Despite testing smartwatches for a living and spending my days working for Tom’s Guide, like most people, I only use around 10% of the features on the tech I wear. Yet recently, I realized that the iPhone in my pocket measures more than I realized. One key metric you can measure is stability; when I got my results, I was shocked to find that, despite being six weeks into my sixth marathon training plan, my overall stability isn’t great.
If, like me, you’re an iPhone user, it’s easy to check out your stability score. The measurement, which you can see in the Health app, gives you a better understanding of your overall mobility.
