Apple's next big thing

Dear Tim letters

When the Apple Watch was originally released in 2015, it was pitched as a great watch, an intimate way to communicate, and a comprehensive fitness device. While the original Apple Watch (later renamed Series 0) lacked GPS and was generally a slow device, it has shown dramatic improvements year over year particularly for Apple’s health initiatives.

When Apple released the Series 1 and Series 2 Apple Watches, it added heart rate monitoring for Apple Health. When you enable heart rate monitoring, you  can also turn on heart rate notifications, so you know if your heart rate remains above or below a chosen beats per minute (BPM), or to occasionally check for an irregular heart rhythm. Irregular rhythm notifications are available only with watchOS 5.1.2 or later in certain countries.

With Apple Watch Series 4, Apple added a electrocardiogram monitoring (also known as ECG and EKG). The ECG app on Apple Watch (Series 4 or newer) can record your heartbeat and rhythm using the electrical heart sensor and then check the reading for atrial fibrillation (AFib). It then records that information into the Apple Health app.

Since the release of Apple Watch, there have been countless stories of people’s lives being saved by the health advancements in Apple Watch and Apple’s Health initiatives.

Apple Watch ECG

If you have an Apple Watch Series 4 or newer, here’s a how to guide on how to take an ECG.

Apple also includes a Health app on the iPhone where it easy to learn about your health and start reaching your goals. It consolidates data from iPhone, Apple Watch, and third-party apps in one place.

Feature Request: Apple Watch sleep tracking needs an overhaul, as Garmin adds naps

Apple Watch sleep tracking | Cat asleep on a desk

Apple Watch sleep tracking is the reason I decided to hold onto my old Series 4 model when I bought a Series 5. It was worth so little that I figured I’d hang onto it and simply swap watches when I got into bed to use the S4 as a dedicated sleep tracker.

Monitoring my reported sleep patterns in the Health app, however, has revealed that the Apple Watch isn’t actually very good at the finer details – like telling when I’m in bed, when I’m asleep, and when I’m asleep in bed …
