AliveCor already makes smartphone cases with built-in ECG monitors, and while using it helps monitor heart health and warn of any immediate dangers, it makes more sense for the sensors to be placed on a smartwatch — it’s more convenient, and a lot more discrete. AliveCor agrees, and has announced the Kardia Band, a medical standard ECG monitor for the Apple Watch.

It replaces the strap currently fitted to your watch, and as such can be swapped out for another at anytime, so there’s no need to sacrifice style for function when the situation calls for something a little flashier. You only need to place a finger against the sensors in the strap to get a reading, which is recorded to a new Kardia Mobile app in real-time.

Getting instant ECG readings is important for people with chronic heart problems, in particular something called atrial fibrillation, or AF, which the Kardia Band’s software specifically detects. Why? Apparently, it’s one of the leading causes of strokes. Recognizing the presence of AF helps people make the decision to get medical care. The Kardia Band’s data can be helpful to doctors, and using the app on the Watch lets you record voice memos to note circumstances around the readings.

Kardia Mobile syncs with Apple’s HealthKit to include ECG data with other fitness and health metrics collected by the platform, building a more detailed picture of your wellbeing over time. The strap is made for the Apple Watch while the app is compatible with iOS, it’s also out for Android, where it works with AliveCor’s ECG readers in phone cases. The Kardia Band will go on sale in the next few months, and while there’s no confirmed price yet, the company says some features will require a subscription to unlock.

This Apple Watch tech might make your iPhone better

According to Korea's The Elec (via MacRumors), LTPO3 display technology, which was first utilized in the Apple Watch Series 10, may also be adapted for future iPhones. This new technology improves both power efficiency and display performance.

On the flagship Apple Watch Series 10, LTPO3 enables Apple to optimize each pixel to emit more light at wider angles and improve battery efficiency.  As a result, the display is 40% brighter than on the previous model, the Apple Watch Series 9, which employed LTPO2. The newer technology also allows for a faster refresh rate when the watch is in always-on mode.

Telsa may be making an official app for the Apple Watch

Whether you're a Tesla fan or not, we can all agree that the cars have some seriously cool features. Your iPhone can function as a car key and you can use it to unlock your doors. That's been a feature for years, but there hasn't been an official Apple Watch app (although third-party solutions do exist and work well.)

According to MacRumors, that might be about to change. The Tesla iPhone app was updated recently for iOS 18, but one person spotted references to an upcoming Apple Watch version of the app. The code makes it look like you'll be able to use your Apple Watch as a digital key to unlock your Tesla, assuming it's compatible.

I wore the titanium and aluminum Apple Watch Series 10. This is the one I would buy
A person wearing the titanium Apple Watch Series 10.

For the last few weeks, I’ve worn the latest Apple Watch Series 10 in titanium to find out if it’s the first smartwatch to take me away from only wanting to wear my various quartz and mechanical watches. I wanted to find out if paying more for the titanium version would help it give me that same warm feeling, like meeting up with a good old friend, I get when I put on one of my other favorite watches.

I thought I had the answer quickly, but then things were complicated when the aluminum Series 10 arrived for me to try. It changed my opinion, but was it enough to make me want to return the titanium smartwatch?
It’s not just about the titanium
