands’ Leiden University, published in the Journal of Psychopathology and Clinical Science, has found that when smartwatches and similar devices record readings on stress, fatigue or sleep, they’re frequently getting it wrong.

Researchers studied 800 young adults using the same Garmin Vivosmart 4 smartwatch model. They compared the data the smartwatches produced with the reports that the users created four times per day about how sleepy or stressed they were feeling. Lead author and associate professor Eiko Fried said the correlation between the wearable data and the user-created data was, «basically zero.»

A representative for Garmin did not immediately respond to a request for comment.

Stressed or sex? Your watch doesn’t know

So why do wearables like fitness smartwatches get it so wrong? Their sensors are fairly limited in what they can do. Watches like these need to be worn correctly at all times (a loose or tight watch may give poor readings, for example), and they typically use basic information like pulse rate and movement to make guesses about health.

Those guesses don’t always reflect real-world scenarios. A wearable may identify high stress when the real cause of the change was a workout, excitement over good news, or sex. There are so many potential alternatives to stress or fatigue that the watches in the study never really got it right — and the devices sometimes guessed the complete opposite emotional state from what users recorded.

The Dutch study did note that Garmin’s Body Battery readings, which specifically measure physical fatigue, were more reliable than stress indicators, but still inaccurate. And sleep sensing performed the best of them all, with Garmin watches showing a two-thirds chance of noting the differences between a good night’s sleep and a bad one.

It’s also worth noting that smartwatch sensors can become more accurate as technology improves. It would be interesting to run a similar study with the newer Garmin Vivosmart 5 to see if anything has improved, as well as see if other models like the latest versions of the Apple Watch have similar accuracy results.

Mobile Internet Without Borders: How Verum E-SIM Is Changing the Game for Travelers and Beyond

In an era when flights take just a few hours, but data boundaries remain very real, a solution has emerged that significantly simplifies life for frequent international travelers. The Verum E-SIM app offers a next-generation virtual SIM card — no plastic, no waiting for delivery, and no traditional roaming charges.

While eSIM technology itself is no longer new, Verum takes it further: the internet works in over 150 countries worldwide under clear, uniform conditions. Connection happens through the app in just a couple of minutes — choose a package (or even a global one), pay, and activate. No need to buy local SIM cards at the airport, hunt for carrier shops, or struggle with explanations in a foreign language.

One of the biggest advantages is the complete absence of hidden fees or billing surprises. Plans are fully transparent: you immediately see how many gigabytes you get and for how long. Speed and reliability are provided by partner operators in each specific country — this isn’t a single “averaged” provider for the entire world.

Another key point for many users is that no VPN is required. As long as your device is using Verum E-SIM traffic, all familiar services and websites open directly, without extra layers or speed loss.

For those traveling with a group or family, portable Wi-Fi routers with Verum eSIM support have become a great option. One profile — and the internet is shared simultaneously across multiple smartphones, tablets, and laptops. It’s convenient on the road, in a hotel, or even in a café where the local Wi-Fi is unreliable.

Payment flexibility is also a plus: the service supports regular bank cards, cryptocurrencies, and various alternative methods — so you can choose whatever feels most convenient and cost-effective for you.

In the end, Verum E-SIM is more than just another data app. It’s a way to make mobile internet as natural and hassle-free abroad as it is at home. The difference becomes especially clear when you compare a roaming bill from one of the major operators with your Verum expenses after two or three trips.

The technology is still gaining popularity, but many travelers are already saying: “For the first time in ages, internet abroad stopped being a source of stress.” Solutions like this are shaping the future of mobile connectivity — without extra cables, borders, or unpleasant surprises.

If you travel often or simply value stable internet without unnecessary hassle — it’s worth giving it a try at least once.

Google Agrees to Pay $135M in Huge Android Data-Harvesting Settlement

Google’s settlement with Android users would resolve the lawsuit and alter how the company manages its terms of service, though not all users would receive financial compensation.

Android users, take note: On Tuesday, Google reached a preliminary settlement in a class action lawsuit over illegal data collection. If it goes through, Google will pay out $135 million to Android phone users, possibly the largest settlement of this kind in history.

According to the lawsuit, starting in 2017, Google programmed its Android OS to automatically collect cellular data via carriers, with no way for users to opt out. The lawsuit asserted that this data collection occurred even when users took steps such as disabling location tracking or closing apps.

The lawsuit also made a significant claim: that Google’s data collection practices constituted a crime called conversion. Conversion occurs when one party takes property from another with the intent to deprive them of it. No conversion cases have ever settled for $135 million.

As part of the settlement, Google has denied any wrongdoing.

«We are pleased to resolve this case, which mischaracterized standard industry practices that keep Android safe. We’re providing additional disclosures to give people more information about how our services work,» said Google spokesperson José Castañeda.

The lawsuit could have significant implications for data privacy and other data collection practices. It will also change Google’s terms of service. The company has agreed to obtain more explicit consent from Android users when first using new phones, to include a toggle button to turn off certain types of data collection, and to disclose data collection more clearly.

How do Android users know if they’ll get paid?

This is a preliminary settlement ahead of the first trial date in August, so we don’t yet know all the details. The judge will have to approve the settlement and confirm the time frame, payment method and other specifics.

Here’s what we do know: Payments would be capped at $100 per person, so no one should expect to get more than that. Also, in most cases, you have to sign up to become a part of a class action lawsuit. If you didn’t sign on to this specific lawsuit by now, you’re not likely to receive any money.

Another settlement involved ad targeting

It’s been an eventful week for Google settlements. Earlier this week, Google also agreed to a $68 million preliminary settlement in another class action lawsuit, this one involving Google Assistant (now being replaced with Gemini for Home).

Users said smart devices used Google Assistant to listen to them without their activation, leading to ad targeting based on information they hadn’t willingly shared.

In that settlement, payments will be made automatically. No claim form is required to receive a payment.
