Scosche Rhythm24 ($100)

The most impressive heart-rate monitor we’ve worn in a while, the Rhythm24 uses Valencell technology—the gold standard in optical pulse tracking. The elastic band is comfortable, low profile, and waterproof, so it can monitor your heart rate while you swim, storing the data in onboard memory and then syncing it to your phone or watch later. It also measures heart-rate variability, a feat most devices in this class can’t perform.

The Venu is an ultra-sporty smartwatch. It tracks everything from running and swimming to Pilates and yoga. The Amoled screen displays workouts, illustrating each move with an animation. There’s also music storage and even incident detection, which directs a paired phone to dial an emergency contact in the event of a crash.
Omron Healthcare HeartGuide ($499)

According to the Centers for Disease Control and Prevention, nearly one in three American adults have hypertension. Enter the HeartGuide, the first FDA-cleared watch that accurately monitors blood pressure. Underneath the standard watchband is an inflatable cuff like the one your doctor uses.
