The WHOOP Peak 5.0 Sensor, a screenless tracker you read in the WHOOP app, works with Android phones and iPhones, gives daily recovery and strain scores and is lighter to wear all day, though it needs a WHOOP membership, while the Google Pixel Watch 4, a smartwatch with a 1.2-inch OLED screen, takes ECG heart-rhythm readings, has built-in GPS for runs without your phone and is swimproof to 50 m.
