Rhythm 24 vs Rhythm+ vs Polar OH1 Review: Detailed Comparison

Nothing beats dedicated Heart-rate Monitors for accurate Heart-rate Monitoring because they are built to track your Heart-rate.

This guide is for you if you are an athlete or want reliable heart-rate monitoring.

In this Rhythm 24 vs. Rhythm+ vs. Polar OH1 comparison, I will compare these three common Heart-rate Monitors and advise you on which one is ideal for you.

Let’s get started straight now.

Rhythm 24 vs. Rhythm+ vs. Polar OH1: Which Is Better?

Let’s begin this Rhythm 24 vs. Rhythm+ vs. Polar OH1 comparison with the design, as it’s unquestionably one of the essential parts of any Heart-rate Monitor.

Scosche’s Rhythm 24 is a high-end Heart-rate Monitor that features superior finishing and design. The top of the Heart-rate Monitor contains LEDs that indicate the battery life. In addition, the Heart-rate Monitor’s strap boasts a high-quality finish.

Furthermore, the Rhythm 24 has an IP68 waterproof Rating, which means it may be submerged in water for up to 1.5 meters.

Scosche’s Rhythm+ is a low-cost choice, and the company has undoubtedly cut some corners here and there. The Rhythm+‘s general body is basic and sleek. The strap is perforated, allowing for airflow. Furthermore, the Rhythm+ Design is IP67 waterproof, which means it may be submerged in water for up to 1 meter.

Polar OH1 is a cutting-edge Heart-rate Monitor with top-of-the-line features and build quality. Polar OH1 has a relatively thin design with a shiny finish.

The Tracker comes with an elastic band that makes it simple to wrap over your arm. The Polar OH1 can withstand depths of up to 30 meters in terms of water resistance.

As you can see, all three trackers have fantastic design and build quality. However, if I had to choose one Tracker based on design, it would be the Polar OH1 because of its small and water-resistant design.

When it comes to Heart-rate Monitors, the connection is critical because the monitors will send the data collected to your smartphone.

Rhythm 24 includes a low-energy Bluetooth connection that allows the Monitor to connect to any smartphone. It also has an ANT+ connection, which allows it to connect to compatible gym equipment and provide accurate monitoring.

Rhythm+, like Rhythm 24, has Bluetooth and ANT+ connectivity, allowing you to link it to modern smartphones and approved GYM equipment effortlessly.

Like the rest of the Heart-rate Monitors on the market, the Polar OH1 has Bluetooth and ANT+ connectivity. As you can see, the overall connection type is the same for all three Heart-rate Monitors, and there isn’t a single one that isn’t a good choice!

Battery Life

Many Heart-rate Monitors have issues with battery life. Because Heart-rate Monitors are so small, it’s difficult for manufacturers to fit a larger battery in them.

When it comes to Rhythm 24, the heart-rate Monitor has a battery life of 24 hours, unquestionably excellent. It also includes top-mounted LEDs that display the current battery level.

The Rhythm+ has a smaller battery that only provides 8 hours of battery life when it comes to the Rhythm+. It also lacks the top LEDs, which may have been a nice feature, but given the price tag, it’s understood that the business had to cut some corners.

The Polar OH1 comes with a 45 mAh lithium polymer battery, which is good quality. However, the battery life is only 12 hours, which is still impressive given the size of the Heart-rate Monitor.

The general battery life of these Heart-rate Monitors is amazing. Still, if you want the longest battery life, you should choose the Rhythm 24, which delivers a massive 24 hours of battery life, which you won’t find in many heart-rate monitors on the market.


Now, let’s discuss the performance of these Heart-rate Monitors that I experienced when using these trackers.

Rhythm 24 is a premium heart rate monitor with innovative optical heart-rate monitors that precisely track your heart rate. The nicest thing about rhythm 24 is that it works with all skin tones, which is impressive.


When it came to accuracy, the heart-rate monitor did a good job. The only issue with Rhythm24 is that it does not have a high level of water resistance, and it can only tolerate water up to 1.5 meters deep.

Rhythm+ is a low-cost solution that provides good value for money. The Monitor features Patented Optical Sensor Technology, which precisely records heart rate.

It also includes a Green/Yellow optical sensor, which outperforms a normal Green Sensor in terms of accuracy. There are no concerns about accuracy, and Rhythm+ is a fairly accurate heart-rate monitor in my perspective.

The battery life and water resistance are two of the most serious issues with Rhythm+. The Monitor has an 8-hour battery life and is only water-resistant to 1 meter.

The Polar OH1 is undoubtedly one of the most popular Heart-rate Monitors on the market, and it includes all of the bells and whistles you’d expect from a solid heart-rate Monitor.

The Monitor rapidly connects to the smartphone via Bluetooth, and the integration was flawless. I found the Polar OH1 to be quite good in terms of accuracy.

I also compared it to the Apple Watch, which has one of the most precise heart-rate monitors, and the results were comparable.

Another feature that I appreciate about the Polar OH1 is its water resistance, as the Monitor can withstand depths of up to 30 meters, making it an excellent choice for swimmers. The battery life of the Polar OH1 is not as good as that of the Rhythm 24, but it is enough.

Polar OH1 delivers superior value for money, in my opinion, when compared to other trackers. Hence Polar OH1 is the clear winner here.

Rhythm 24 vs. Rhythm+ vs. Polar OH1: Which One is best for me?

The Rhythm 24, Rhythm+, and Polar OH1 are all capable Heart-rate Monitors, but if you want the best one, you must consider your personal preferences.

If you want a Heart-rate Monitor with excellent battery life and accurate tracking but don’t mind sacrificing water resistance, the Rhythm 24 is a good choice.

However, if you want a heart-rate monitor with excellent tracking and water resistance, the Polar OH1 is the way to go.

Rhythm 24 vs. Rhythm+ vs. Polar OH1: Which One is best for me?
