🌟 Hello on a bright and shiny Thursday, friend! Let’s start with a little throwback trivia. What was the most downloaded app of the 2010s? Was it … A.) Twitter, B.) Skype, C.) Facebook or D.) Candy Crush? Before you peek at the answer at the end, say your best guess out loud right now.

Are you ghosting me? Stop that! Don’t miss out on the security alerts, tips and fun I post on social media. If you’re not following me already, hit these links for Instagram, X, YouTube and Facebook, and say, “I go Komando!” Yeah, I know what that means. 😉 — Kim

Sensors in today's smartwatches can detect your heartbeat, track how you sleep and even monitor blood oxygen levels. We’re not far from your watch tracking your blood sugar ... and possibly sending reports about it to your doctor.

Ever wondered, "Just how accurate are these smartwatch readings?" You're not the only one, so I took a look. Smartwatches and fitness watches have some serious flaws you should know about.

Paging Dr. Watch! Emergency!

Turns out that cramming a bunch of sensors into a tiny watch doesn't create the most legitimate results. Who knew? If you're seeing spikes or drops in readings for sleep states or blood oxygen levels, don't panic — it happens to everyone.

• Sensors have problems with skin tone: A lawsuit filed against Apple says its Watch blood oxygen sensors don't work correctly on dark skin. Yikes! Research, however, indicates this may be a problem with many blood oxygen sensors.
• Smartwatches don’t reach medical levels of accuracy: High-grade studies are limited, but this one for Garmin fitness watches found they couldn’t measure energy expenditure or blood oxygen levels with enough accuracy to make medical decisions.
• Step counters and calorie trackers are easily fooled: Smartwatches stink at measuring calories burned and can struggle to define steps walked. And don't get me started on how vague sleep tracking can be!

OK, so smartwatches are only helpful for estimates. But what can we do to make them better?

Take your health in stride

Here are a few figurative steps I think all smartwatch users should take while getting in their literal steps (plus, a free play on words!).

• Size your watch for your wrist: Many accuracy problems are caused by loose-fitting watches that slip around on your arm. Buy one with straps you can adjust.
• Focus more on heart rate than steps or calories: Your pulse is right there, so it's no surprise watches are more accurate about heart rate than almost anything else.
• Don’t stress over readings: Ironically, that stress will increase your heart rate and other vitals. Even worrying about sleep tracking can cause inadequate sleep (doctors call it “orthosomnia”). Don't think of readings as hard numbers but rather general brushstrokes about your health picture.
• Watch readings over time: Those bigger-picture charts and graphs are more helpful than going number by number.
• Visit a doctor if you’re worried: Don't waste time or energy obsessing over what your smartwatch tells you. If you've got a serious concern, make an appointment like a grown‑up.

‘Kim, which watch should I buy?’

This is one case where splurging on newer tech is actually better; the big-name smartwatches get more accurate with each new model. Here are the heavy hitters:

• Use an iPhone? The Apple Watch Series 10 has all the bells and whistles, including ECG, fall detection and heart tracking. For a cheaper option, the 2nd-gen Apple Watch SE is under $200 right now.
• In the Google-sphere? The Pixel Watch 3 is Google’s fancy-schmancy version — and way more affordable than Apple’s. For something more fitness-focused, a Fitbit is the way to go.
• If your phone’s a Samsung: You might as well get the watch that “talks” to your phone best — the Galaxy Watch 7 is Samsung’s latest and greatest.
• In it for health and wellness? I hear great things about WHOOP.

⌚ Having a smartwatch is really great. On one hand, you have something you can use to answer texts and stuff; on the other hand, you don't.

🚨 eBay scam alert: People are buying high-ticket items on eBay, filing returns, then sending back thank-you cards instead of products. Sellers report the scam (with proof, but the return label is on a tiny envelope) and get stuck in an endless appeals process. Find another place to sell your expensive stuff.

🧬 Book ‘em, Danno: A 65-year-old Massachusetts suspect was arrested for a 1988 crime after police collected his spit from the sidewalk. They matched his saliva to DNA found under the victim’s fingernails, a bloody T-shirt and a cigarette left at the crime scene. The victim was a 25-year-old Boston woman with a toddler at home.

This Zoom feature isn’t even remotely funny: Zoom’s new AI companion takes notes, summarizes meetings and even tells you who talked most. Click the magic wand icon below the main video window to use it. You can ask it for a quick update or to pull out action items from the discussion, too. Fine print: Available for paid plans only.

Six in 10 companies are firing Gen Z workers — often, just months after hiring them fresh out of college. They claim Gen Zers are struggling with communication, professionalism and motivation. Their ex-bosses also say they constantly need direction and have trouble showing up to work.

👋 Don’t fall for this: There’s a new viral post making the rounds on Facebook, Instagram and other Meta platforms. The post says if you don’t copy the post and share it, you’re fine with Meta using your info and photos. Reality check: It’s fake and won’t do diddly-squat. Make your account private; Meta AI (supposedly) only pulls from public posts.

💸 The next big thing? Former Apple designer Jony Ive and OpenAI’s Sam Altman are working on an AI-powered device. Details are scarce (of course!), but they say it’ll handle advanced tasks like booking travel and identifying plants from photos, with more power than the average smartphone and fewer disruptions than a standard phone.

The nerve: After boarding the plane for a flight to Miami, there was a mechanical issue, so passengers left the plane to stretch their legs. When one guy returned, someone told him a blonde woman stopped at his seat, unplugged his charger and put it in her bag. He confronted her, camera in hand. Here’s the vid.

📊 Secret you need to know: If you use Google Docs or Microsoft OneDrive, you can go back in time to see earlier versions of your work (or someone else’s). In Google Docs, head to File > Version History > See Version History. In OneDrive, it’s under File > Info > Version History. Bonus tip: If you want to know who does what in real time in a Google Doc, turn on the Track Changes option.

Alexa, enough already: Set up commands that do more on your Amazon Echo. In the Alexa app, tap More (bottom right corner) > Routines. Tap the + (plus sign), then choose your trigger (time of day or command) and what happens. For “go to bed,” you could include shutting off the lights, starting your white noise and locking your smart doorknob. Sweet!

🧼 Your photos are a mess: Find what you want with AI-powered albums. On a Mac, open Apple Photos and choose File > New Smart Album. Pick what you want (like photos of the beach) and it’ll pull in pics that match. In Google Photos for the web, go to Albums > Create Album. Here, you can choose the people and/or pets you want to include.

You can’t see me: An SSID is your network’s unique identifier. Hide it so randos don’t see your Wi‑Fi network when they’re scanning for nearby options. To do this, go into your router’s settings, look for Wireless Settings, and tap Disable SSID broadcast. “Kim, how the heck do I access the settings?” Go to No. 1 here.

🎉 Many retail websites don’t have static pricing: Depending on the time or day of the week, you might beat the algorithm and score a better deal. Your best bet for a bargain is early in the week or at off-peak hours (think late at night or early in the morning). Whoa, this tip alone is worth the price of this newsletter. Oh, wait — it’s free!

It’s not the holidays without a Hallmark movie or five … And here’s a link so you can print this list out if you want.

The answer: C.) Facebook. The others were popular for sure, but Facebook was king of the social media castle, with 4.5 billion downloads.
