watchOS 4 introduces an expanded Heart Rate app that's able to track your current heart rate, your resting heart rate, average heart rate while walking, and your recovery rate after exercising, providing more information about your overall health. It's also able to send alerts if it detects a heart rate above 120 when you're not exercising.
These features are available on the new Apple Watch Series 3 models and the Apple Watch Series 2 and Series 1 models that were introduced in 2016, but some of the features are not available original Apple Watch models sold in 2015.
As Twitter users discovered after downloading watchOS 4 earlier this week, the original Apple Watch is only able to display current heart rate with a much simpler interface for the heart rate app, with no sign of resting heart rate or average walking heart rate. The app does offer the heart rate graph with a tap on the display, though.
It's not entirely clear why the original Apple Watch doesn't offer the full range of heart rate features, but it may be due to hardware limitations. The first Apple Watch offers an original S1 processor, which has since been significantly upgraded in Series 1, Series 2, and Series 3 updates, and its battery life is not as robust.
Apple discontinued the original Apple Watch in 2016 when the Series 2 was introduced, replacing it with the Series 1 Apple Watch. The Series 1 model is similar to the original Apple Watch, but features an upgraded S1P processor. The Series 2 Apple Watch uses an S2 processor, and the Series 3 Apple Watch uses an S3 processor.

Last year, Apple launched CarPlay Ultra, the long-awaited next-generation version of its CarPlay software system for vehicles. Nearly nine months later, CarPlay Ultra is still limited to Aston Martin's latest luxury vehicles, but that should change fairly soon.
In May 2025, Apple said many other vehicle brands planned to offer CarPlay Ultra, including Hyundai, Kia, and Genesis.

Apple recently updated its online store with a new ordering process for Macs, including the MacBook Air, MacBook Pro, iMac, Mac mini, Mac Studio, and Mac Pro.
There used to be a handful of standard configurations available for each Mac, but now you must configure a Mac entirely from scratch on a feature-by-feature basis. In other words, ordering a new Mac now works much like ordering an...
Ugh Apple, seriously? I’m an owner of the stainless steel 1st gen Apple Watch and I’m not looking for an upgrade yet since it’s in a pretty good condition. Why should my watch not get the watchOS 4 features if my watch’s hardware is practically identical to Apple Watch Series 1 except for the faster processor. Ridiculous!
I would rather have Apple remove other useless features like ToyStory Watch faces and let me use a feature that I was actually looking forward to.

A faster more efficient processor makes a huge difference. I wouldn’t call that “practically the same”.
It’s not where I’m getting at. It’s a very capable device which is why it annoys me that it gets undercut. There is no reason for them to do that except for forcing the customer to upgrade.
Wouldn't leaving it off of watchOS 4 entirely be an even better way to "force the customer to upgrade"?
Yeah, so click that UI element right there and you’ll get the expanded graph. I have an OG Watch and it shows the graph. The only thing missing is the resting heart rate.
Same thing here. I also have the original Apple Watch and it seems to show the graph. See below....
