There are many reasons to monitor your heart rate. Chest straps are the gold-standard, but they can feel clunky and cumbersome. Over time, they can be uncomfortable. And the fit can be finicky to adjust.
Thankfully, there are lots of heart rate monitors without chest straps. Most of these are worn on the wrist, and many are part of full-featured fitness watches. A sensor on the back of the tracker presses against your skin and uses pulses of light to determine your heart rate.
While we review a few that only track heart rate, many also perform double-duty by monitoring steps, sleep, and various fitness goals. Some, like the Apple Watch, blend in with your phone for a unique experience. Others, like Garmin’s GPS watches, can be used for walking, running, and cycling.
Below we’ve provided a collection of excellent heart rate monitors without chest straps.
Let’s get started!

FAQ and Buyer’s Guide
How Accurate are Wrist-Based Heart Rate Monitors?
Strictly speaking, wrist-based heart rate monitors are usually not as perfectly accurate as monitors with a chest strap. This is because they measure your pulse from the blood flow in your wrist. A few models also monitor electrical signals, though most use the former method of monitoring.
Wrist-based heart rate monitors can often slip to become off by a few beats per minute, particularly if you rapidly change activity levels. However, this only truly matters if you are aiming for a workout with an especially narrow heart rate target. For all other uses, wrist-based monitors should be fine.
How Tight Should I Wear a Wrist-Based Heart Rate Monitor?
When wearing a wrist-based heart rate monitor, you don’t want to make things too tight as this can close off blood flow and provide inaccurate readings. Instead, wear your heart rate monitor about 2 fingers’ widths above your wrist bone.
In terms of tightness, make sure that the sensor itself is in contact with your skin but that it doesn’t feel uncomfortable. It shouldn’t move around on your wrist, but it also shouldn’t be so tight it leaves deep marks when you take it off.
How Do They Work?
Most wrist-based heart rate monitors work by shining lights onto your wrist, where they measure the changes in blood volume from your blood vessels. In this way, they can estimate changes in your heartbeat.
Does it Matter Which Wrist I Wear it On?
You might find slight changes in reported heart rate depending on which wrist you wear your monitor on. But these are not usually very noticeable. Generally, it doesn’t matter; use whichever wrist is most comfortable for you.
Which is Better: Wrist Heart Rate or Chest Band?
It depends on what you need. Wrist-based heart rate monitors are better for general comfort and for accompanying you on daily exercise activities.
However, chest band monitors will provide more precise measurements of your heart rate and may be more valuable to dedicated exercisers or those with serious heart conditions.
