moofit HW401 Heart Rate Monitor Armband, IP67 Waterproof, Support Bluetooth/ANT+, Rechargeable Optical Heart Rate Sensor Bracelet Works with Wahoo, Strava, Elite HRV

I wanted a heart rate monitor that would control my nordictrack treadmill. This is it I have a treadmill that pairs with an android tablet. I just put on the monitor and the tablet finds it and I tap a button on the screen and it connects and calibrates. The monitor adjust the treadmill to my target heart rate with speed and incline on the treadmill. I also connect a bluetooth speaker for better sound. They both work at the same time. The monitor makes my workouts better. The heart rate override the training video when my heart rate gets to fast or too slow. Rechargeable so I'm not buying batteries.

Compatible with Orange theory

There's no doubt that an ECG (electrocardiography) chest strap heart rate sensor provides superior accuracy, especially for HIIT and RST (repeated sprint training). However, for steady-state zone-2 training, an arm-strap sensor is sufficient and more comfortable for extended sessions—particularly in cold weather with low humidity when getting the chest strap under multiple layers and applying conductive gel can be challenging.Specific to this product, it's comfortable, easy to adjust, and pairs effortlessly with several apps and devices, including my Garmin ForeTrek hiking GPS. It also offers good battery life and a reliable charging mechanism. While this doesn't replace my chest-strap sensor (due to the differences between electrical signals and optical sensing) for sprints, lactate threshold training, or mountain biking on rough terrain—where rapid heart rate changes and physical jarring significantly affect accuracy—it has made heart rate monitoring for steady-state training and hiking much easier and more convenient.

Very accurate and user friendly with the Polar Beat app.

This tracker is great for your orange theory workouts. It’s links your profile and tracks your heart rate and zones back directly to the app. Best of all the price. I can highly recommend it.

Have used this 5 or 6 times now and it seems to report HR into my Wahoo app pretty accurately. Only two complaints. The instructions on how to pair the device are not helpful and it took me a good half hour to get it done. The band can loosen up as you take it on and off and on a recent bike ride the device slid down my arm during a bike ride.

This paired easily with my iPhone and works great with my FitShow app.

I think I'd like it better if it had its own app instead of needing a 3rd party app to use it. It seems accurate as a heart rate monitor. One negative is the proprietary charging method. Instead of a USB C or even micro USB, it has a magnetic connection that requires a special cable. Lose that cable and you're done using the device. As small as it is, maybe they couldn't fit a standard connection method.
