Bryan Johnson's Wearable and Smart Scale: Oura, Whoop and Withings (2026)

In the "Stuff you may want" list of his January 2026 protocol, the wearable line reads: "Apple, Oura, Whoop, Garmin, they're all great." He does not name a single brand as essential. His sleep section says to track your habits "with a journal or sleep tracker," and mentions his wearable reporting eight months of perfect sleep.

His protocol calls lowering resting heart rate before bed "the single most effective thing you can do for your health," and says that when it is low, sleep is better. He says that finishing eating around noon gets his to about 39 beats per minute before bed. Any of the wearables he lists reports resting heart rate overnight, so pick the one you will actually wear every night.

An Oura Ring ($349 on Amazon when we checked in October 2026) is the easiest to sleep in, but most of its insights need a monthly Oura membership. An Apple Watch or Garmin you already own works too, by his own list. Whoop is subscription-only and not sold as a standalone Amazon product, so we don't list it.

Right after waking, his daily routine lists a "body composition measurement: weight, fat, muscle, hydration, arterial stiffness." The protocol does not name the device. A smart scale like the Withings Body Comp ($229.95) covers most of that list: Withings says it measures fat, muscle, bone and water mass, visceral fat, "Vascular Age" and nerve health. That is our match to his list, not a brand he names.

•Oura Ring 4: $349 plus a membership. It tracks sleep and resting heart rate overnight from your finger.•Apple Watch or Garmin: He lists both as fine. They make sense if you already own one.•Withings Body Comp: $229.95. It covers the morning weight, fat, muscle, hydration and vascular check. Prices are Amazon prices we checked in October 2026 and change often.

His protocol names wearable brands but no scale, and gives no accuracy comparison between devices. Consumer scales estimate body composition and are less precise than clinical scans. Use any device for trends over time rather than single readings.
