Scosche RYTHM +

RHYTHM+ fits comfortably on your forearm and communicates with a variety of HR display-quipped devices.

There are dozens of great fitness apps available for your smartphone. But most of them are only as good as the info you enter. The more information you give your fitness apps to work with, the better they'll work for you. Scosche's RHYTHM+ is the just the tool you need. This versatile arm-mounted device tracks your heart rate and automatically relays the info to some of the most popular fitness apps, like DigiFit, Runkeeper, MapMyFitness, and Strava. And Scoshe's PerformTek sensor takes accurate readings — more accurate than many leading brands.

Dual-mode processor communicates with lots of different devices

RHYTHM+ uses the Bluetooth Smart protocol to communicate with your smartphone. It'll automatically sync and upload data to your fitness app, without interfering with anything else your phone is doing. And it's ANT+ compatible. That means it'll talk with a variety of popular running watches and cycling computers, sending heart rate data to them so you don't have to pack your phone with you when you step out the door for your ride or run.

Beats the Chest Strap

Written by: ChicagoJoe from las vegas, NV on January 27, 2016

Crutchfield Customer Review (What's this?)

I was sick off the skin irritation caused by traditional chest strap Heart Rate Monitors. I use a Garmin Fenix 2 and was concerned that some of the metrics such as vertical oscillation and cadence may not be measured with the Scosche, however that is not the case and all metrics measured with the traditional chest strap appeared to be measured with the Scosche.

Pros: Forearm use is convenient and easy to use.

Cons: Daily charging as opposed to long term battery.

Crutchfield Customer Review (What's this?)

Works great with my iPhone for spinning



Awesome! Wish it had more config on iPhone

Written by: MicMc from Texas on October 18, 2015

It was here quick, installed great, and was working the same night. I'm really happy to not have my phone turned on anymore. I would love to see the configurations in the iPhone that are available in Android, but I understand that takes some time. Despite that, I'm really happy with the sleep monitor, and with the band itself. Caution: For those with overly large wrists, you "can" stretch the band to fit. I have a US size 8 wrist and was able to make it fit. It is snug, but has never come off and doesn't leave a mark.

Pros: Great sleep monitoring, great wakeup alarms. Love not having audible alarms anymore. (I bought 5 of them for the 5 adults in the house) I can also shower with it and have not had any issue.

Cons: Would like more configuration of colors and vibrations in the native app but the cost of this guy is amazing for the quality.

Fantastic Heart Rate Monitor

Written by: JBA from Texas on April 12, 2015

Crutchfield Customer Review (What's this?)

We love this heart rate monitor! We have used the other heart rate monitors with the chest strap and the chest strap typically tends to lose connection during activity- mainly during spin class. A friend of ours introduced the Scosche monitor to us and I have to say that I am incredibly pleased with it. My husband bought me one for Christmas and I turned around few months later and bought him one for our anniversary. We have also recommended this to several people in our spin class who have also purchased it and are pleased with it.

Pros: Stays connected, easy to use, cost effective

Cons: Not readily able to tell remaining battery life on device

Best in class

Written by: Marian from California on March 25, 2015

Crutchfield Customer Review (What's this?)

I have done some research before choosing this product and it seems to be the best. I have tested it couple of times and the results are consistent to what other have said about it. I am happy with my purchase, the only problem is that not all the sports tracking apps I use are compatible with it, however this is not the product fault, but the app's fault.

Pros: More convenient than a chest strap. Easy to pair. Good battery life. Accurate measurement.

Cons: None, yet.

Product Research


Overview: The Rhythm+ Heart Rate Monitor (RTHM1.9) is a workout tool that will help you measure how hard you're working out by monitoring your heart rate, calories burned, distance, pace, and more. The PerformTek precision sensor technology continually measures real-time heart rate data more accurately than a conventional chest strap. It connects via Bluetooth Smart protocol to your smartphone, and works with most popular health and fitness apps, including DigiFit, Runkeeper, MapMyFitness, and Strava. Its extended wireless range lets you work out up to 100 feet away from your device.

ANT+ Compatible: RTHM1.9 is ANT+ certified, and is compatible with displays that support heart rate data, such as watches, fitness equipment, and smartphones. Its dual-mode processor lets you simultaneously transmit your heart rate to multiple ANT+ and Bluetooth Smart devices.

Smartphone Compatibility: The Rhythm+ is compatible with the following devices:

  • iPhone: 6 Plus, 6, 5S, 5C, 5, 4S
  • iPad: mini with retina display, mini, 4th gen, 3rd gen
  • iPod touch: 5th gen
  • Samsung: Galaxy S IV

Monitor Placement: Rhythm+ is worn on the forearm, and placed on the inside or top of your arm just below the elbow. It should be worn snug enough so that it doesn't move around, but not too tight that it restricts arm circulation. The monitor comes with two breathable lightweight armbands (14" and 10" long and 1-1/8" wide).

Waterproof: The Rhythm+ Heart Rate Monitor's sweatproof and waterproof construction is built to IEC Standard 60529 IP67, and can withstand immersion in 1 meter of water for 30 minutes.

Customer Q&A

Crutchfield asked  
Why did you buy this?

A friend and I workout constantly and very intensely. This would help us track our fitness goals. He is very muscular and doesn't like watches. So this is an option that would fit his size. Also, he has a Windows phone and I found an App that works with this on Windows. [ Shannette  Jan 18, 2016 ]
