Disclaimer

I’m not a doctor, registered dietitian, technology or fitness expert. The purpose of my blog is to share my experiences with technology, food, fitness, and life — not to dole out random advice. All opinions expressed on this site are solely my own.

This is not medical or health advice

This site reviews fitness trackers and other health-tracking devices, and the reviews talk about heart rate, heart rate variability, sleep, blood oxygen, recovery, and calories. What I write about those numbers is my personal opinion and experience. It is not medical advice or health advice, it is not a diagnosis of anything, and it is not a substitute for care from someone qualified to give it.

These are consumer products, not medical devices

The devices reviewed here are consumer products. They are not medical devices, and their measurements are not diagnostic. As several of my reviews show, they can be wrong, sometimes by a lot. A reading from a watch or a wristband cannot tell you whether something is wrong with your heart, your sleep, or your health, and a normal-looking reading does not mean everything is fine.

Talk to a professional first

Before you act on anything health-related that you read here, talk to a doctor or another qualified healthcare professional. This matters most for heart rate, sleep, recovery, and training decisions. Don’t start, stop, or change a training plan, a medication, or a treatment because of a tracker score or because of something I wrote. If a device shows you something that worries you, or you don’t feel right, get it checked by a professional instead of relying on the device. If you think you are having a medical emergency, call 911 or your local emergency number.

Information changes

Reviews describe devices and software as they were when I tested them, and manufacturers change both through updates. Medical research moves on too, and nothing here is guaranteed to reflect the most recent findings. The use of any information provided on this site is solely at your own risk.
