Figuring out if you have diabetes could soon be as easy as strapping on an Apple Watch.

A new study from Cardiogram shows that by using heart rate monitors on wearables like the Apple Watch, neural networks can now detect whether the wearer shows early signs of diabetes with astonishing accuracy.

If you’ve considering buying a shiny new Apple Watch Series 2, you might be wondering if it can really help you to get in shape. Especially if you’ve seen the recent headlines claiming that fitness trackers don’t work.

So what does science really have to say about wearables? I decided to investigate the science behind Apple Watch fitness assumptions.

We’ve seen Wednesday’s Apple keynote dissected every which way, but how about analyzing the moments where viewers’ heart rates jumped at the latest news from the Good Ship Cupertino?

That’s what the developers and beta testers of heart-monitoring Apple Watch app Cardiogram did, as they set their devices to workout mode for the anticipated event to find out what really tugged at their heart strings.

The results are … interesting.
