The Apple Watch is a wearable smart watch introduced by Apple in 2015 which includes a number of sensors useful for doing personal science. Since the first release, Apple Watches include a heart rate sensor and accelerometers/gyroscopes for [[activity tracking]]. Since 2020, some Apple Watch models also do rudimentary [[sleep tracking]], though the capabilities are still somewhat behind other wearables. Since the 4th generation, Apple Watches also include an [[ECG]] sensor that can be used to take manual readings and since the 6th generation they it includes a [[Oxygen saturation|Blood oxygen]] sensor. Beyond this, the Apple Watch also uses its microphone to regularly record environmental noise levels.

Since the 4th generation, Apple Watches also include an [[ECG]] sensor that can be used to take manual readings and since the 6th generation they it includes a [[Oxygen saturation|Blood oxygen]] sensor, though this has been disabled in recent models sold in the USA due to patent issues<ref>https://www.theverge.com/2024/1/17/24041945/apple-watch-series-9-ultra-2-blood-oxygen-ban</ref>.

Beyond this, the Apple Watch also uses its microphone to regularly record environmental noise levels.
