Here is an article on my website that you must read, its about the Best 18 Smartwatches For Small Wrists & Women In 2023!

Let’s dive right into it.

Rhythm 24 vs Rhythm+ vs Polar OH1: Design

Let’s start this Rhythm 24 vs Rhythm+ vs Polar OH1 comparison with the Design because it’s surely one of the most important aspects of any Heart-rate Monitor.

Rhythm 24 by Scosche is the high-end Heart-rate Monitor by Scosche that comes with more premium finishing and Design. The Heart-rate Monitor has LEDs on the top, which indicates the battery life. Also, the strap of the Heart-rate Monitor has a premium finishing.

On top of that, Rhythm 24 comes with IP68 Waterproof Rating, which means you can submerge the water up to 1.5 meters.

Rhythm+ by Scosche is an affordable option, and the company has surely cut some corners here and there. The overall body of the Rhythm+ is simple and clean. The strap is perforated, which allows the airflow. Also, the Rhythm+ Design is IP67 waterproof, which means that you can submerge it up to 1 meter in water.

Polar OH1 is an advanced Heart-rate Monitor that comes with top of the line features and build quality. Polar OH1 comes with a very slim design that has a glossy finish.

The Tracker comes with an elastic strap that allows you to easily put it around your Arm. Also, when it comes to water resistance, the Polar OH1 can handle the water up to 30 meters.

As you can see, all three trackers come with amazing Design and great Build Quality. However, if I have to pick one Tracker in terms of Design, it would be Polar OH1 because of its compact and water-resistant Design.

Rhythm 24 vs Rhythm+ vs Polar OH1: Connection

When it comes to Heart-rate Monitors, the connection is very important because the monitors will pass the collected data to your Smartphone.

Rhythm 24 comes with a low Energy Bluetooth connection, which allows the Monitor to easily connect with any smartphone. Also, it comes with an ANT+ connection, which allows the Monitor to connect with compatible gym equipment and provides accurate monitoring.

Like Rhythm 24, Rhythm+ comes with Bluetooth & ANT+ connections, which means that you can easily connect it with modern smartphones and supported GYM Equipment.

Polar OH1 also comes with Bluetooth & ANT+ connections like the rest of the Heart-rate Monitors out there. As you can see, the overall connection type is similar to all three Heart-rate Monitors, and you can’t go wrong with any of them!

Rhythm 24 vs Rhythm+ vs Polar OH1: Battery Life

Battery Life is an area where many Heart-rate Monitors struggles. As Heart-rate Monitors come in a very compact size, it’s very challenging for the companies to put the bigger battery in them.

When it comes to Rhythm 24, the heart-rate Monitor comes with 24 hours of battery life, which is surely great. It also comes with the LEDs on the top, which let you know about the current battery level.

When it comes to Rhythm+, it comes with a smaller battery, which offers only 8 hours of battery life. It’s also missing the LEDs on the top, which could have been a great addition but considering the price tag, it’s understandable that the company had to cut some corners.

Polar OH1 comes with the 45 mAh lithium polymer battery, which is a high-quality battery. However, it offers a battery life of only 12 hours, which is still remarkable, considering the Heart-rate Monitor’s size.

The overall battery life of these Heart-rate Monitors is impressive, but if you want a heart-rate Monitor with the longest battery life, you should pick the Rhythm 24, which offers a whopping 24 hours of battery life, which you won’t get in many heart-rate monitors out there.

Rhythm 24 vs Rhythm+ vs Polar OH1: Performance

Now let’s talk about these Heart-rate Monitors’ performance, which I experienced during my time with these trackers.

Rhythm 24 is the premium Heart-Rate Monitor, and it is equipped with advanced optical heart-rate monitors that accurately track your Heart-rate. The best thing about rhythm 24 is that it works well with all skin tones, which is pretty remarkable.

When it comes to accuracy, the heart-rate was pretty accurate. The only problem with Rhythm24 is that it doesn’t have great water resistance, and it can handle water up to 1.5 meters.

Rhythm+ is an affordable option that comes with decent value for money. The Monitor is equipped with Patented Optical Sensor Technology, which accurately tracks the heart-rate.

It also comes with a Green/Yellow optical sensor, which is superior to a conventional Green Sensor and offers much better accuracy. When it comes to accuracy, there are no complaints here, and in my opinion, Rhythm+ is a pretty accurate heart-rate monitor.

The two of the biggest problems with Rhythm+ are the Battery Life + Water Resistance. The Monitor offers only 8 hours of battery life, and it’s water-resistant up to 1 meter only.

Polar OH1 is arguably one of the most popular Heart-rate Monitors out there, and it comes with all the bells and whistles you can expect from a great heart-rate Monitors.

The Monitor quickly connects with the smartphone via Bluetooth, and I had no problem with the integration. Also, when it comes to accuracy, I found the Polar OH1 pretty accurate.

I also compared it with the Apple Watch, which has one of the most accurate heart-rate monitors, and the readings were similar.

Another thing which I like the most about Polar OH1 is its water-resistance as the Monitor can handle the water up to 30 meters, which makes it an ideal option for swimmers. The battery life of Polar OH1 is not as good as Rhythm 24, but it’s respectable.

Rhythm 24 vs Rhythm+ vs Polar OH1: Price

Now that you know about the performance of all these trackers, let’s have a look at the price. Rhythm 24 is a premium Heart-rate Monitor, and you can get it for $99.99.

Rhythm+ is a more affordable option, and you can get it for $79.99. Polar OH has a similar price tag as the Rhythm+, and you can get it for $79.95.

In my opinion, Polar OH1 offers better value for money as compared to other trackers, so Polar OH1 is the clear winner here.

Rhythm 24 vs Rhythm+ vs Polar OH1: Which One Is Best For Me?

Rhythm 24, Rhythm+, and Polar OH1 are three very capable Heart-rate Monitors, but if you want the best one, then you will have to look at your preference.

If you want a Heart-rate Monitor with impeccable Battery Life & Accurate Tracking, but you can compromise on water resistance, then Rhythm 24 is a solid option for you.

However, if you want a heart-rate Monitor with great tracking & solid Water-resistance performance, you should get the Polar OH1.

It comes with 12 hours of battery life, which is surely not great, but it’s respectable. Also, Polar OH1 offers the best value for money, so if you want the best Heart-rate Monitor overall, then you should consider Polar OH1.
